First to answer your overall question - the current dev docs are here:
https://smartthings.developer.samsung.com/docs
anything older - ignore…
OK - now I follow - this has nothing to do with HUE - it has to do with a poorly maintained DTH.
OK - so the best link in that thread that comes CLOSE to working is THIS DTH:
Ubuntu Pastebin
But there are some significant problems with that DTH - The BIGGEST one is Smartthings no longer supports the ‘THERMOSTAT’ capability and instead broke it into:
- Temperature Measurement
- Thermostat Cooling Setpoint
- Thermostat Fan Mode
- Thermostat Heating Setpoint
- Thermostat Mode
- Thermostat Operating State
- Thermostat Setpoint
So you need to start by taking that DTH linked above and modifying it to:
add all of the necessary capabilities above and then replacing instances that reference the THERMOSTAT capability with their counterparts in the capabilities you added. (In most cases just adding the capabilities in and remarking out the old thermostat capability should work - I believe the actual attributes, properties, methods, etc. of all of the new capabilities match their counterparts in the old monolithic THERMOSTAT capability.)
Just by making that change if you do it correctly - the system should take over and say - oh wait this is a standard capability - I have a way of showing that. And it SHOULD give you some basic controls. (If you don’t use the app a lot like me, this might be enough to get you going)
NOW - once you get the basics in to make it WORK, how to customize the DTH completely changed after last December. They now use ‘custom presentations’ to modify the default display of a capability. ALL Of that is currently in beta - learn more about that here:
Beyond that you’ll need someone with a lot more DTH authoring experience than I have to troubleshoot if it goes sideways…
