I have three Tuya power meters and they are identified as TS011F_plug_3.
In Z2M->OTA section there is no firmware either shown or available.
When I tried to check firmware upgrade for the following is shown in the log
[1/8/2026, 5:46:23 PM] z2m: Failed to check if update available for 'Master_Bathroom_meter_heater' (Device didn't respond to OTA request)

I did read the device page on Z2M device sections. I do not have (yet) any problems with these devices, but I wanted to check with the audience if even possible to upgrade/replace firmware for these devices and how much effort is warranted for it.
