Firmware for esp8266?

Question

Do it yourself

Please tell me the firmware for esp8266, on which it would be possible to dynamically (web-muzzle, some protocol) set up an autonomous operation logic.
Those firmware that I have already seen (espeasy, sonoff-tasmota) only support online control from an external source (domoticz, openhab). To me, to control the boiler, I need firmware with autonomous control, which independently makes a decision to turn off / off the relay based on the values ​​​​of the temperature sensors and the specified parameters.

Answer 1

Quite by accident I discovered that espeasy supports the simplest scripting language , this option is disabled by default.

on boilerCold#Temperature do
    if [boilerCold#Temperature] < 26
        gpio,12,1    //relay
        gpio,13,0    //led
    endif
    if [boilerCold#Temperature] > 28
        gpio,12,0
        gpio,13,1
    endif
endon

Answer 2

I think it's easier to use nodemcu lua
there, the file system and the LUA 5.1 interpreter
, the code is launched from files, and knowing the logic of work, you can describe all this in a programming language.
The entry threshold (minimum amount of knowledge) for LUA is lower than for C ++,
you collect here https://nodemcu-build.com/ choosing only the necessary modules, there is also documentation on them. For any DS18B20, there are ready-made libraries both in LUA and built into the firmware written in C ++.
It is better to use the firmware with Float (usually 2 versions come from the site to the mail).
