Temperature measuring FibaroDoor...

Hi Community!

As seen in this Video

i mounted a Temp Sensor at the Fibaro DoorWindowSensor with a 2 Meter long cable and put it into the pool.
For one week this worked fine! But then a 98% Battery was empty!?!?
Have you got an idea who/why?
On another Sensor i have the same temp.sensor without the cable and this is working for a much longer time now.


Thx for your Help,

Martin

Here's the data sheet for the sensor:

Here's the Fibaro manual:

The only thing that comes to mind is that one device is polling the temperature more frequently and using the battery more. Check parameter 12 on both Fibaro devices to see if they have a different temp sensitivity.

Time for getting the value from DS18B20 is high (about 700ms) - that's why the wakeup time for the sensor is high when using the temperature feature.
The only way is to take the values only with high interval (>=30 minutes) or set a large delta value for reporting the temperature (but this is not s effective, because of chip should then get often the value from sensor - even if not reporting...) So better is disable the reporting temperature difference and use the time based reporting.
