Hi Somersetdude,
I will try the new version soon so if you fix the problem let me know as I will be in the same boat. |

If you use the Node-Red flow supplied, the function node formats the input from the inverter (the RAW MQTT string from Sofar2MQTT) and outputs the formatted information. //running_state //grid_voltage V //grid_current A //grid_freq Hz //battery_power W //battery_voltage V //battery_current A //grid_power W //consumption W //SolarPV W //today_generation kWh //today_exported kWh //today_purchase kWh //today_consumption kWh //solarPVAmps A node.status({fill:"green", shape:"dot", text:""}) |

@cliffdude just got back from working away this afternoon and having a play with HA and that power-dist-card - loving it so far.

@somersetdude, Sorry I can't help with the node red stuff as I don't use
it. Just FYI you can get the info into HA by installing the MQTT broker in
HA and listening to the topic where the invertr is sending the data. You
have done it allready with the Pylontech stuff. There sould be plenty of
info out there on node red to HA maybe check out Dr Zs chanel on youtube.

i have installed node red and have it listening on the mqtt, installed the
json function but i have no idea how to get the data out into HA.... can
you give be some pointers please ?
currently i can link the mqtt through the function and out on a debug but
its just the same message that came in
thanks

No problem i have node Red working for me now and the code supplied does all the conversions, works very well and integrates into HA very nicely. |

Hi both.
Thanks for helping each other to get the most out of this project.
Sorry I haven’t chipped in before now but I’m not a big Home Assistant person. Most of I do is in Node-Red and then fed into OpenEnergyMonitor.
There is a great group on Facebook at https://www.facebook.com/groups/2477195449252168/?ref=share for Sofar owners using either this or a similar Raspberry Pi based solution. Well worth joining if you haven’t found them already.

sometimes I had some weird figures in the beginning of it charging/descharging say 400000w... I changed the code above with this ones for this two variables, I believe I prevent it now... I also change my battery_power identity to battery-power not need to change, but I changed it (it as no impact on the energy tab, because the next two other sensor/identity "eats" the info from the mqtt (from the esp8266)... value_json.battery-power the value from the esp and thus from the sofar this is just an identity with no impact on the energy tab, because I used allways the info directly from the esp...for the battery decharge and charge, they are the ones impacting the energy tab... |

I'm seeing exactly the same behaviour, and have pinned it down mostly to times when the battery current and power is close to zero, often when the inverter is in the wait state with the battery fully charged. My gut feeling is that this may be caused by some sort of under run or parsing error when the true battery_current/battery_power is very close to zero, as it looks suspiciously as if this might be the case. I can't see an obvious cause for this but wonder if its related to the way that the signed integer values used for these two parameters are handled? What stands out to me is that these are two signed 16 bit integer values that regularly go from negative to positive values, depending on whether the battery is charging or discharging. The fix of looking for wildly out of range values resolves this, but I can't help feeling there may be a more elegant way to do this within the ESP8266 code. Unfortunately I'm an old assembly language guy and don't know enough to see if the signed/unsigned integer issue may be the cause. |

You should check out ESPHome, arduino code works great if you know what you are doing but you end up "reinventing the wheel" in many situations as most of the work is already done in the function modules. I have built stuff with arduino too but find ESPHome a good balance of flexibility and ease of use to get it done. |

Ok so I figured it out.. If any variables are initialy set wrong the recorder component will create an entry for them in the database with the wrong defenitions. So anybody that ends up here because their energy devices are not showing up in home assistant should check the statistics_meta table in home assistant's databse for errors. You can see what was wrong with mine in the picture. (NULL and kWhh) |

I just realized that I used and old version of @cmcgerty 's code that was before he created the hybrid and mexxxx versions. I will update my wemos and see what happens as I am still getting some strange values from time to time. It would be nice to add a webserver to the ESP so that we could reboot, change IP settings and check the data coming in from the inverter before MQTT. |

Hi,
With sofar2mqtt usb cable plugged into your laptop and the inverter connected to the modbus wires, you can monitor it using the serial monitor in Arduino IDE. That will give some messages like the command received and the power read from the inverter.
You need to fill in the MQTT parameters to point it at you mqtt server. Mine is called "mqtt" but yours is probably just the IP address of your raspberry pi on line 64. The port will be correct but the username and password need configuring or leaving blank, depending how you set up your mqtt server.
I don't use HA as I find it cumbersome, but your mileage may vary.
Colin

I have worked through this project and think i have the little board working.
(i have built it and flashed it - I am having to wait another 3 weeks for the little screen to arrive).
1- Is there another way I can see if its working?
2- I can see it connected to my wifi as 'sofar2mqtt'
3- I am using home assistant on a RPI - full home assistant OS running the RPI.
4- i believe i need to open MQTT in HA from 'Add Integration'?
5- What do i enter into the MQTT 'broker / port' do i need user and password?
6- When i edited the ME3000SP file i only edited the wifi name and password.
7- I am presuming that as its on the same network the HA should automatically find the sofar2mqtt?

Hi,
Colin has provided an option for diagnostics of the board. You don't need
the display for it to work.
Regarding HA install Mosquito MQTT from the supervisor menu and setup your
user and password. Do not use SSL as it will complicate things. You can
test mqtt using home assistants integrations menu, select mqtt, listen or
via an App on android. Mqtizer works well. Just join the # topic to see all
messages.

Hi,
Looks like your WiFi and Mqtt are working fine but the two wire connection to the inverter in not. Have you tried reversing the wires? The inverter should display RS232 on the LCD when it detects a compatible device.
Thanks,
Colin

I have listened for '#' and i can see the Sofar2mqtt is talking (i think) but no message.

That’s correct. Near the top of the code you see the line “uint8_t slaveId = 0x01;”
This the address of the inverter. It should be set to 01 by default and never needs changing unless you have more than one inverter.
Thanks,
Colin

do i need to address the sofar2mqtt to the inverter so it knows where to look?
in the ME file all I have changed are the WIFI settings and the MQTT parameters

Thanks for the help
Yes tried swapping the wires round but no difference.
I have ordered a replacement rs232 board incase that’s the issue.
I will check out the inverter display tomorrow.
Again thanks for the help

Hi,
Looks like your WiFi and Mqtt are working fine but the two wire connection to the inverter in not. Have you tried reversing the wires? The inverter should display RS232 on the LCD when it detects a compatible device.
Thanks,
Colin

It is normal to not get all the data on each mqtt packet. Mine does the
same thing, now it is a home assistant issue with h9w you setup your
sensors. I can send you some of my yaml code if you wish.

More progress today.
The RS485 board must have been faulty, swapped it out and it now connects
and transfers data back and forth.
I've set up the sensors but they are working intermittently. When i check
the MQTT and listen for # I am not getting all the data each ping. This is
causing my sensors to read 0 most of the time.

If you could send me a sample of your sensors that could be useful.
Thanks

Hi
Many thanks for this set up all appears to be nearly working very well for me.
I have a Nodemcu and a RS485 board connected as per your diagram but without the OLED.
I have mqtt running on Home Assistant and it is receiving from the the ME3000 however some of the figures dont look quite right in particular the Solar_PV figure seems to be adrift by a factor of 10. So when I'm producing 500watts on the PV the Mqtt is receiving a figure of 50.
Maybe i have done something wrong...
This is the information i receive in HA - below the solar PV says 55 when i was producing 554 watts . The display on the ME3000 reads correctly .
