Possible to Limit via Shelly HTTP API?

[IAmWebSA]

Hello,

First of all great Project.

Is it possible to Limit the Power regarding of a a Shelly 3 EM oder similar?

Does this also work with the new purple soyosource inverters?

Best regards

Any power meter measurement can be used. In best case the value is available via MQTT. Consuming HTTP responses is also possible if required: #76

The Soyosource with the purple mainboard can be controlled too. Just the status feedback via RS485 isn't available here. If it's the WiFi dongle version you can retrieve the status and control the settings using the display port (USB jack).

Alright. Please use this schematics: https://github.com/syssi/esphome-modbus-solax-x1#rs485-ttl-module-with-flow-control-pin

And add the flow_control_pin setting to the modbus_soyosource section of your configuration yaml:

soyosource_modbus:
  name: firstfloor_inverter
  flow_control_pin: GPIO4

What's the name/model of your ESP32 board? I would like to make sure the pin D4 is connected to GPIO4. For example the D4 pin of a Wemos D1 mini (ESP8266) is attached to GPIO2.

It looks like D4 in attached to GPIO4 here: https://www.mischianti.org/wp-content/uploads/2020/11/ESP32-DOIT-DEV-KIT-v1-pinout-mischianti.png
