How to add external power supply #13

Hi! I have this since some time now and I can't be happier! I really love it. I'm capable of soldering and tinker with it, in fact I nearly kill the board when it first arrived because I shortcircuited by accident, then I had to replace a path with an external wire! |

for modification you need to remove the D3 and D2 diodes, then connect the trace from the doorbell sensn "OPT" to the free pin on ESP like to "LATCH" pin, basically from D3 pad to D2 then connect EXT-Trig to the battery terminal, then you can use ESPHOME for firmware use ESPBell-Lite example and change pins in configuration, battery terminals can accept 5v.
