Fibaro Door/Window Sensor battery drain


Recommended Posts

Hi, I'm monitoring hot water heater with Fibaro Door/Window Sensor and attached DS18B20 waterproof probe - temperature values in F are reported via Smartthings hub and seem accurate.


Problem is that reported battery level is draining rapidly - about 10% daily! Referring to the Advanced Parameters in manual, #50 is "interval of temperature measurements", with a default of only 300 = 5 minutes. Why is it so low, and how can I increase to about an hour from Smartthings - is custom handler or script needed?.


Thanks for any help

  • I have an update on this issue, but can't explain it. After the reported battery charge had decreased to 64%, it stabilized there. Then I moved the Fibaro sensor and DS18B20 temperature probe to a different location, reset it and included it with a new SmartThings hub. Now the same battery is reported as 100% charged - so could the battery have originally been a bit loose?
