I just noticed one of my zigbee temperature and humidity sensor is reporting: MINUS 19.5 °c, 53% humidity, firmware unknown, battery 25%...I replaced both batteries, and indeed , one was dead (0.6V).
I am now facing a lot of issues... only LQI is reported and led stays "on"... I think this unit is dead/faulty.
Two other temperature sensors of the same "brand" (LOL) are working fine. One is even outside for 18 months. (finger crossed)
I 'm now searching to replace it.
I would like temp+humidity, normal batteries, batteries lasting over 6 months... but also reliable 😉 .
If you have plenty of unit for a long time ( > 2 years), let me know ... Thx
🤔 🤪 strange .
