Integrating Sofar2mqtt with Home Assistant
Full instructions to get going with a Sofar2mqtt, Raspberry Pi and Home Assistant.
This is an exhaustive guide, fully documented, screenshotted step by step. This will take around 4 to 5 hours to complete, depending on technical experience.
Prerequisites
Sofar2mqtt
Build or obtain a Sofar2mqtt
I recommend you utilise the 3.3v MAX3485 (Red module) if building this yourself. I also recommend the screen. The screen isn't required but it at least provides some initial feedback about whether your build is working. In short, spend the money and spend less time debugging!
Obtain a Raspberry Pi 4 Model B - Preferably 4Gb.
I recommend you use Facebook Marketplace for local deals, however, I personally use a Pi 400 4Gb
The 400 is identical to the plain Raspberry Pi 4 Model B, however you don't need to build and case the device, and it comes with an integrated keyboard and mouse to save you needing to source separate ones. It is still small enough to tuck to one side once it is all up and running.
Create a file called 'setup.txt' for notes
Save it to your desktop, open it in Notepad and have it ready throughout this guide to save account details and links and tokens as you go along.
Downloading files from this repository
All files are available from the Integrating Sofar2mqtt with Home Assistant folder in this repository.
For the avoidance of doubt, I'd recommend two ways to download the contents to avoid introducing error by copying text or contents from your web browser.
-The first way is to right click on a file, for example Sofar2mqtt.json and left click on the equivalent of 'Save Link As...' in your browser. Save it to a folder of your choosing.
-The other way is to download the whole repository as a zip by left clicking on the green 'Code' button on the front page of the repository, and then left click on 'Download zip'
Accounts you will need to create if you don't already have
Google is more than just a search engine, with an account you are entitled to free storage called Google Drive, an email address and much much more. You probably have one, but if not, sign up using the link in the header. Add these details to your 'setup.txt'.
We will be leveraging Google to store automated daily Home Assistant backups so that in the case of memory card failure, you can easily restore as was.
GitHub
GitHub is a source code management/collaboration tool, but it is also used for authentication purposes. It is free and well renowed in the software development industry. This guide is hosted on GitHub!
Sign up using the link in the header and the click Sign up at the top right of their page.
Follow the instructions to set up and activate your account. Add these details to your 'setup.txt'
DuckDNS
DuckDNS is a tool which gives you a static web address for your Internet connection. Why do you need one? Well, unless you have an extremely fancy Internet connection, every time your router reboots or disconnects from the Internet you will get a different IP address for your next connection. This is the IP address which is used to present your local area network to the world and likewise is the address you need to 'dial-in' to your Home Assistant. The reason different IPs are dished out from a large pool and re-used works on the assumption that not everyone is connected at the same time, saving on the actual number of IP addresses needed at any one time. But it is no good saving a link which could change over time because the chances are next time you browse to your bookmark in your web browser it will no longer work!
The solution? When DuckDNS is configured in Home Assistant later any change of IP address is recorded by DuckDNS and DuckDNS gives you a nice fixed and clean URL such as http://mysuperhomeassistantinstall.duckdns.org regardless of what your IP changes to.
Sign up using the link in the header. Click 'Sign in with GitHub' or 'Sign in with Google' and follow the instructions to set up and activate your account. Add these details to your 'setup.txt'
Once logged in, find the domains section and type in an address. This will be used for your Home Assistant. I am going to be using http://mydan-dan-ha.duckdns.org
I recommend you type something fairly unique and something relatively easy. Don't be surprised if you type in something common and it rejects it - as it will be already used by someone else!
Click 'add domain' in green.
And it will be added to your account:
At the top of your account, please take note of your token and add these details to your 'setup.txt', it will be in the form aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa
You can close DuckDNS for now.
Install Home Assistant
Install Home Assistant
This guide assumes you have a Raspberry Pi and are leveraging Home Assistant Operating System. As such, navigate to https://www.home-assistant.io/installation/ and scroll down to Raspberry Pi and click it. Alternatively, navigate directly to https://www.home-assistant.io/installation/raspberrypi
Follow the instructions to utilise Balena Etcher to flash your Raspberry Pi's memory card with the 64-bit edition of Home Assisant OS. At the time of writing, the version is 9.4, URL is https://github.com/home-assistant/operating-system/releases/download/9.4/haos_rpi4-64-9.4.img.xz
You will need your Raspberry Pi to be hard-wired to your router via an Ethernet cable in the first instance. This guide will concentrate on utilising an Ethernet cable throughout, but it will cover how to swap over to Wi-Fi once everything is up and running.
Once flashed, put the memory card in your Raspberry Pi and boot it up.
