Switching a boiler on/off from ui
With the use of a botton on the dashboard I trigger a trigger node wich remains high for 45 min wich trigger a gpio pin on raspberry for this time.
the inject node is to initialise the text on startup off the flow.
My warm waterproduction is programmed with simple timer in the evening but when we want hot water during the day I can do this via the dasboard without descending to the basement to flip the the manual switch on the timer.
