the 100% State of Charge on the Chargecontroller is confusing but represents that the current voltage could be nearly 100% SOC on a LIFEPO-Battery and the Charge-Controller does not see Energy going out.
Since the Charge-Controller DC-Out is capable of 30A output (26V= @30A ~700W) i consider connecting the inverters directly there… then the controller also can calculate state of charge knowing how much energy went in and out.
uses bluetooth to scan the immediate surround for blue tooth-enabled BMS and chargecontrollers by Powerqueen
reads data every 5 minutes and stores it in a database
offers a web-dashboard, showing the current data and a history-graph
offers a kiosk-dashboard for a waveshare display on a raspberry-pi
gives you an admin-dash for configuration
– network-settings
– up to two webhooks to send the data to
– on/off for api-access to read the data from the box
does not “write” to the hardware
Prerequisites
Powerqueen Batteries or Charge-Controllers
raspberry-pi
ssh access
bluetooth-dongle (since the raspi-bt is not stable)
waveshare display
setup raspi with drivers
Complexity
Power-User proficient with the command-line
Showcase
This is a vibecoding effort with heavy human oversight.
It shows a path to more accessible hardware wit a little help of the AI-friends.
Now you!
Testers
Who is willing to test the software before i put it on Github?
