[Device Support Request] Frient Electricity Meter Interface2 (EMIZB-141)

[dalte-one]

Problem description

in my setup ZHA is running with the Conbee II. I managed to pair the device well and a power sensor is created. But the values are completely wrong because my electricity meter works with 10000 imp/kWh. And I can not find the value pulse configuration unfortunately.

Solution description

it should be possible to change the pulse rate and see a normal power consumption.

Hi,
same setup and problem here.

Change the pulse configuration with ZHA Toolkit was not working, too.

[themainframe]

I think this is down to Frient/Develco using the "Divisor" option to format the logged/received values rather than to influence the counting. The document describes the Divisor as being read-only, fixed at 1000.

The pulse configuration I think is controlled by attribute 0x0300 of the metering cluster. You can write this with a ZHA Toolkit service invocation:

service: zha_toolkit.attr_write
data:
  ieee: YOUR_IEEE_ADDRESS_HERE
  manf: 4117
  endpoint: 2
  cluster: 1794
  attribute: 768
  attr_val: 4000

For example to set the pulse rate to 4000 imp/kWh

As soon as I even only read that endpoint using:

service: zha_toolkit.attr_read
data:
  ieee: <mac>
  cluster: 1794
  attribute: 768
  manf: 4117

The device completely switches its behaviour, reporting no units, just plain ints, usually just 0.

Something similar has also been reported here: https://community.home-assistant.io/t/frient-electricity-meter-interface2-emizb-141/619377/4

I have to remove, reset and reconnect the device to get it back to working.
