Soyosource esp8266-wifi-dongle-and RS485 example.

[ASAS443]

Soyosorce GTN inverters
Does anyone heve this work.
I am missing guidelines.
Wich hardware connections have tot be made.
HA is showing the entitys.
But hardware connections do not work:

• Wifi dongle
• Uart > RS485 > Inverter ( > messege: Offline.)

Could you provide a photo of your setup and a ESPHome log?

[ASAS443]

[syssi]

Your setup is incomplete. You haven't attached the ESP to the display port of the WiFi dongle. Which Inverter model do you own? The one with or without a display?

Please post a ESPHome log, your current configuration and a short description of your expectation.

I think I know to little to get it to work properly and completely. :(

The UART works fine just like soyosource app.
The RXTX is now working. Don't know how I got this together. Did many times the same in uploading and connecting wires. ??

The imported power entity (P1) from HA in the YAML gives no errors but I don't see it function anyware.
sensor.p1_meter_vermogen_fase_3
This is, I hope, the last problem.

 - platform: homeassistant
    id: powermeter0
    name: "${name) Instantaneous Power"
    entity_id: sensor.p1_meter_vermogen_fase_3 # Homewizzard # powermeter0 #  
    filters:
     - throttle_average: 15s

The YAMl is in the ZIP file.

Hope You get me going again.

Could you verify the sign of your power sensor?

[13:55:31][D][homeassistant.sensor:024]: 'sensor.p1_meter_vermogen_fase_3': Got state -440.00
[13:55:31][D][sensor:098]: '${name) Instantaneous Power': Sending state -440.00000  with 1 decimals of accuracy
[13:55:31][D][soyosource_virtual_meter:096]: 'firstfloor_inverter': Using the new method to calculate the power demand: -440 0

What's the meaning of -440W? Do you import 440W from your grid provider or are you exporting 440W because of solar surplus?

[syssi]

Could you make a photo of your ESP+RS485+Soyosource connection?

[ASAS443]

The RS485 connection is working now :) Don't know what has made the difference. Wonderfull world of HA!?
The value is from phase 3 and shows the sumup of solar power and power used in the house. It was negative because there was more solarpower (It was exporting -440). I changed it to total power reading.
All is working now. Took me about 24 hours.
Could the value of total power made visual? Can you tell what I need to add to make it visual in the soyosource YAML.

INext step is my other 2 inverter. 1 display/1 no display. 1 ia underway from Alie. Its a new model with display and wifi

Good morning Sebastian, It's looks like al is working fine now. Many thanks for making the project with Soyosource and support you gave me. I start now with the next inverter to automate in HA Maybe we mail in the future again. For now have a nice day and thanks again. Greetings, Andre
