Configuration
1

Hi,

I know this is probably very obvious but I can’t work it out!

I want to make my temperature sensor have a state of on when above 22 degrees.

I have it working on the main page via this code:

#AM2302 Sensor
sensor:
  platform: dht
  sensor: AM2302
  pin: 4
  scan_interval: 10
  monitored_conditions:
    - temperature
    - humidity

I also have a blueprint for nagging notifications that I’m trying to integrate it in to. What I don’t know is how to code it. Help!

That’s not the way it works, the temp sensor will give you a numeric value. From there you could create another sensor that would read on/off depending on the values you set. then that sensor could be used with the blueprint.

template:
  - binary_sensor:
      - name: "temp22"
        device_class: temperature
        state: >
          {{ states('sensor.am2302')|float > 22 }}
  • I am guessing that the original sensor’s name is sensor.am2302 since there is no name configured

Typically you would not create another sensor for this, automations can be triggered by thresholds.

Excellent, thanks. This sorted it :slight_smile:

I just learned there’s a change and figured I’d pass it on since the above is going to give an error in the logs. You have to add a default value for sensor.am2302.

</s> <s>{{ states('sensor.am2302')|float("unavailable") > 22 }}</s> <s>

This will return unavailable if there is a problem with sensor.am2302.

edit disregard.

Are you sure the default is correct? I thought the default value has to be of the same type than the filter it gets used by. :slight_smile:

In this case

{{ states('sensor.am2302')|float(0) > 22 }}

lol yeah it passed the config editor but I know it’s wrong. I’m trying to work it out right now.

Honestly, I have no idea :rofl: I tried to find an answer for myself a few days ago, but couldn’t find anything useful in the documentation and lost motivation… :wink: :rofl:

For now I have set the defaults to a value according to the type and to the threshold, in this case I’d do it like this:

{{ states('sensor.am2302')|float(22) > 22 }}

The problem is that you’ll only notice it’s not working because it’s stuck in one position for a period of time.

@Tap1 you’ll need to use the above example. You will have to choose a number above or below depending on what you want the default value to be, on/off.

Thanks all, I’ve now got this:

template:
  - binary_sensor:
      - name: "Bolier Temp Binary"
        device_class: heat
        state: >
          {{ states('sensor.dht_sensor_temperature')|float(22) > 22 }}
