* I have 1 temperature sensor only reading as one but all the rest works
* This works on my mobile connect to your network then use the ip you supply DEVICE IS ON FIXED IP

Wireing to new pcb all relays are on by default so reverse on off
temperature sensor is on D4
Relay on D0 is 16
Relay on D1 is Led 1
Relay on D2 is Led 2
Relay on D1
CHANGE THE TEXT ON THE WEB PAGE TO YOUR REQUIREMENTS WITH CARE
This works 100% with TWO led connected to port / pin 4 & 5
Temperature reading from port 0 (ONE PROBE ONLY)
