Hello

The PwrTool 500 is an open source, hackable power shunt for integrating battery and DC load metering into Home Assistant. It is the first in a range of products using our recently released FLIP_C3 mainboard which integrates an ESP32-C3 and 50v+ tolerant buck converter on a compact dev board. Our default firmware is ESPHome, but you can put whatever you want on it.

The PwrTool 500 was created by Chloe Madison, a Bay Area artist and industrial designer operating under the brand Voidbox Industries, or VDBX.io - It came out of living full-time in a bus and finding the need for better open hardware that interfaces Home Assistant with off-grid battery systems.
