Pip 5048Mgx not getting all data from inverter

[ans-gw]

I try this fork,very good jobregistering Mqtt device in Home Assistant, but unfortunatelly i cant get data from: Battery_charge_current_voltronic Battery_redischarge_voltage_voltronic PV_in_current_voltronic = NEEDED PV_in_watthour_voltronic PV_in_watts_voltronic = MOST NEEDED SCC_voltage_voltronic voltronic_COMMANDS

can it be fixed?

thank you

[catalinbordan]

Hi, unfortunately this fork do not have activity. last changes was 9 months ago. You can try my fork. I have tried to combine all the changes from all forks. PV and Load in watthour I have removed because not ok in HA. You can create in HA a sensor: Riemann sum integral sensor and utility meter for that.

[ans-gw]

Ok,I will try. Actually i have already Utility meter in my ha. I take data PV_input_power from my inverter using using a voltronic/mqtt mod from here https://hub.docker.com/r/insanityflea/voltronic-mqtt. and can see here too:https://github.com/syssi/esphome-pipsolar/issues/16 With this mod i can get data from inverter Pv_input_power... You can take a look and see which mods have made. Unfortunatelly i cant do myself,i no have that knowledge.

Thank you

I just try It...Mqtt device is added to Ha but i no get any data in HA. If i check Mqtt data with Mqtt explorer can see the data.... no understand...someting no working.

[catalinbordan]

Look in devices for new device. Here you sold see the new sensors. Like this

[ans-gw]

..yes i can see new device,but dta are all o..battery logo near Mqtt is empty and 0%.

[catalinbordan]

Ok, but you said that in mqtt broker you have values, no? Or in broker you have only the subscriber topics? It is coming values for states? Did you run in console the the command for test to see if it reply with data?

[ans-gw]

I have the value in "Mqtt discovery" on my windows laptop only. I cant understand why no have value in new divece in Ha!?

[catalinbordan]

in your laptop, what program to do use to see on my laptop it is like this:

the command to test in the console it is like this: sudo docker exec -it voltronic-mqtt bash -c '/opt/inverter-cli/bin/inverter_poller -d -1'

Do you have like me? Did you check the credential in config/mqtt.json ? it should be right if you see data in mqtt explorer...

[ans-gw]

Yes...like you. I put my Mqtt user and passw in config/mqtt.json. I thinking to reinstall Ha from scratch,and try again...but need time. Wich version of Mosquitto are you using in Ha?

[catalinbordan]

I have: Mosquitto broker Current version: 6.1.1

Indeed strange... To reinstall HA it is a very radical decision... witch maybe it is not a solution

maybe you changed the configuration after the HA discovered the inverter. try to delete from HA>devices>Mosquitto broker>the inverter>delete device and then restart HA. After a wile if the inverter it is not discovered by HA go in console and do: sudo docker-compose down and then: sudo docker-compose up -d

[ans-gw]

mmm...feel strang also to me... I try already to delte from HA>devices>Mosquitto broker>the inverter>..but same. The only thing different from your instruction is changing in inverter.conf port to ttyUSB1... can be this?..i dont think...

[catalinbordan]

No, if sudo docker exec -it voltronic-mqtt bash -c '/opt/inverter-cli/bin/inverter_poller -d -1' it give you values and you see in mqtt explorer data comming every 11 seconds. the issue it is in HA... for curiosity please share a print screen exactly I like I have done from mqtt explorer. also for test, you can make a template mqtt sensor with the topic seen in mqtt explorer to see in HA if this sensor receive data from mqtt broker.

[ans-gw]

i no understand .. thanks foe help

[catalinbordan]

Hello, sorry to hear that. Unable to open device file (errno=2 No such file or directory) seems the problem it is with installation or connection from inverter to raspberry pi

1. did you follow my instructions from readme? without error? when you build it, is a warning error. that's ok: (warning: pointer of type 'void ' used in arithmetic [-Wpointer-arith] n = read(fd, (void)buf+i, 120 - i);) 100% build it is ok.

2. if you do not have usb connection to inverter, yes indeed you need to change in config/inverter.conf following line with what you used before (device=/dev/hidraw0)

3. in config/mqtt.json you have to change with what you have for HA:
   "server": "192.168.0.2", "port": "1883",

   "devicename": "mpp", "manufacturer": "MPPSolar", "model": "PIP3024MSXE", "serial": "92331908103079", "ver": "2019", "username": "mqtt", "password": "broker", but I supose this it is allready ok, because you see in mqtt broker

4. after you run (sudo docker-compose up -d) and you do not receive data after you run (sudo docker exec -it voltronic-mqtt bash -c '/opt/inverter-cli/bin/inverter_poller -d -1') make a restart of you raspberry pi (sudo restart) and wait 3-5 min run again (sudo docker exec -it voltronic-mqtt bash -c '/opt/inverter-cli/bin/inverter_poller -d -1') to see if it helps to make connection with cable

[ans-gw]

Ok,i will try again. The only thing i made different is: sudo mv ha-inverter-mqtt-agent ha-inverter-mqtt-agentold instead of sudo rm -rf ha-inverter-mqtt-agent,but i dont think this is the problem.

