Valve and IrrigationSystem

Based on this great wiki post. I have LC Tech 4ch relay (esp8266) running Tasmota and the article above does not fits my needs (no OpenSprinkler device or software).

So here is my workaround (heavily commented) with fully working timer.

I’m not so good in nodered so any comments or suggestions will be appreciated =) For example in this case I should repeat this code 4 times for every valve and change global variables to Valve(1-4) and this is annoying.

I found IrrigationSystem in HAP-NodeJS (and NRCHKB too), but no idea how to make it work. This is simple empty icon with no input and output, how to put my valves to it?

One button and sprinklers do their program

This “feature” is available from opensprinkler. I just made that one button send an HTTP request that starts the opensprinkler program…

The Home app is only ever displaying what opensprinkler is up to. I run opensprinkler and this homekit bridge on the same pi - I poll the opensprinkler api every second to keep things up to date in the Home app… The output of pressing a Home app sprinkler button is always to send an API request. Homekit has no part in the logic.
