I have been living the free life of a rover for the past 7 years inside my truck. Though I try my hardest not to let Life intrude into my Hobby time, alas, sometimes it must.

Despite this I built a Raspberry Pi based openHAB system which I got to operate all my lights and monitor Temperature and Humidity.  It worked very well.

I hit a snag when I started trying to get it to monitor battery voltage and current. openHAB looks pretty and seems geared towards proprietary components.  Once I started to try to get it to talk to hacked together DIY gadgets the whole thing seemed to be too high level.

I found myself in Darwin during the Wet Season where water molecules penetrate 3 mm of aluminum roofing through some sort of monsoonal Quantum Tunneling effect. When the DHT22 started registering a Humidity of 300 percent I knew something must be wrong. Then everything blew up!

Now it is time to have another crack at it.

Plodding along nicely with my new system.

I have the relay board installed and working.

Now learning Node Red to get it to do what I want it to. I am getting alot more done much more quickly than I did with OpenHAB.

USB Power Modules - Fault

 
These cheap and cheerful USB 6 - 26 volt power supplies wont boot a RPi. The green POST just flashes on and off. I got it from Bangood.
