Thanks Gelidus Research for a great product at a reasonable price!
I ordered this and when I tried to set up my board, I ran into a problem setting up the firmware (which was my first ESPHome project). Mike from Gelidus research was super responsive and helped to diagnose the problem. Turned out I had gotten the board into a bad state by not following the steps (hint: you may need to set up SSL for your HA instance). Mike immediately sent me a replacement board, which worked perfectly after I got better wifi in the garage. Integration with my liftmaster opener works beautifully, and I can control the opener with Home Assistant without relying on a cloud service.
Thanks for a great product, for the great support and for standing behind your product Mike!

These devices are a near-perfect mixture of turnkey and hobby – the documentation is top notch. The product is ready to go right out of the box and ready to hook up and it’s overseen by someone engaged and seeking continuous improvement. Highly recommend purchasing any of these devices!
I do own one of the “RATGDO Board v2 USB-C” devices, I purchased a 12v to USB-C voltage converter such that I could tap my openers 12v battery and power the RATGDO device without using the 120v power socket.
