Script that compare temperature reading from two sensors

Have installed a series of Aeotec "Multisensor 6" throughout my house (internally & externally), I also have a series of high windows fitted with Fakro window winders.
I'm trying to create a trigger that will automatically open all the high windows when external forecasted temperature (using Cynical Weather) is above 26°C, and the current temperature from the external Multisensor 6 is below the temperature from one or multiple internal Multisensor 6's.

Does anyone know how I have compare the temperature reading between the two Multisensor 6?

Are you on Indigo 7.4? If so, create a trigger with the following condition.

[If Python script returns True:]

Code: Select all

outside_temp  = indigo.devices[12345678].states['sensorValue']
inside_temp   = indigo.devices[12345678].states['sensorValue']

return inside_temp > outside_temp


Should work. Obviously, you'll need to replace the device ID numbers with your own (be sure to use the ID for the temperature device and not the motion device, etc.).

If you're not on Indigo 7.4, you can still do it--but the process is slightly different.

Thanks Dave, I really appreciate your help on this.

Given that the Multisensor picks up six different variables, including temperature. How does your script know to select temperature?

Can you please point me to the Device ID # is should be using to make this work, from the info below.

The Multisensor 6 picks up - Temperature, Humidity, Luminance, Ultraviolet light, motion & tampering. I just want to focus on temperature.

When you sync the Multisensor 6 to Indigo, Indigo creates six linked devices (one for each type). You need to specify the device Id of the temperature device.

Right. Find the temperature device in the Indigo device list, right click on it and select "Copy ID". Paste that in place of the dummy value in the script above.

Thanks guys, I hide the Device ID # in the device list, I think I have managed to work it out.

Thank you for your help.

Glad you were able to do what you needed.

Further to this scrip inquiry, I would like to add a condition that needs the internal temperature to be greater than 19°C

With your assistance, I have created the following, but I'm not sure how to add a greater than clause, see blue writing below..

outside_temp = indigo.devices[209400252].states['sensorValue']
inside_temp = indigo.devices[1450104654].states['sensorValue']

return inside_temp > outside_temp
indigo.devices[1450104654].states[19]

Any help would greatly be appreciated.

I'm not entirely clear on what you're trying to accomplish, so I'll take a guess.

Code: Select all

outside_temp = indigo.devices[209400252].states['sensorValue']
inside_temp = indigo.devices[1450104654].states['sensorValue']

if inside_temp > 19:
    return inside_temp > outside_temp


But I'm not certain that's what you're after. If you want the condition to be 19 or greater, change the ">" to ">=".

You need an else clause and another return statement. Probably just "return False". That may be the default in Python, but much better to do it explicitly so you don't wonder a year from now.

+1 - for Python condition scripts, you should always return either True or False.

Good call. The first script would return True or False by definition, but my revision wouldn't without the else.

Code: Select all

outside_temp = indigo.devices[209400252].states['sensorValue']
inside_temp = indigo.devices[1450104654].states['sensorValue']

if inside_temp > 19:
    return inside_temp > outside_temp
else:
    # uncomment one or the other.
    # return True
    # return False


Just to clarify, I want to create a condition that checks the internal temperature via a multi-sensor to ensure it is greater than 19°C, before comparing the internal & external temperature. If the external temperature is less than the internal temperature, open all motorised windows.

The trigger here to to check the forecasted temperature for the following day is going to be greater than 26°C

I cut & pasted you script below into into my trigger event, and I got a message "embedded script: expected an indented block". Can you please advise what this mean?

It means you have the indentation in the script wrong. Python is very dependent on correct indentation. On the other hand, the sample script posted above needs to have ONE of the last two lines uncommented to work. If they're both commented out, then you have no executable line after the else statement, which will give the same error.

I think you need:

Code: Select all

outside_temp = indigo.devices[209400252].states['sensorValue']
inside_temp = indigo.devices[1450104654].states['sensorValue']

if inside_temp > 19:
    return inside_temp > outside_temp
else:
    return False
