![]() Set all pins to disabled, except UART, which is left as normal.īaud set to 9600 (despite the Powermaster being a v18 firmware panel)Ĭonnected TX to RX, RX to TX, GND and 3.7v to the end 3v pin/GND on the NodeMCU ![]() Set a static IP on the device and connected it to the same Wifi network Homeassistant is on I found the easiest way was to connect it to the Pi I run HA on. Having got nowhere, except many hours of troubleshooting adding/removing integration, trying 2 different wemos boards and two different powermaster 30 panels, I ordered this NodeMCU, another panel and followed the helpful wiki ( Using NodeMCU PowermaxProModel6 I also tried using a step down interface to manage the output voltage, but just saw crc errors in the HA logs (and the integration still not working). connecting directly to the tx/rx on the panel will either not work for long or (most likely) damage the visonic panel. I opted to power the device using a power cable spliced into the 12v supply for the board. Opting to use a Wemos for the easy way to connect relays for siren etc may not be a good idea for this panel. ![]() I have the panel now registering and working!įor the benefit of everyone else, here are my findings ( for a Powermaster 30 panel ). ![]()
