Thanks for the reply koffienl
I get the general idea, where I struggle is the specifics. Below is a screenshot of what I have now:
What I like to accomplish is to have the “Heater” turn on when the “Salt Water Tank” temperature goes below the set temperature in the “Salt Water Tank Thermostat”. At the moment I have a fixed rule setup to do this at a hardcoded temperature of 28 Degree, not using the “Salt Water Tank Thermostat” setting.
I need help with the exact syntax for the rule based on my config.json.
Here is my config.json:
“plugins”: [
{
“plugin”: “cron”

“plugin”: “mobile-frontend”,
“customTitle”: “Chrisi’s Command Center”

}

}

}
}
],

{

}
]
}
Thanks!
