I have the following set up between a nano and the ESP-8266:

VCC-------->+3.3v
If that's ESP8266 VCC to Nano 3.3V, be aware that the nano 3.3V regulator is not powerful enough to power an ESP8266.

If that's Nano VCC (5V!) to ESP8266 3.3V, that's just wrong and has probably fried your ESP.

No, i had heard of those issues before. It id 3.3v external power. Not power from the nano. I have double checked and it is supplying 3.3v. We 3.28v but close enough.

Hi

can anyone help me with a "small" project?

i want to create an thermostat for an electrical heating control.

i found almost what i wanted in this code here: https://github.com/mharizanov/ESP8266_Relay_Board

the only thing missing is a push button that allows to override the normal target temp to something else for a set period of time


its intended for a flat where an autism person lives along with the care taking staff


the last group (staff) has a very bad habbit of messing with the panels and it tages ages to set the dials etc as the other flats give of heat too

my plan was using the firmware above and then if the staff should feel cold they can push a button to get extra heat for say 15 mins
