Hi all, I ordered a [Door Lock from AliExpress] and from what I see on the pictures I could use RF and with a Gateway sniff the command to use it in HASS.
But instead I want to connected it to a relay connected to a Nodemcu and use MQTT to open the door.
From the pictures it seems you could easily connect a relay in place of the push-button input and use that to fire it. That might only make it unlock for a little while though. It doesn’t seem to say whether it’s made for impulse switching or just a firm on/off connection.
Of course you will need appropriate firmware on the NodeMCU, either self-programmed or something like EspEASY.
