Crazy idea ? external power supply to door sensor
Posted: 25 Mar 2018 21:20
Hi
Am i crazy if I want to connect an external power supply to the fibaro door sensors ?
The idea is to use the sensor with the battery so in case the power has gone off the sensor will continue to work.
Required:
- rechargeable battery 14250
- This one to provide 220V-5V
https://www.ebay.it/itm/Alimentatore-5V ... SwwChar~v7
- It will be connected to this one to have a recharge module and not overload the battery

For less than 10 euros we have a powered z-wave door sensor with backup power supply. (extender function not available)
What do you think ?
Thanks
Chris
