How to start?

[VoyteckPL]

Hi, i have the same heater, ariston Genus one. What device should I buy to read data via ebus? Is it 2 way communication? I have ethernet near heater. Will appreciate help!

[mihaimdinca]

I bought ebusd adapter v5 with WiFi (based on esp32) from https://adapter.ebusd.eu/v5/#wifi and works pretty well for both reading and changing boiler settings. I use it with the ariston.csv file provided by this repository, Home Assistant OS installed on a RPi 4B and the eBUSd addon.

Guys, please use english here..

[mihaimdinca]

I apologize. You are right. Still trying to figure out what issue he is having or what question he is trying to ask. I will give an English description afterwards if we cannot do it in another way

[komw]

I'll appreciated if you will be able to make a pull requests with help instructions in Readme.md

[mihaimdinca]

I will try my best. The csv file you made available is extremely useful for my use case. I got most of what I want from my ebusd adapter and I will try to write a complete noob tutorial for my use case (that hopefully will, at least in part, work for other use cases)

[wrongisthenewright]

Hi, take a look here:

https://github.com/wrongisthenewright/ebusd-configuration-ariston-bridgenet

I already wrote a little tutorial for beginners.

[mihaimdinca]

Thank you!

[mihaimdinca]

This is not a proper tutorial and is only based on my experience with my particular use case. My setup is like this: Ariston Genus One heater + Ariston Cube S Net, Home Assistant OS installed on a Raspberry Pi 4B. In order to get the Ariston Genus One integrated in Home Assistant there are several options:

1. HomeKit integration

   • it is the easiest, probably, as the Cube S Net is HomeKit compatible. You do not need any other hardware and it does not rely on the cloud. Unfortunately, it only supports setting the room temperature and changing the mode between heat and off. Sometimes it does not turn back on and you need to do it from the Ariston app or manually.

2. The Ariston custom component integration (https://github.com/fustom/ariston-remotethermo-home-assistant-v3)

   • is very easy to install and creates almost all entities you need (from thermostats to sensors to energy and gas consumption) but relies on the cloud and that is sometimes slow and other times (like today) it is unavailable for technical reasons that you cannot influence

3. The actual topic: Using the eBUSd adapter.

   • i have a eBUSd v5 (based on ESP32-C3) bought from this site https://adapter.ebusd.eu/v5/.
   • connect the adapter to a 5v power supply via the microusb port. The adapter only works with a 5v power supply and does not use power from the eBUS line.
   • follow to basic setup totarial provided by the manufacturer in order to connect it to the network. Make sure you set a fixed IP and connection is TCP with enhanced protocol
   • connect the eBUSd adapter to the eBUS line (the two wires that connect the thermostat and the heater) in parallel with the heater and the thermostat (polarity does not matter)
   • install the eBUSd addon for Home Assistant OS (use the Home Assistant Add-on store, add this link https://github.com/LukasGrebe/ha-addons/ to repositories and after a few minutes it should show up in the addons list)
   • download the ariston.csv file provided by komw in this repository
   • this file needs to be placed in the /config folder. You cand do this by using the filebrowser addon (add this link to repositories https://github.com/alexbelgium/hassio-addons) and you can upload the ariston.csv directly to the homeassistant folder. Another option is to install the Advanced SSH and Web Terminal and use WinSCP (https://winscp.net/eng/download.php) to connect to Home Assistant OS and copy the ariston.csv in the /config location.
   • make sure you have a running Mosquito MQTT server on the home assistant device. It can work with other MQTT servers but you need to specify it in the eBUSd addon configuration. I used Mosquitto and there was no need for manual configuration.
   • configure the eBUSd addon like the following (my topic is ebusd but it can be any name, my local IP for the eBUSd adapter is 192.168.1.95 - change this to match yours, port 9999 should be the same for you): scanconfig: true loglevel_all: notice mqtttopic: ebusd mqttint: /etc/ebusd/mqtt-hassio.cfg mqttjson: true network_device: 192.168.1.95:9999 mode: ens configpath: /config
   • save the configuration, connect the heater and the adapter to power, restart the eBUSd addon and wait.
   • you should have 3 new devices created by the MQTT integration in home assistant: two related to the adapter itself (firmware version, connection etc) and the third should have the same name as the mqtt topic you configured earlier plus the word boiler. the entities I get are the following:

