motion and relay

[dias]

hello, I am looking for a code used 2 motion sensors and 1 relay
is that someone saw this forum? I have do a search but I found nothing

[Dalhoj]

Hey maybe you can modify this sketch:

http://forum.mysensors.org/topic/902/relay-motion-multisensor

[dias]

I have modified the code, I have no error message but:
the relay remains on position but n not appear in domoticz
in the logs they have the same name
dth11 the works

@dias You're presenting the relay incorrect.

this line in the setup

gw.present(CHILD_ID_RELAY, V_LIGHT);

needs to be

gw.present(CHILD_ID_RELAY, S_LIGHT);

And then you should see the sensor in Domoticz

[dias]

the relay is present in domoticz but not the more it is driven on position when I connect the Arduino
the motion sensor works well but they have the same name in domoticz so that I have one that appears

[TheoL]

@dias I'm sorry but I really don't understand what you mean. Try to insert some Serial.println("") and check the serial monitor. That way you can debug your sensor.

[dias]

I use google translation
the relay remains stuck on walk
2 pir sensor works well but in domoticz with the same name

[TheoL]

I think this might cause your problem. It's in the incommingMessage method

 if (message.type==V_LIGHT) {
     // Change relay state
     digitalWrite(message.sensor-CHILD_ID_RELAY+RELAY, message.getBool()?RELAY_ON:RELAY_OFF);
     // Store state in eeprom

I think you copied it from the multiple relays example.

try changing that code to

 if (message.type==V_LIGHT) {
     // Change relay state
     digitalWrite( RELAY, message.getBool()?RELAY_ON:RELAY_OFF);
     // Store state in eeprom

In your code, you are not writing the value to the pin you've assigned to the relay.

Thank you for your help
it works for relay and dth11
always the same pir sensors

[dias]

on the picture have there a motion sensor that appears
