EBYTE Zigbee to RS 485 Modbus E180-DTU(Z20-485) #2919

Closed Jusch777 closed 2 weeks ago

Jusch777 commented 7 months ago

Problem description

I purchased a device from EBYTE which should convert RS485 registers to Homeassistant. Registers are read and write with function 03 and 10 Want to use this device to connect my EV Wallbox which communicates only serial via RS485 . Connection is in Garage, so need Zigbee network to get over a distance of 20 m.

Issue: Homeassistant pairs with the device, but only 3 useless entities are provided: LQI RSSI Identify

The Wallbox requires to read and write Register 1000 - 1010 and 2000-2010 Read function is 03 Write function is 10 (write multiple registers)

Solution description

There is a documeentation of the device communication. But I am not able to find out how I can create Entities in Homeassistant for the entities of the certain registers.

You need to provide the device signature and/or diagnostics information for that device. It can be found on the device page.