Many of these entities, that appear as sensors can also have their values set through MQTT. You can do that through service calls in Home Assistant. In order to create a climate entity to easily set room temperature and a water heater entity to adjust DHW temperature easily you can add this code to your configuration.yaml file. Please change the ebusd part with the name of you mqtt topic, also I used the eBUSd adapter MAC as unique ID, you should use your own:

[mihaimdinca]

It is far from perfect and I am sure I overlooked some stuff but we can improve it through your questions, answers and contributions.

[mihaimdinca]

The eBUSd boiler mqtt device will provide most raw controls and information you need. In my case the most important info I do not get (I do not know why) is the heating circuit water pressure.

[wrongisthenewright]

Thank for the update, if I may...the tutorial have the assumption that you are using HASSIO (the complete OS from HA or a supervised installation of HA). If like myself you have only the core version you should install all the add-ons as individual dockers.

The second thing is : can you quote the code with the appropriate tag in GitHub? It should make easier to copy and paste the configuration as the indentation should remain valid.

Many thanks again

[mihaimdinca]

Thank you for pointing that out. I use Home Assistant OS. Not a supervised installation. I will repost the code shortly.

[Alfy1080]

Has anyone tested this with an Ariston Alteas One+ NET boiler, or are there any chances for this to work with that model? My primary concern is to be able to control the boiler (ON/OFF) without relying on the extremely slow and sometimes downright unresponsive Ariston Cloud.

[mihaimdinca]

For on/off and temperature control, the Homekit integration should work. If your thermostat is anything like the Ariston Cube S Net

[mihaimdinca]

Using the eBUSd adapter and the Ariston.csv allows way more options but I can only confirm it works with Genus One + Cube S Net. Likely it will work, at least partially with your setup but I guess you or someone else will have to test it out and see.

Do you have a wiring diagram? I have ariston Genus one too.

[mihaimdinca]

You just connect the two bus wires of the eBUSd adapter in parallel with the thermostat. Polarity is not important. You need to power the eBUSd adapter from a separate source via the microusb connector.

[Alfy1080]

Unfortunately i have the wired Sensys thermostat which is not homekit compatible. I'm not even planning on still using that thermostat or any other thermostat for that matter, so no paralllel wiring needed in my case. My plan would be to have local control of the central heating (on/off) and if possible, setting the temperature of the domestic hot water heater. My current setup is based on trv valves and ambient sensors in each room so the sensys thermostat right now is an oversized and overpriced on/off switch

[mihaimdinca]

You should be able do use any dry contact smart relay in that case. I have not tried it in my Genus One but I know it has a separate connector for a standard thermostat (which is basically a contact that goes on and off).

[mihaimdinca]

A Sonoff module like RE5V1C flashed with esphome should work great locally

[Alfy1080]

I researched that option as well and did not find any indication that a dry contact relay would work with the alteas one+ net. Has this been tested before by anyone here? Also this option would only work for turning the boiler on/off for heating which is great, but the domestic hot water heater temperature would still need manual interaction if needs changing.

I do also have the intention of exploring other automation possibilities in the future, assuming that i manage to make the basic functionality to work. For example i was hoping to eventually be able to control the radiator flow temperature based on outdoor temperature for peak efficiency and(not sure if this is or will be possible) monitor gas consumption locally. Right now for some reason my energy consumption stopped updating since 2 days ago both in home assistant and in the Ariston NET app and the support person from Ariston whom i've contacted has no idea why. Btw is this a general issue with the Ariston API or is it just me? I had quite some funky issues lately with their cloud so i would like to bypass it as much as possible, if not cut the internet to the boiler altogether.

