Zigbee H&T sensors reporting 2 decimals precision after HA update
The problem
Today, I updated my Home Assistant to 2025.5.3, and after that I noticed that several Zigbee temperature and humidity sensors suddenly report their measurements with 2 decimals of precision. For example, before the update the sensor reported my living room to be at 20,3 °C, but after the update it reports 20,47 °C.
While nothing is broken per se, it does strike as odd, since I wasn't even aware these devices were capable of measuring with such precision. I actually don't think they are, perhaps they work in F internally and a conversion from F to °C is returning 2 decimals whereas it was 1 decimal before.

n/aAnything in the logs that might be useful for us?
Nothing about ZHA or Zigbee in the logs.Additional information
I use ZHA as integration and I have a Nabu Casa SkyConnect v1.0 coordinator.
I have several of the same sensors, they are shown as "RH3052 by TUYATEC-qun7vq14", and I also have a few others, these are shown as "lumi.weather by LUMI", all of these exhibit the same behavior.
