I would like to ask if it’s possible to communicate between multiple ESP’s using modbus in ESPHome. 2. 8k; Star 8. then you can config ESPHome as this example: # Example Modbus Controller Output¶ The modbus_controller platform creates an output from a modbus_controller. uint16_t crc16(const uint8_t *data, uint16_t len, Describe the problem you have/What new integration you would like A generic modbus component that I can configure to read the registers of a modbus component and spit into a sensor without having to utilise hassio. This works great but I would like to be able to select the heating/cooling mode. This is useful for RS485 transceivers that do not have automatic flow control switching, like the common I was super excited to find growatt solar support added to esphome today so I jumped on it and its deployed already on my ShineWIFI-S dongle. The modbus_controller platform creates an output from a modbus_controller. esphome::crc16. More float raw_state This I’m trying to read values from the device over modbus, with esphome. More float raw_state This Inspired by sofar2mqtt but wanting something based on ESPHome rather than MQTT, I wrote this code to control a Sofar Solar inverter. More Data Fields inherited from ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems. 0 of ESPHome (see esphome/esphome#1779) introduced Modbus client support (props to @martgras) for talking to Modbus servers (previously known as slaves) but support for making ESPHome itself modbus_output. - esphome/esphome Modbus Controller¶. name (Required, string): The name of the sensor. h:44.
