Hi i’m looking if someone tried to build his own Fibaro Multisensor?
Many have build a NodeMcu multisensor, but they are working on USB power.
I would like to built a multisensor running on a battery or batteries (at least for a year).
So actually a diy fibaro multisensor
All the tricks to getting low power consumption including the circuit diagram are available. There’s even a video that explains how the circuit gets a longer theoretical battery life than the self discharge of the battery:
You can use these design notes for your own device.
