ZHA issue with clamp meter pj 1203a killing network

Hi

I have a zigbee network with around 20 devices and a sonoff usb zigbee stick

The network has been solid, until i added a new device

The device added is a Tuya dual clamp meter with an addon quirk to present the data in zha.

The issue is when a load is applied to the appliance monitored by the clamp meter, after several minuets or hours all other zigbee devices fall silent and zha can only receive reading from this one clamp meter. No load and everything works fine.

Turning off the clamp meter doesnt fix it, restating zha or unplugging the zigbee stick and reinstall fixes it.

Whats odd is before zha fails, the lqi of this device goes from 0 to 130, then all other devices stop reporting. This device is quite far away and so i dont believe the lqi could be that good maybe its connecting through another router on the zigbee network.

Anyone else had issues like this with clamp meters?

Thanks

Hi

This was fixed by adding an external antenna to the zigbee power monitor increasing the LQI to the zigbee router.

Thanks
