Control de Caldera Remoto ESP8266 DHT11 + ESP8266 RELAY

Hola a todos!
ACLARO QUE SOY UN NEÓFITO EN ESTO
Luego de luchar durante mas de 3 días y perder el sueño por los enojos y el esfuerzo mental, finalmente conseguí hacer funcionar un sistema de control de temperatura remoto vía wifi (ESP8266+DHT11+Cargador de celular) y un receptor que se encarga de activar la caldera (ESP8266+Relay+Cargaor de celular)

Hi all!
LET ME FIRST BE CLEAR… I AM A NEOPHYTE IN THIS
After struggling for more than 3 days and losing sleep due to anger and mental effort, I finally managed to operate a remote temperature control system via wifi (ESP8266 + DHT11 + Cell phone charger) and a receiver which is responsible for activating the boiler (ESP8266 + Relay + Cell phone charger)

Espero les sea útil como lo es para mi.
Saludos!

I hope you find it useful as it is for me.
Regards!

I have my doubts about this piece of code…

Pete.

I used it to keep track of the state that was comanded from the other side and it can be overrided.

Writing HIGH (which is the same as ‘1’) to an LED widget will turn it on at brightness level 1 out of a possible range of 1-255. This means that the LED widget will appear to be off.

If you’re sharing a project for others to use, it would be helpful to provide details of widgets that are used, and the way that they interact with the project.

Pete.

Dear Peter.
THANK YOU SO MUCH!
Now i know how to solve it! 255 is a great number! lets use it!
now this is a beter LEARNING EXPERIENCE …

This is the Setup i made later and added the EVENTOR to setup the time of the day i want to change the Hysteresis level (temp changes during night are greater due to high wind and windows leaks) this helps to mitigate the heat loss.

There is still an issue left to manage that this eventor thing doesn´t apear to work.
any help is wellcome.

Coming from IOS (there is no eventor) I say code the function into your sketch. :innocent:
