Adding Door sensor to Multisensor not working...
-
Greetings All,
I previously had a working sketch for a multi-sensor. I have since tried to add a door switch to the sketch but i can't get it working at all. All the other sensors seem to be working. Any advice you can provide would be greatly appreciated.

BUTTON_PIN
Are you trying to add a motion sensor or a reed switch? What is BUTTON_PIN?
What is the log saying?
Try to substitute the followingsleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), CHANGE, SLEEP_TIME);with
sleep(DIGITAL_INPUT_SENSOR-2, CHANGE, 0);

Thanks for the response. I should have been more clear. I currently have motion, temperature and humidity. I am trying to add a reed switch to use as a door sensor.
With the code a I posted above motion temp and humidity all work fine but I cannot get any output from the reed switch. I have tested the switch itself and it is fine, so I know it is my code. I am not much of a coder so I mostly sticking stuff together from the examples and trying to learn and improve but I really don't know what I am doing.
BUTTON_PIN I believe is where i define which pin on the Arduino to connect the reed switch to.
The serial output shows that the reed switch registers with the gateway and I can see it in Home Assisstant, but it never updates or outputs anything in the logs again after this line:
189 TSF:MSG:SEND,233-233-0-0,s=4,c=0,t=0,pt=0,l=0,sg=0,ft=0,st=OK:
I made the change to the code as you suggested but it didn't seem to any effect, positive or negative.

Hi!
This is how I see it:
You sleep most of the time so both the motion sensor and the door sensor will have to generate an interrupt in order for the sensor to transmit.The Arduino only has two interrupts, 0 and 1. Pin 2 generates interrupt 0 and pin 3 generates interrupt 1.
The motion sensor is attached to pin 3 which generates interrupt 1 (3-2 = 1) but only pins 3 and 2 are able to generate interrupts. You have attached your door sensor to BUTTON_PIN = pin 7 but pin 7 cannot generate an interrupt. This is why you never see this triggered.
Try attaching the door sensor to pin 2 and re-use the code for the motion sensor, transmitting the message msgDoor.
You will have to change the sleep message also to handle two interrupts. This is the constructor for the sleep message, taken from the 2.x API-definition:
int8_t sleep(uint8_t interrupt1, uint8_t mode1, uint8_t interrupt2, uint8_t mode2, unsigned long ms=0);

Thanks a lot everyone for the responses. I have got a little further. I am now able to get readings from the door sensor...sort of.
Everything works fine with the sensor if the door switch is close. As soon as the switch is open, it flips to open the close over and over again a spams the gateway with the messages.
Here's what I've got for code. I suspect maybe something is wrong with the loop.

@shadex12 see if setting the door sensors to INPUT_PULLUP instead of INPUT helps.
My guess is that the pin is floating.
Edit: sorry, I see now that the pin is set to high which does the same thing as setting pullup. Ignore my advice

Okay I figured this out!
The problem was actually with where I was defining the pins. They where withing the if statement for the DHT warning. I have moved them outside that statement and it seems to be working fine.
