[SOLVED] Switch cotrol + openhab

[mihai.icey.ro]

Hello,
First of all, I wanted to say that I am new in "smart-house" family... I am doing this to learn new things and they are awweesssommee

I managed to make a hardware lamp. It's an esp8266 esp 12 that controls a light. with ESP Easy 120.
I have some problems here.

I managed to make the configurations for the relay. On GPIO4 (lightSwitch) I have the Switch for the lamp and GPIO5(lightState) is the relay, settings are from this video: https://youtu.be/Kp4KJVbOWd0.
The Rule is this one:

Code: Select all

on lightSwitch#Switch do
	if[lightState#Switch]=1
		gpio,5,0
	else
		gpio,5,1
	endif
endon

If I push the button the light goes off, if I push the button again...it doesn't come back.. I don't know what to do in this case.

The second thing, how can I add a digital button to my openhab sitemap?

I google it both things but I don't know how to really search for them...

Thank you

P.S. the relay it's like the one on the picture attached

ESP8266 works with 3.3V and the if the relay works with 5V, you need a resistor divider.

Code: Select all

ESP8266 ESP01 - light switch

Define device one as Switch Input, Push Button Active Low, pullup on, GPIO 0. Name it pb01. Name the value #1 as value.
by hardware - gpio-2 - output high - for relay  - gpio-2 low triggers relay
              gpio-0 - input

rules

// pb01   - gpio 0 - D5
// output - gpio 2 - D3
// boots off

On System#Boot do
// GPIO,2,0
endon

on pb01#value do
   gpiotoggle,2
endon

on pb01_on do
  GPIO,2,0
endon

on pb01_off do
  GPIO,2,1
endon

on pb01sw do
  gpiotoggle,2  
endon

this works for me.

Sorry, i forgot to close this topic.

I used an NPN Transistor (NPN 2N3904) for controlling the relay, and I used these schematic.



Thank you
