Been using IoTaWatt for a couple of years without problem. Last week, I had my electricity meter upgraded to a new smart meter. Ever since, I have had a slow down on the IoTaWatt web interface and the HA HACS integration has stopped working (i.e. " * Unexpected error fetching iotawatt data: ‘NoneType’ object has no attribute ‘text’"). InfluxDB uploader seems to work fine.
In the UK, smart meters use zigbee 2.4GHz to talk to the gas meter and display device. The IoTaWatt is directly beside the meter’s comms hub. I have tried switching the WiFi AP’s channel but that doesnt seem to have an effect. Anyone else seeing similar problems? Unfortunately, I can’t just turn of the electricity meter to test if that is the problem!
