Aqara Temperature Sensor - Battery at 0% since upgrading HA to 2021.6.4

Today I upgraded from HA 2021.1.X to 2021.6.4, and this is the effect on my Aqara Weather/Temperature Sensor (model: WSDCGQ11LM). Temperature and humidity seem to be reporting fine but the battery indicator is totally messed up:

I tried resetting the device, re-pairing, nothing helps. Wanted to know if this was a known issue?