You will see quite a lot of text scrolling along the screen as it boots up, however once finished you will be presented with the following screen:
Highlighted in this pic are two elements, first is the Local IP address dedicated to your Raspberry Pi by your router. The second is the URL which you can use to access Home Assistant on your local network via a phone, tablet or computer.
As such, open Chrome or any browser of your choice and navigate to http://homeassistant.local:8123/ or in my case, I can navigate to http://192.168.1.112:8123/ as that is the Local IP address given to my Raspberry Pi by my router. Your Local IP address will be different to mine.
Your IP (in my case 192.168.1.112) should be added to your 'setup.txt' file as Sofar2mqtt will need this to post inverter messages later.
Configuring your Router
Configuring your Router
We need to ensure that
-
Your Raspberry Pi always gets given the same Local IP address, in my case 192.168.1.112, every time it is booted up. Like your Internet connection, it is no good programming Sofar2mqtt with the current Local IP only for it to change when your router dishes out a different Local IP to your Pi! Your router will work like your Internet IP and re-use IP addresses from a pool for the same reasons of IP address shortage.
-
Open up port 8123 (the bit after the colon in the address above) to the outside world so you can access your Home Assistant from anywhere.
I am on TalkTalk so although my steps will be unique to TalkTalk users, the principles are the same.
Navigate to your Router's IP in Chrome, usually http://192.168.1.1 or http://192.168.1.254
It will ask you to log in and the username and password is usually on a sticker on the back of your router.
Click into an area of your router's configuration which deals with your connected devices.
In my case this is called 'Manage my devices' but could be known as 'Local Network', etc.
And sure enough, I can see my homeassistant device:
I click on Advanced so I can change settings, and click into homeassistant:
I can click 'Reserve IP' to ensure that my homeassistant always gets the same address and click Apply:
I can click in Port Forwarding to configure the appropriate port to be opened to the outside world.
I will type in a Custom service name of Home Assistant
Leave Protocol as TCP
Leave External host empty
Type 8123 into External Port
and type 8123 into Internal Port
Click Add
Click Apply to finish
You can close your router's configuration page now.
Initial Setup of Home Assistant
Once I go to http://homeassistant.local:8123/, I am greeted with:
I am going to configure my system with some example details:
- Name: Dan
- Username: dan
- Password: mypass
- Confirm Password: mypass
And I'll click Create Account
You should use your full name and a username and password which are secure enough not to be guessed (as your Raspberry Pi will be open to the outside world) and you should add them to your 'setup.txt' so that they aren't forgotten.
The next screen will prompt you for a name, I'd leave it as default for Home because Home Assistant doesn't just cover off linking to Sofar2mqtt, it can also drive any Hue bulbs you may have, Google Nest products and a whole reap of other home automation kit.
I highly recommend you complete where you live, as this will also help solar predictions and ensure your time zones remain correct for Winter and Summer, if you are in the UK think Economy 7 / Octopus Go charging times. Click Next
Choose whether or not you are happy sharing stats and click Next
And the final step will show any services already found on the network. You can see here it has picked up my HomeKit, Google Cast, Office HomePod and Philips Hue lighting. We don't want to configure those yet so just click Finish.
Now you are in and ready with a fresh install of Home Assistant!
We have plenty to configure now, so let's get to it.

You can close the Device Activation window and in Home Assistant you will see
Just click Finish.
Configuring Home Assistant - Configure Add-ons
OK, let's configure all these Add-ons
Click Settings on the left, click Add-ons and you will see the complete list:
Where the icon is black and white, it means it isn't yet running. You will see Terminal & SSH is coloured in because we started it to install HACS via the terminal interface.
Duck DNS:
Click on Duck DNS
Click Configuration at the top
Firstly, you will see a blank domain with an X at the top, delete it by clicking X.
Get the address you configured in DuckDNS in its entirety handy, in my case, mydan-dan-ha.duckdns.org and get your DuckDNS token handy which should be in your 'setup.txt'.
The configuration page at the time of writing is broken, so click the three dots at the top right of Options and click 'Edit in YAML'
In the square brackets in domains:, paste in your address from DuckDNS without the http://, i.e. mydan-dan-ha.duckdns.org
Within the quotes for token:, paste in your token from DuckDNS.
Click 'SAVE'
Click the Info tab at the top and click START.
When started, click the Log tab at the top and if successful, you will see a message in green either indicating there's no change, or that it was successfully updated. If it hasn't worked, double check your address, your token, and try again.

Sofar2mqtt
Gather your details
Now, we need to take the details of our Mosquitto broker now running on our Home Assistant box and plumb them into Sofar2mqtt.
From your 'setup.txt' file, you should have the Local IP Address of your Raspberry Pi. In my case this was 192.168.1.112
You should also have the username and password we configured in Mosquitto. In my case this was
- username: battery
password: Switch1I am assuming you have followed the build and configuration instructions on the Sofar2mqtt site, and that you have Arduino open with Sofar2mqtt.ino ready in there.
