Need help to convert Celsius to Fahrenheit

I thought I saw a sampling some time ago, but am not having any luck to find it now that I need it

I want to convert an Indigo_var_celsius to Indigo_var_fahrenheit

I used to convert in my App but since I moved away from that I want to do it in an action using applescript or python.

A pointer to where I can find a sampling or a sampling is very much appreciated.

I found this python code with a quick search:

Code: Select all

fah = (cel * (9.0/5.0)) + 32

Thanks Jay,

Time to jump into the Python pond

C'mon in - the water's fine.

Actually, that line of code would work in either Python or Applescript; the differences are all in getting "cel" out of a variable string or device state and then trimming/rounding "fah" and getting it back into a string to store and/or display.

Survived my first "swim".
Perhaps not the most stylish, but it works

Code: Select all

celsiusVar = indigo.variables[26618308]
tempVar = celsiusVar.getValue(float, default=75.0) # Alarms as HOT if it can't be converted
indigo.variable.updateValue(836995441,str(tempVar * 9/5 + 32))
indigo.variable.updateValue(894772009,str(tempVar * 9/5 + 32))


Thanks for the "push" Jay.

BEWARE: Fibaro advertises on their website and on the product boxes for the US versions of the FGK-101 (door,window, and temp sensor if you ad the DS18B)
and the new FGMS-001 Motion Sensor (motion, light, temperature) that they display Fahrenheit. This is TOTALLY FALSE!
FIbaro is misleading US customers with this. When contacted, they said they "assume" you are going to use
"their" home automation control unit, (instead of Indigo).
BUT, note, the actual devices listed above will ONLY display in Celcius to Indigo. The only option we have is to use a
Python Script in Indigo to do a conversion and send it to a Variable to get Temp readings in Fahrenheit.
The Python Script conversion works well
BUT, that will only put the converted Fahrenheit reading in the Variable window, it will NOT display
in Fahrenheit in the main Indigo device window. (it still shows in Celcius there).
Fibaro has been called out on this misleading advertising for their so called "US versions" of these sensors, but they
still haven't changed the sensor's code or their misleading advertising to US customers. .
Fibaro needs to do the right thing and set the "US version" to display in Fahrenheit, so Indigo doesn't have to "fix" their problem.

Yeah, the motion sensor is really nice and inconspicuous, but the Celsius-only reporting is an annoyance.

Sounds like a plugin might be useful here?

Create a plugin temperature device, select any device in Indigo that supports temperature (C or F) and trigger on any update, and update the state of the device including display value to the opposite conversion.

Use this device on control pages and further triggers instead of original or variable.

As useful a plugin/script would be for this kind of scenario it'd be lovely if it were just baked into the indigo UI... A global preference for F or C.

Or of course just get everyone to use C° . *flees*

Hehe!

I agree, but it's not gonna be in 6.next which is coming before 7.invented

Should we all settle on degrees in kelvin?

How about Romers? That's a measurement of temperature isn't it?

I agree that Celsius is by far the most logical and best choice

However, we do get confused in the UK

For those of us in the UK: Do you notice how the UK Newspapers always use centigrade when it is going to get cold (e.g the temperature will drop to -10 in Scotland ) but when it gets really hot they use Fahrenheit (e.g. the temperature will hit the 90's on the South Coast)!

Yeah I've noticed that. Of course we aren't completely metric.. We still use miles for distance. That needs to change.
