Hi again. Got VSR300 with IAM in ModBus mode. Problem is ModBus integration always restarting and drop connection to gateway due tons of communication errors. It's normal or i doing something wrong? (log attached)

It seems like it does not connect properly. Have you tried to read data via some modbus tool from your computer? https://www.modbustools.com/download.html

You could test your settings and see if you would have to change settings in HA. At least faster than testing via HA.

Hi, sorry for late answer.

I tried to read modbus registers via Modbus Poll - all ok. image

At HA when i switching modes (Low<->High) for example - it's happen only at 50+ click and after 10-30 minutes.

At log's it's spamming by error reqesting 1110 register mostly. image
