Not MySensors, but related. Power over Ethernet (802.3af compliant) addon for the raspberry pi zero. I plan to use this for high power & high reliability devices where wireless will not work.
Top one is a higher power version, bottom one just uses an off the shelf regulator.
Currently these just have some IR LED's to control IR devices.
I soldered together the PCB I made for my RFM69 Pi Gateway. Next step is to put it in a nice enclosure
@Nca78 I will be sure to do that when it's done, it's still a little rough around the edges

Was going for a bed occupancy sensor, but I got a pretty decent scale out of it, it is sensitive enough that it registers if I put my water bottle down on the bed.
@martinhjelmare Good eye! I can't believe I missed this. Thank you. This solved my problem.
I look forward to using this in my home automation setup
@manutremo Thank you for that info-graphic. You are and @gohan are correct, I have an RFM69W. This is what I get for buying from the cheapest seller on eBay
