Sensor dht+relay won't send data or present

gohan

On my Domoticz the dht11 shows as a combined temphum and it shows both data even if I present it separately

MasMat

I think there's a bigger clitch in my code somewhere that is causing that. I'm not sure if the millis-timer is properly used here or if that is somehow interfering with the other code.

gohan

I'd use a wait (500) or (1000) at the end of the loop, to slow things down a bit

MasMat

@gohan you mean "delay(500)"? Will that not affect the radio function if it is waiting for a command for the relay for example?

MasMat

The startup serial "seems" OK, but the relay function is not there. The MQTT log appears to send empty strings "" rather than 0 or 1 when I attempt to activate the relay from Domoticz.
Just in case, the startup serial is as follows:

@MasMat said in Sensor dht+relay won't send data or present:

@gohan you mean "delay(500)"? Will that not affect the radio function if it is waiting for a command for the relay for example?

That's what wait() is for (mysensors specific) , it will not interfere with the radio commumication.

MasMat

Thanks for the tip. Good to learn these things as I go.

I'm to the point of rebuilding the sensor (or building a duplicate really) to see if this could be a hardware glitch.

gohan

You could try ethernet gateway instead of mqtt if it works better and move to mqtt later on

MasMat

@gohan I cant see the upside to going back since I couldnt get the Ethernet gw working but the mqtt appears to be working AND Domoticz supports it apparently.
I did a quick breadboard setup and it seems the problem might be hardware rather than sketch.

Question about the wait command: could I use wait (=soooo simple) rather than a millis timer to have a sensor/node be ready to activate a relay at any time but to only send DHT data every 60s or so?

gohan

sure you can use the wait()

MasMat

To follow up. It was hardware: broken vcc pin on the dht11 corrupted the whole sensor code badly. Resolder and added wait-code, inverted the on-off 0-vs-1 and I have a good working sensor. The duplicate is also installed and working reliably.
A 6-relay board is also working nicely and Domoticz is great. My old system is nearly replaced and I couldnt be happier.

Respect and thanks all around!
