Modbus Serial behavior

, ,
1

Hello,

I have already configured my Energy Meters with modbus binding.
OpenHab 3.3.0 (Openhabian RPi4)

I have configured 2 Meters, one from them I need two data pollers. Here I have following behaivor …

  • if both data pollers are read
  • a reading value in the secound data pollers set to one and after them it was set to the reading value

It is something special with 2 data pollers on one modbus id?

Regards
Jürgen

Don’t understand you here.

No.
You’d better show us what you have done with your Things, use code tab

  • on modbus data is during readen first 1 (0.01 with transform) and then the real value from data poller

Data Poller 1:

I don’t see any particular issue.

If you haven’t restarted the binding (or openHAB) since the last time you edited your Things, try that. You may have ghostly leftover config from before.

Yes I have restarted openHAB, but I tried it again.

For your information, when I disable the data poller “ABB DataPoller 20480 (5000)” everything works fine.
The behavior only occurs when both Data Poller were reading together. When I set the refresh from both Data Pollers to the same value, the behavior occurs on every read.
