I bought two Tuya WIFI thermometers and connected it to HA via Tuya integration.
However after one day of observation both of them have strange peaks on history graph like this:
Since it’s battery powered the reading intervals are actually pretty smart. If temperature doesn’t change much over time it simply doesn’t update it. However when big change occurs it reports even every few minutes. It’s all for saving battery. This way WIFI is most of the time turned off.
Don’t believe it.
There is no way a room can have the same temperature during 12 hours.
And also dropping during daytime lower than nighttime makes it even more strange in my opinion.
Here is my temperatures.
The timespan is five days.
