Interesting… I also have Home Assistant, I have 3 Iotawatt units and only one does this…

Heap degradation is usually caused by poor WiFi. Yours is typically borderline (mid -70s) and sometimes poor (-84). That may not be your problem, but Caveat Emptor. Do your other units have better RSSI?

Is your failing unit also the one being queried by HASS?

Yes, all are polled by HA.

I suspected that… I think had made that correlation some time ago.
Not really. They are at 77dBm. But they are attached to a different channel (channel 6). The access point in channel 6 is inside the house. The AP on channel 11 is in the garage. The failing unit is really close to the garage AP (one wall off difference). The other two devices are in the garage and now I wonder why they chose the inside AP.
Channel 11 is generally a bit more congested in the neighborhood… so that could be it. Low power plus high retries…
I am going to try increasing the power of the channel 11 AP to see if I get any improvement.
