Doorlock project

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.

[This is my relay]
With a NodeMCU

Or I might order a wemo d1 with a relay shield to make it more compact.

My question is if connecting everything straight forward to the Nodemcu will it fire the 12v doorlock to open?

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. :slight_smile:

Thank you for the reply!

I think it’s a impulse switch but I’m not sure.

The firmware I already have from a similar project.
Fingers crossed for it to work :smiley:
