Help with momentary relay for Garage Door controller?

#1 Post by TommySharp » 12 May 2018, 03:32

Hi everyone,

I have a garage door where it can be activated by momentarily closing a circuit.

I'm trying to do this with a Wemos D1 Mini and a relay board. I need the relay to "close" for 500ms and then open again.
Is anyone able to suggest how I can do this easily within ESPEasy?

I was hoping to control it via MQTT just like I am querying the open/close status of the reed switch connected to the same Wemos D1 Mini.

However it looks like this HTTP call works well enough and sets GPIO5 to high for 500ms and then turns it off again.
Should work perfectly for my use case.

I haven't used MQTT yet but I'm fairly sure it can do the same thing. No doubt someone will come along here and offer some help along those lines. :ugeek:

You need to declare a device only when you want to know the state of the device.
For output only you just pulse the GPIO since you don't care the state after.
