Aqara Temperature Sensor T1 fails to show/use 2 digits display precision in HA: Solution?

Please consider the attached screenshot. I’m using a few Aqara Temperature and Humidity Sensor T1:s along with IKEA’s “DIRIGERA” Zigbee hub and Home Assistant Core. Everything is well integrated into Google Home, which reports the temperature values as expected (with a precision of two, e.g. “21.22” - red arrow). However, for some reason Home Assistant can’t read the last two digits - instead of “21.22”, it shows “21.00” - yellow arrow).

I’ve set the device display precision to two (green arrow), so it should work - but clearly it doesn’t. No matter what Google Home shows, Home Assistant fails to show the last two digits in a correct manner; they are always set to “00”.

Can anyone here be kind enough to explain why, and what I should do to solve the problem?