[wrongisthenewright]

For the basic onoff feature you can connect any dry contact switch to the TA port of the boiler PCB. In your case you should use TA1 (Termostato Ambiente 1 in italian, it means room thermostat 1). Be sure is volt free/dry contact or you'll fry your boiler PCB. Obviously you can use a smart switch for the purpose , the boiler PCB has convenient N,L connectors near by.

The Ebusd integration gives you a little more info and you can set some parameters via automation.

ATM I'm not able to gather gas consumption metrics from the boiler but I'm theory it should be possible as the info is stored locally to show in the statistics.

That's fantastic news. I was not aware of a separate connector for dry contact switches(i've just got this boiler less than 2 weeks ago).

If i were to set up a dry contact switch, would i still be able to have the sensys thermostat or an ebusd adapter connected at the same time to the bus pins just for grabbing info from the boiler locally while leaving the on/off controls to the dry contact switch?

[wrongisthenewright]

Yes you could, but first, please read all the manuals the user first to understand the basics and the installer one for the wiring info and the advanced settings as you'll probably have to configure the boiler to give precedence to the external thermostat/smart switch over the native one.

I will definitely do that. Thanks for the valuable information! :)

On a slightly different topic, does anyone know if the ebusd adapter could be used also to publish the temperature value from a sensor in home assistant as the value of the outdoor temperature sensor of the boiler? I don't have an outdoor temperature unit and i am planning on purchasing a weather station to integrate in home assistant and i was wondering if i could get away with just the weather station info to use for the boiler's automatic thermoregulation feature. Right now it's using the internet weather temperature and that tends to be a bit inaccurate from time to time. Would I need a second ebusd adapter to connect to the pins for the external sensor?

[wrongisthenewright]

It's theoretically possible, you should publish via ebusd the correct value for you appliance. But I see it as troublesome and prone to fail in the long run The original Ariston external probe is not so costly, you can also find online the circuit specifics to DIY a custom one (it's a basic NTC thermistor) and it's connected by a 2 wire cable. In my opinion you should stick to that choice. More robust. In my view the domotics should do "fun" stuffs, the basics should be rock solid. I wouldn't want to be cold because some geek put out an upgrade that broke my automation....

Hello guys, I received ebus Adapter. I connected it to Ariston Genus One with water tank. I run HassOS with Ebus addon. The communication is there but I can't see some parameters for example:

slope pwm pump

The question is which excel I should use? and are there any other files that should be loaded to /config or elsewhere?

[VoyteckPL]

For example I don't see the current DHW temp:

[mihaimdinca]

Using the ariston.csv provided by komw i do get the dhw temperature but it is calld dhw_comfort_temp. I have an Ariston Genus One 35 connected to an Ariston Cube S Net.

[VoyteckPL]

Can you send the current csv? I still don't have access to current water tank temperature.

[VoyteckPL]

dhw_comfort_temp is a target hot water temperature in my example. I can see hot water temp on via Ariston App but in MQTT messages I cannot see it. Can someone please paste the lines I should use in CSV? I have latest by komw + Ebusd as home assistant addon + Ariston Genus One + Cube S Net.

[VoyteckPL]

ok I added the following line and it works:

r,boiler,dhw_tank_temp,dhw tank temp,,,,6510,ign,s,IGN:1,,,,dhw_tank_temp,s,SIN,,°C,,,,,,,,,,,,,,,,,,,,,,

But I still have problem with many parameters not visible. For example how to activate "Heating Only" mode (Heating on, DHW off).

[Alfy1080]

Just received my ebusd adapter today and first of all, many thanks to @mihaimdinca for your very comprehensive and detailed guide and to everyone involved in this project. The whole ebusd setup on my Alteas One+ NET took me less than 15 minutes. I am now able to see the following info from my combi boiler: There are a few entities that are unavailable for some reason though. I have also created water heater and climate entities for easy control and these work great also.

Now that the basic functionality is there and I am extremely happy, i'm thinking of attempting to grab even more data from the boiler. Are there any pointers as to where to start this journey of identifying what needs to be added to the csv file in order to get info like circuit pressure, wifi signal, heating flow offset, external temperature offset etc?
