Hey Kcest

Nice work!
Can you help me if I would like two PIR sensors in the same sketches.

thank you in advance, Tom

Hey Hek

Thank you for your good advice. I have a little vacation here in Easter. so I got it to work with 2 door sensors maybe it's not the best looking program . but it works .
Where can I learn more about these lines, I do not understand 100 % yet :

Bounce debouncer1 = Bounce();

debouncer1.attach(BUTTON_PIN1);

digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);

Thanks for the help .

Is there anyone out there who just want to give me a hand by getting this skeleton to work. I will be very happy just a little help. It could be great.

Hey Hek

Thanks for a really exciting home page , I really got interested in building a sensor myself just need some start help.

I've tried to build together a relay and door sensor program from Hek one cloned program without success. I have a vera light. but I'm new about building sensors. Are there some who will look at the program and see where errors.

What I see in vera is only one door sensors and 2 relay, where there should have been 3 door sensor. I use a Nano with series connection to vera.

Hope some one can help me, last 3 weeks I have tried unsuccessfully various changes.
