It is getting even tougher because a dashboard is exactly the sort of thing that is being targeted by SmartThings’ upcoming API monetisation. If you install your own you may end up paying $5 a month for API access and it may actually be cheaper to use commercial services. Fine details are a little thin on the ground at the moment.
So, my wife doesn’t really like these options.
Is there something else aesthetically pleasing?
Would something like Brilliant or the aqara panel hub S1 Pulse be able to control SmartThings?
