I use LightwaveRF for my lighting in my house. Works very well, but I fear it may all have to be replaced at some stage due to incompatibility with everything else - this is the problem with early adoption. I have a Ring doorbell. Few HikVision POE security cameras for good measure. Some VOIP phones too.
Needless to say they don't talk to each other. Future plans include heating controls and wireless doorlocks. No reason.
I'd like to go 'All-in' with one system but that just isn't feasible yet. These closed source systems mean if the company goes titsup, I'm fucked.
We need another 10 years for the industry to consolidate or at least sort its shit out imho.
