My first Cayenne project - just to get to grips with how everything works. Simple temperature sensor that sends an email notification if the room temperature is not suitable.
What’s Connected
Arduino Uno, W5100 ethernet shield, DHT11 humidity and temperature sensor, breadboard, jumper wires
Triggers & Alerts
One that triggers when the room temperature is below 59F, one triggers when above 72F. Both send emails to me.
yes i find some and used some but i cant figure out why my DHT22 dont working. I know its working by monitoring serial port but i dont know why it dont show temperature in cayenne. Thats why i asking
What i did:
connect DHT22 to +5/GND/DATA PIN8
used DHT_Cay.txt code and modify port and DHT version in code - upload
cayenne - add custom widget - value - set I/O digital pin8 - set data to temperature.
finally i manage it to work but it was weird…in web app it show me 0 …but in mobile app correct number 22C…i had to switch Farenheit to celsius and vice versa to get it working… as bonus my BMP180 is showing correct in app but showing nothing in web app (browser). Its know bug?
