Aqara temperature sensor added automatically via G2H HomeKit camera hub shows wrong temperature values for subzero temperatures. Like 90 or 80 degrees instead of -1 or -2 Celsius degrees. While at the same time values visible in Aqara Home App are correct.
I am seeing this issue also. The temperature may be 20c but has multiple drops per day to -50c. Did you find a fix for this?? Thanks
