DC Power Meter for Battery Monitoring using BT-DCPM and Rpi 3

Post by MobileDomUser » Sunday 20 May 2018 8:57

've been working on integrating a DC power meter for monitoring my battery into a Domoticz install for our RV which runs on an Rpi 3. Attached is the LUA script I've developed. Here's some information on how to use it:
You can purchase a BT-DCPM from https://www.thornwave.com/products-btdcpm.
After you install it with an appropriate shunt on your battery-based power system, configure the monitor using Thornwave's app for your particular battery type and size. Then follow the instructions at the top of the script to get Bluetooth running and add your sensors to Domoticz.
Here's a screenshot of the Utility sensors:

Nice!

The connection is via Bluetooth to the RPI?

Sorry for the late reply, evidently I don't have my notifications correct. Yes, it is Bluetooth.
