Temperature Sensors ‘froze’


Recommended Posts

Hi all,

a newbie here.


All of my room temperature sensors froze to a certain temperature and stopped measuring.

for example- living room temperature shows 24,3 (even though another room thermometer shows 21,5) and heating wouldn’t start unless I manually set desired temperature to 24,5 and above. It also doesn’t switch off the heating because it doesn’t know it has reached 24,5, so it keeps going until I stop it manually. It’s like that in all rooms with different t to each one.

it’s not battery issue because they still measure motion and the light in lux. Also it would be very strange if it is battery since it’s in all rooms at the same time. 


Any ideas why it has happened and how to fix it? I’ve restarted the home Center without any change. Can I restart all sensors from the browser view maybe? 

/just to mention (not sure if related) 

I started using Yubii to control the system while my partner is still using Fibaro app. /

Hello, I have the same issue, I stopped using the temperature from my Motion Sensor to

Control heating systems. I hope some experts can help us to properly configure the parameters 

In order to have an accurate measurement of temperature.

@alexandropolis4eHi are you using the fibaro FGMS-001 device?


For switching, I only use Temp Sensors with power supply like the Aeotec Multisensor 6 or Fibaro Smart Implant with one or multiple  DS18B20 Temp Sensors.


Look here for a full room zwave thermostat from heatit

This is much more reliable than a battery powerd Temp. Sensor.