- One thing Sofar2mqtt does not mention is D1mini drivers. Install the drivers from https://www.wemos.cc/en/latest/ch340_driver.html if you need them.
Editing Sofar2mqtt.ino
At the top of the code there are definitions you need to configure based on what we have just done.
- If you are using an ME3000 then ensure the ME3000 line begins #define and that the HYBRID line begins //.
- If you are using a HYBRID then ensure the ME3000 line begins with // and that the HYBRID line begins #define.
- Type in your Wi-Fi name between the quotes for WIFI_SSID
- Type in your Wi-Fi password between the quotes for WIFI_PASSWORD
- Type in your Local IP Address of your Raspberry Pi between the quotes for WIFI_PASSWORD
- Type in your Username you configured in Mosquitto earlier for MQTT_USERNAME, we used battery
- Type in your Password you configured in Mosquitto earlier for MQTT_PASSWORD, we used Switch1
Save this as Sofar2mqtt-customised.ino, that way you have this file to fall back to pre-configured with your details.
- Remember, if your Wi-Fi changes, you will need to update the WIFI_SSID and WIFI_PASSWORD to suit the new router.
- Remember, if your Raspberry Pi changes, you will need to update MQTT_SERVER, MQTT_USERNAME and MQTT_PASSWORD to suit your new config.
Flash this using the Sketch -> Upload menu.
Node-RED - Sofar2mqtt.json
This flow imports the data from Sofar2mqtt and presents the results to Home Assistant as sensors.
Download Sofar2mqtt.json from this GitHub repository
Click Node-RED on the left hand side
After a pause, you will be greeted with the Intro:
Skip through the intro
At the top right, click the three-line menu burger and click Import
Click 'select a file to import' and browse to the Sofar2MQTT.json downloaded a few steps ago.
Click 'new flow' for Import to
Click Import
The flow will appear in the right hand side, and also in a tab at the top. Click the tab:
We just need to configure the Mosquitto details and we are done.
Double click the purple Sofar2MQTT node on the left and the following properties screen will open:
Click the Pencil alongside 'Home Assistant Mosquitto'
Click on the 'Security' tab and type in our Mosquitto username and password configured earlier.
In my case, these were battery and Switch1
Click Update
Click Done
Click Deploy at the top right. Once deployed, you will see that the MQTT node Sofar2MQTT has connected:
OPTIONAL Node-Red - Economy7Management.json
This flow will automatically charge the battery to 100% and keep the load powered by the grid until the end of the Economy 7 time period. This is useful if you are leveraging Econonmy 7 and also within winter months where solar generation is poor.
At the top right, click the three-line menu burger and click Import
Click 'select a file to import' and browse to the Economy7Management.json downloaded a few steps ago.
Click 'new flow' for Import to
Click Import
It may prompt "Some of the nodes you are importing already exist in your workspace", just choose 'Import Copy'
The flow will appear in the right hand side, and also in a tab at the top. Click the tab:
We just need to verify your Economy 7 or Octopus Go times. Double click the orange Format node and the following properties screen will open:
Scroll down to the part of the code shown in the screenshot above to configure your cheap rate tariff. It is defaulted to 00:35 and 07:25.
Click Done
Click Deploy at the top right. Once deployed, you will see that the MQTT node Sofar2MQTT has connected:
If you want to disable this, open Node-RED, click the 'Economy 7 Management' tab at the top
On the right hand side list, there is a white circle next to Economy 7 Management labelled Disable. Simply click this as below:
MQTT Integration
We need to connect Home Assistant to our Mosquitto broker which runs alongside it. We do this like so:
Click on Settings on the left hand side
Click Devices & Services
Click the CONFIGURE button under MQTT:
It will prompt 'Do you want to configure Home Assistant to connect to the MQTT broker provided by the add-on Mosquitto broker?'
Click SUBMIT
It will then auto-configure for Mosquitto and leave you with the following:
Home Assistant - configuration.yaml
The configuration.yaml is the file which contains all the Home Assistant configuration. We will take a backup of it now.
Click File editor on the left hand side
Click the white folder icon at the top left
Click on configuration.yaml in the config/ folder:
In the right hand side you will see it is a pretty simple config at this stage. To save it locally, copy and paste the contents to a new Notepad and save the file to your desktop as configuration-backup-2023-01-06.yaml. Change 2023-01-06 to reflect the yyyy-mm-dd you are doing this. This is just a safeguard.
Download the configuration.yaml from this GitHub Repository
IF YOU ARE USING A HYBRID INVERTER, download and use hybrid-configuration.yaml
Open the file in Notepad
Copy all the contents using Edit -> Select All and copy using Edit -> Copy
Back in Home Assistant, delete the contents in the window already:
and paste the contents so it looks like this
Click the reddy-orange SAVE button at the top right.
