Hello all,
I have a node to wher a dht22 is connected and a relais, this is to sitch on or off my fan in the bathroom. Before openhab i was using pimatic and that was working good i could see the temperature and humidity and i could turn on and off the relais. No with openhab i get the temperature and the humidity in the inbox but not the relay. Is it somehow possible to get this working?
Greetings, Martijn
@rejoe2 said in Relay not reacting first 3 seconds:
AVR board definition
If this is the problem then could i do something about it?
Hello all,
I have the following sketch working with a pimatic installation. When i switch on the relay nothing happens
when i keep switching it on and off than after 2 or 3 times it starts reacting. But every time i wait a couple of seconds
i have to switch it on and off a couple of times before it reacts. This is th epimatic log output if i switch it on the first time.

No it doesn't do that. If i switch on the relay in pimatic then it goes on.
if i then rebot the node the relay stays off but the status in pimatic also changes to off.
@blacey You mean like this?

I did not get it working the way i would like. I now used a different sketch.
here i had the same problem but i just set the relay_OFF from 0 to 1, and the Relay_ON from 1 to 0
And with this sketch it worked fine.

@blacey where should i put the code in your post?
The node is working. The problem
Is that when it is connected to the gateway then the relay gets turned on but The status in pimatic does say it is turned off.
The sketch works, but i still need the relay output inverted.
Changing the values from relay_on and relay_off does not do the trick
I reversed the lines and changed the values of relay off and relay on but that did not do the trick.
This sketch i copied from a other project so i don't really know why debouncing is implemented.
The example you scribed is exactly how it should work.
