Need help with Capabilites

Developer Programs Writing Device Types

Hello there. I want to connect a Thermostat. Now, I use the capability “Thermostat”. For more informations about the capability: http://docs.smartthings.com/en/latest/capabilities-reference.html#thermostat. Now I want to change the value of an attribute. In the example below I want to change the attribute coolingSetpoint. But the Problem is that I always get null back on the attribute. Can someone help me or tell me where my mistake is?

Thanks

heatingSetpoint is an Attribute, not a variable.

To access an Attribute in a DTH you need to use a the currentState method like:

device.currentState("heatingSetpoint")

Thanks you very much. And how can I change a Attribute?

device.currentState(“heatingSetpoint”) = variable doesnt work…

4

sendEvent(...) … See the Docs for details.

(NB: In a DTH, if you have a parse() method, its return value is automatically passed to sendEvent()).

5

The prob is that I have a cloud device and they dont need the parse method. Im gonna look after this send Event method…

Thank you

It worked! But now I got another Problem. When I change the Attribute, it doesnt get changed in the tile. How can I do that?

It’s best you look at some great examples first…

Tiles are documented, but examples are even better.

“2 Weeks”??? I’ve been here for over 5 years.

SmartThings is an incredibly powerful and complex platform. You can’t expect to become proficient in something in 2 weeks!

Patience and persistence is required to learn anything… especially SmartThings. There’s no “SmartThings for Dummies” book or online lessons; so you have to spend a lot of time exploring and reading and experimenting with the simplest possible code … ideally for months.

There’s a ton of code here and other places: GitHub - SmartThingsCommunity/SmartThingsPublic: SmartThings open-source DeviceType Handlers and SmartApps code
