I have a lot of Tuya ZigBee TS0601 temp&hum LCD-display sensors installed in every room and several sensors without LCD-display outside and inside (perhaps Sonoff). Until October, everything worked with a Tuya Smart app and their cloud.
In October I’ve got a Rasperry Pi 4B 4GB and I installed HAOS onto it with Sonoff’s ZigBee 3.0 USB Dongle Plus. Again, all were ok with the sensors, until the temperatures in some rooms have felt below 0 degrees by Celsius. The Tuya LCD sensors started to send 6,551.5 C as temperature value (it’s not constant, it changes with the negative temperature and becomes normal above the 0). Those without LCD (Sonoff) work well.
I have installed the latest core and OS of HA but it didn’t help. I have no access to the house, it stays alone and waits the spring. But my heating is (waterpipes!) is depending on the temperature values!
Can anybody help to find out and solve the problem? All positive values are still OK till zero.
If I’m looking on the graphs, it seems (maybe) the 6,55x is a negative value. As on the 2nd graph, 6,553.4 might be -0.4. I’m wrong, another graph shows rising values 6,552.1 → 6,551.7 → 6,551.5. Maybe these are -3.4, -2.1, -1.7, -1.5. So, 6,55x might be the negative…
I checked the attribute “measured_value (id:0x0000)” and it’s 655150.
