Just received and installed the ratgdo 2.5i board and I'm thoroughly impressed so far. I've got way more control over the door than before (using a ZEN17, 1 tilt sensor and 2 contact sensors previously) and it was a breeze to install.
I am running it through HA, so if you are as well, I highly recommend it. Alternatively, you might try the MQTT integrated app floating around here as well.
If I were ask for anything, it would be for him to go back to using boards compatible with off-the-shelf NodeMCUs. I have a bunch of those and could flash a new one in a pinch. Also, I have questions about the longevity of ESP8266s in general.