Click 'Developer Tools' on the left hand side and click 'Check Configuration' and if all is good you should get a green message:
Click RESTART and confirm by clicking RESTART in the confirmation box.
Once back up and running, we only have dashboards to configure!
Home Assistant - Dashboards:
There are two dashboards, one which shows all information in real-time. The second is to do with inverter control.
Real-Time Info Dashboard:
Click on Settings and then click on Dashboards
Click + ADD DASHBOARD at the bottom right.
Configure a dashboard called SOFAR
Choose an icon, I used mdi:solar-panel
And ensure Show in sidebar is ticked
Click Create
Click SOFAR which will now be at the top left hand side. Click the three dots on the far right side and click Edit Dashboard
Tick 'Start with an empty dashboard' and then 'TAKE CONTROL'
Click the three dots at the top right and click 'Raw configuration editor'
Select all the text currently in there and get rid.
Open SofarDashboard.txt from this repository in Notepad and copy and paste the contents into the window like so:
IF YOU ARE USING A HYBRID INVERTER, download and use hybrid-SofarDashboard.txt, your dashboard will be called SOFAR Hybrid, but you can rename it.
Click SAVE at the top right
Press the X at the top left
Then click DONE at the top right
Your dashboard shouldn't look too different to the following:
Clicking on TODAY'S POWER DIAGRAM will give you today's picture in a graph:
If you get a problem on any of the tabs, for example the TODAY'S POWER DIAGRAM you may see 'Custom element doesn't exist: apexcharts-card' then I found this just to be a bug in HACS.
To overcome, click on HACS on the left hand menu
Click Frontend
You will see all the elements which are Not Loaded in red:
Click on any
Click the three dots menu at the top right
Click Redownload
And click Download in the popup
When done, click RELOAD
Repeat for all other unloaded elements.
Inverter Control Dashboard
Click on Settings and then click on Dashboards
Click + ADD DASHBOARD at the bottom right.
Configure a dashboard called Inverter Control
Choose an icon, I used mdi:remote
And ensure Show in sidebar is ticked
Click Create
Click Inverter Control which will now be at the top left hand side. Click the three dots on the far right side and click Edit Dashboard
Tick 'Start with an empty dashboard' and then 'TAKE CONTROL'
Click the three dots at the top right and click 'Raw configuration editor' as before.
Select all the text currently in there and get rid.
Open InverterControlDashboard.txt from this repository in Notepad and copy and paste the contents into the window like so:
Click SAVE at the top right
Press the X at the top left
Then click DONE at the top right
Your dashboard shouldn't look too far away from the following:
Home Assistant via your Smart Phone or Tablet, Home or Away
If you want to access Home Assistant on your phone or tablet, download the Home Assistant App or use your appropriate web browser.
Web Browser
If using a web browser, simply browse to your DuckDNS URL when away from home
For example, I will use http://mydan-dan-ha.duckdns.org:8123
If your router is smart it will also work if you are on Wi-Fi. If not (like me), you will need a second bookmark of Local IP:8123
Where Local IP is the IP assigned right back when Home Assistant was first installed.
For example, I will use http://192.168.1.112:8123
App
Find and install the Home Assistant app via Apple's App Store or Google's Play Store
When using the app, it is an identical configuration, simply use the details as per the Web Browser approach.
Bear in mind likewise that, if your router doesn't support internal redirection then you will only be able to configure the Home Assistant app to work when at home or away.
Personally, I'd set up the app for use at home using the Local IP, and use a web browser when away. But the choice is yours.
Home Assistant and Wi-Fi
Once you are configured using a cable you can switch to Wi-Fi but bear in mind the following
- You will get a new Local IP assigned to your Raspberry Pi
- You will need to update your documentation and links to reflect this new Local IP
- You will need to re-configure your router to ensure the Local IP is reserved and the port 8123 instead forwarded to this new IP
- You will need to re-flash an updated Sofar2mqtt to your device with the new MQTT IP
- All the steps above are covered earlier in the documentation
To Swap
Click Settings at the bottom left
Click System
Click Network
Scroll down to Network Adapter and configure your Wi-Fi settings. Once done and saved, unplug your network cable and reboot. The boot-up sequence should point to you the new IP as per:

Version History
V1 - Initial Release
Initial release
V1.1 - 2023-05-16
Home Assistant now requires 'device_class' set to 'enum' for sensors which return text, as such, configuration.yaml modified so that sofar_inverter_state, sofar_grid_status and sofar_battery_status now include this declaration.
If you have this problem on a custom configuration.yaml, simply add device_class: "enum" to each of the three affected sensors in your configuration.yaml, ala:
