DIY Fibaro Multisensor

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 :stuck_out_tongue:

Anyone has some experience on this?

You can use these design notes for your own device.
