ESP8266 Community Forum

- Thu Oct 13, 2016 6:01 am #56456 Hi Folks
Have started working with home assistant and would like to make a couple of custom sensors/devices to integrate.
I dont have an electronics background, but am geeky enough to sort out most things with a bit of help

My garage door controller has a couple of terminals that allow me to control it.
Eg, it has a single switch with a pair of screw terminals (control/ground) that once shorted, the roller door rises/closes.
It also has terminals to control the up/down/stop function specifically as well.
Tested today, shorting the single switch will give me what I need.

Hoping I can program up a 8266 with ESPEASY to allow me to do this. Question is, will the 8266 natively allow me to do this, or do I need a relay? I just need a way to short the two pins...

Thanks all!

But I caution you, that this is probably not a project for someone who is inexperienced in electricity. You are asking to control a high voltage, high current device without the knowledge of what can and can't be done. Motors and relays don't easily mix. Probably I am over cautious because the switch voltage is most likely already stepped down to low voltage and probably controls a relay already which should already be properly configured to control a motor. But, without schematics, I would not be able to guide you, other than to caution you to gain a little more knowledge and experience before experimenting with controlling high voltage motors.

I don't like squelching curiosity and initiative. But, I think this is too big a step for the inexperienced. You could try to learn to control a low voltage motor with a relay first. There is plenty to learn and have fun with there without the dangers high voltage presents.

Just my two cents. Good luck and have fun.

A little knowledge can be dangerous sometimes. You just may be geeky enough to burn down your house.

Understand if I came across like that. I have an understand of power and electricity, where I dont have experience is with these chips. I've ordered a few to tinker with.

The roller door diagram is attached - the interfaces shows a few options for external connections based on requirements. For what I need, just a single momentary switch (SPST).
