Hi there,

I want to monitor my freezers temperature with Homey.  
The average temperatuur is -20 degrees Celsius, so way to cold for a normal temperaturesensor.  
Now i found the **Alecto OT-03**. This temp sensor has a wired probe. The unit itself can stay outside of the freezer. So it seems perfect for my goal.

Does anybody has any experience with this sensor in combination with Homey?  
I know it is not in the Alecto app but maybe is an other app capable of reading this sensor ?  
(yeah, i know, wishfull thinking)

Peter

Did you checked the temperature range of the Alecto OT-03?

Does the sensor have to be battery operated?

One or more fibaro temperature sensors connected to a fibaro smart implant can be an alternative that is supported.

@fantross

Oh crap,

I did not notice the temp. range.  
Thanks for that.  
(I assumed a probe could get lower).

And no, battery operated it is not nessesary .

Thx  
Peter

I would suggest a Fibaro Smart Implant (Z-Wave), as @Edwin_D already did, or a Shelly Uni (Wifi) with a [DS18B20](https://www.reichelt.de/de/en/development-boards-temperature-sensor-up-to-125-c-ds18b20-debo-lk-temp-p299375.html?GROUPID=9008&START=0&OFFSET=16&SID=9628fa7fad792517495e72e7be16aa2a7b87d977ae81b5640cd4c&LANGUAGE=EN&&r=1) temperature sensor (measuring range: -55 to 125°C).
