This was kind of a side note in my home automation project that seems to be an issue. Lots of Pi’s are being used as the controller/server for automation software and the easiest way IMHO is to run them headless and probably in a remote location like a closet or server rack. You have to start thinking about powering the little booger up and the options are relatively decent but stuff is getting more and more murky. I have POE switches in my network so grabbing power that way made sense. September of last year I bought a Navolabs POE hat but didn’t realize that it would only work on a 3B+ so my 3B’s wouldn’t work. So, last week I bought a 3B+ and swapped the SD out of my working OpenhabianPi. The hat works great!. I bought a case with a small fan in it and had to modify it so the hat would fit but it powered up and all seems well. I went on to Amazon to look at other hat options for my 3B’s and found that the NavoLabs hat is unavailable and that Navolabs website has done dark. Wonder what happened.Seems to be an awesome product and the reviews are all stellar.
The Raspi official hat seems to be having issues with power smoothing. There are external adapters for POE as well that I have looked at with mixed reviews. I have also had lots of problems with wall wart supplies saying they are rated appropriately but have fallen far short of needed limits. I just bought a PWR+ wall wart that I will be trying on my Pi that is home in my toolbox at work. Yep… toolbox with computer and internet I am hoping that this one will actually power it without issues.
