Hello,
I don’t quite see how to pass the setpoint of the "Gladys
I don’t know if this can solve the problem, but to retrieve a value it’s with {{
Thanks @tiboys for the answer.
If I have a thermostat that is referenced in gladys:
the syntax is correct: {{ Thermostat maison }}
I don’t know if I’m talking nonsense but it seems to me that to use the {{ , you first need the action « retrieve the latest state »…\n\nAnd so it can’t do it on a trigger!
I tested it and honestly it seems complicated, actually I couldn’t do it.
So we have to create a scene to retrieve the sensor’s last state and then, we have access to the value in another scene. But then what’s the name of the value?
EDIT : I think I pretty much found my question here : Utiliser la fonctionnalité d'un device comme valeur dans "Continuer seulement si" et "Changement d'état" - #4 par guim31
Hi @Fabic 
I’ve moved the topic to a new thread.
It’s not possible to retrieve a value from a scene trigger.
What would you use it for? Maybe it can be done another way
Hello @pierre-gilles,
I thought I could implement the « room thermostat » function with Gladys, that is to turn an appliance off or on based on the temperature and the thermostat setpoint.
For that, in my view the simplest solution was to « trigger » a scene in this way:
If variable temperature is less than the value of setpoint then action (with handling of hysteresis by a condition)
After reading the documentation you can do it like @b3n.0 in this post Utiliser la fonctionnalité d'un device comme valeur dans "Continuer seulement si" et "Changement d'état" - #6 par Tlse-vins but with a time-based trigger (which is less clean).
Maybe the easiest for now is to go through Node-RED via MQTT?
@pierre-gilles , I think he wants to compare the room temperature to the setpoint temperature.
But the setpoint is not just a value that you set in your scene but the value of the thermostat object that you developed.
Yes, that’s right
Indeed, it should work by adding a « retrieve the last state » of the setpoint and then injecting it as a value
Yes, but precisely that’s not supported right now!
With @b3n.0’s trick it will work though: Utiliser la fonctionnalité d'un device comme valeur dans "Continuer seulement si" et "Changement d'état" - #7 par b3n.0
Well, in the end I ended up with a Node-RED connected to Gladys via MQTT and it works really well. As a bonus, a modification of the setpoint at night if it’s a Tempo red day:

Completely different topic: in Gladys the device « clic bouton » over MQTT doesn’t work on my instance. Is that normal?
Good evening,
I already use Gladys for my heating and finally looked into the « new » Thermostat developed by @pierre-gilles a few months ago.
To make it useful, I need to be able to choose a value with this thermostat, add one degree for the high setpoint and subtract one degree for the low setpoint (e.g. if I choose 20°C, the heating turns on at 19°C and turns off at 21°C).
So I make a scene in which I retrieve the thermostat value, send the operation via mathjs and then…
Mathjs doesn’t accept my ‹ Thermostat › variable even though it works with numbers and then…
I don’t know how to choose the result in « control a device » towards a dummy MQTT device.
Does what I’m trying to do match the problem mentioned above? Is it not supported? How off-base am I?
Edit: I saw here that @bertrandda had worked on the topic — is it better that I shelve my project and wait?
Are you testing by executing the global scene, and not by clicking the « Try » button on the HTTP request? The Try button does not send variables because it only executes that part of the scene
Indeed, at the moment this is not possible. I don’t know where @bertrandda stands on the subject, and I don’t think it’s in active development, so if you want to take the topic up, you can! 
I had something working; I just needed to write the tests. I’m trying to push the code quickly to see if it works for you.
Yes, and the error message is: ‹ Error: Syntax error in part \u0026quot; + 1\u0026quot; (char 10) ›.
My scene block looks like this :
If I put ‹ 20 › instead of the variable, it works…
As such, it’s not a big deal since the math functions will be integrated, but I’d like to know what I’m doing wrong…

@GBoulvin I tested it at home by creating this scene:
I start the scene and in my messages:
