Ordered 3 of these and installed 2 immediately without issue. Had some trouble with the third but Mike was super responsive via email and helped me troubleshoot the issue, (which wasn’t from the GRGDO1 at all, but poor installation of the sensor wires from my garage door opener). Once I corrected that wiring problem it booted right up and has worked flawlessly since. I would recommend the GRGDO1 and Mike’s customer service any day. A much better experience than dealing with the other sellers in the RATGDO space!

Ordered 1 of these and it was DOA, however contacted Mike and he was super responsive, and I received a new unit in short order. The new unit was super easy to setup as per instructions. Works flawlessly with my New Chamberland garage door with the rolling codes. The GDO1 exposes all aspects of the door motor, lights, and sensors and exposes those sensors to ESPHome, making it easy to automate. Mike’s customer service is above and beyond and I would highly recommend ordering from him.
