DS18B20 Sensor on heating forward -------> Device with on or off

Jens

Hallo Pimatics,
i need help for my project. I have 12 Temp-DS18-Sensors on my PI - Pimatic.

My question: How make i a device with off or on/ blue or red output (usage heat no/ yes),
for example: under 30°C -----> off, over 30°C-----> on.

Greats & Grüße from Dresden.

You could create a new device HeizungAn(DummyPresence) and create a rule which will set it.

when 
Temperatur of EG VL Bad is < 30
then
set presence of Hezung An present

If you want to use it as an indicator that the heatin is on if the temperature is under 30 degrees

If you want to use it to control the heating I guess a Switch instead of a DummyPresence sensor would be better.
You could then ad rules which control what happens if the button is turned off or on.

Sometimes it could be so easy

{
  "id": "kontrolllampe",
  "name": "Kontrolllampe",
  "class": "DummyPresenceSensor"
}

My Rule:

{
  "id": "temperatur-lampe",
  "name": "Temperatur Lampe",
  "rule": "when temperature of Raumtemperatur <= 20 then set presence of kontrolllampe present",
  "active": true,
  "logging": true
}

Thanks a lot

Hallo and Thank you. It works with small mods very fine.

My DummyPresenceSensor without autoreset.

{
  "id": "my-sensor-led1",
  "name": "EG Bad",
  "class": "DummyPresenceSensor",
  "autoReset": false
}

Two rules for preset and absent.

{
  "id": "eg-bad-led",
  "name": "EG Bad",
  "rule": "when temperature of my-sensor1 >= 30 then set presence of my-sensor-led1 present",
  "active": true,
  "logging": true
},
{
  "id": "eg-bad-led-2",
  "name": "EG Bad 2",
  "rule": "when temperature of my-sensor1 < 30 then set presence of my-sensor-led1 absent",
  "active": true,
  "logging": true
}

And in Pimatic in function!

Thanks & a nice Weekend!