Last line of readme: sudo python3 /bin/monitor.py & mast make this too? Thank you very much

[catalinbordan]

sudo mv ha-inverter-mqtt-agent ha-inverter-mqtt-agentold instead of sudo rm -rf ha-inverter-mqtt-agent,but i dont think this is the problem. i do not thinks it is a problem

Last line of readme: sudo python3 /bin/monitor.py & mast make this too? No! it is for my BMS

[ans-gw]

Ok..i got the data from inverter ,but: PV in watts = 0 W this i need. SCC voltage =0V no needed. mpp_COMMANDS =Unknown . dont know what it is.

The only way i menage to get PV in watts is with .diff file can find here. https://github.com/ned-kelly/docker-voltronic-homeassistant/issues/40, this file diff: https://skyboo.net/temp/ha_local_docker_build_v2.diff and this is a modify image that i actually use: docker image https://hub.docker.com/r/insanityflea/voltronic-mqtt

Hope you can implement this. Thank you very much.

[catalinbordan]

Great! PV in watts = 0 W this i need. SCC voltage =0V no needed.

From a little more reading, it seems your inverter is using a different protocol for qpigs. Hope it only add at the end new variables. please look in manual folder and open pdf at page 4th. then search another pdf on web for protocol for your inverter and try to help me to make a comparation between them and share it here the pdf and what you found. If it is compatible the logic, I will try to look in my free time to see if I can modify the code. I also am not a programmer and spend a lot of time reading all the forks to understand.

_mppCOMMANDS =Unknown . dont know what it is.

this sensor it is for reading what commands you send to inverter from HA. My changes in code it is accepting almost all the commands from the protocol (no more limit of 5 characters).

_The only way i menage to get PV in watts is with .diff file can find here. https://github.com/ned-kelly/docker-voltronic-homeassistant/issues/40, this file diff: https://skyboo.net/temp/ha_local_docker_build_v2.diff_

I look latter to see the differences. It is a lot to read.

and this is a modify image that i actually use: docker image https://hub.docker.com/r/insanityflea/voltronic-mqtt

It took a lot also for me to understand, but actually you do not need it because we build a locally image from what we locally change in folders(ned-kelly image it is old and insanityflea has his changes) if you will look in doker-compose.yml you will see that I comment the image and to use what I have copied locally from my fork.

[ans-gw]

Ok. This my qpgis response and Mgx protocol manual data.Hope can help you. this file .diff https://skyboo.net/temp/ha_local_docker_build_v2.diff has been made to get data from Pv_imput_power. or Pv_charging_Power. You can copy what is added on the diff. I m not able to do,im too noob.

Now is night cant test the solar data...tomorrow surely. Mqtt Device shows all data...exept for "mpp_COMMANDS"= unknown what is this mpp_COMMANDS?.

please let me know

[catalinbordan]

Great! From where you are? Already told you. It is a sensor witch reads the commands you sent from HA to control the Inverter. Like ned Kelly explain in readme. Bonus also it reads the response of Inverter after accepting the command.

[ans-gw]

I m from Italy(around Venice) but I live in Thailand is a small island,Koh Lipe, near border with Malaysia, nice place but electricity cost 0,7 euro Khw! Ooo,very nice dasboard with dropdown menu for battery voltages and setting charging currents... how you did it? can you share yaml? you pubblish in homeassistant/sensor/voltronic or is changed the topic in your fork?

thank you very much

[catalinbordan]

ok, so you are 4 hour ahead of Romania. with some helpers (inputs) and some automations. I will share it with some files in my fork if you think it is useful. It is another. In mqtt.json you have devicename and serial. it is an concatenation between them. in mqtt explorer you will see the topic witch you can use it in your automations.

I am curios how it is looking the output from: sudo docker exec -it voltronic-mqtt bash -c '/opt/inverter-cli/bin/inverter_poller -d -1'

I have put in home assistant folder the examples of what I have for sending commands to inverter, template sensor for warnings, etc. For the input buttons you will use the helpers in HA to create them. The names and the option of them look in automations examples.

Hello, naiss! rain is good :)

Do you have the protocol to sent me? like you did last time. to compare what we have to what we need to do? I think in old protocol we skip W X(we stop at VV.V battery recharge voltage)

VV.V Battery re-discharge voltage V is an Integer ranging from 0 to 9. The unit is V. W PV OK condition for parallel 0: As long as one unit of inverters has X PV power balance 0: PV input max current will be the max charged current; 1: PV input max power will be the sum of the max charged power and loads power. YYY Max. charging time at C.V stage Y is an Integer ranging from 0 to 9. The unit is minute.
