Iolloi Zigbee dimmer module

[Brians5231]

Hi,
I am having an issue with a particular device that I have quite a few of in my Z2MQTT setup in Home Assistant. It's an Iolloi zigbee dimmer module ID-UK21FW09
It's the version that is designed to be put behind the switch plate.
They seem to work fine but are sending constant error messages making it hard to pair new devices. It looks like iolloi might not be selling these anymore so maybe I might have to replace them but just seeing if anyone has any idea if this can be fixed with anything in the Z2MQTT setup.

A typical log for starting Z2MQTT is:

[22:46:57] INFO: Preparing to start...

I have 11 of these devices and they constantly send error messages like the ones above. I have 50 or so other devices on the network that don't give any issues at all.

I use the SLZB-06M Coordinator over POE and it is central in the kitchen away from any power sources that could cause interference.

Thanks,
Brian
