I have created a new iOS app that gives me basic control of my Domoticz and Philips Hue installation, like flipping switches, setting values, reading out sensors and other information and viewing cameras.
It's not designed to be the one-and-all controller of all features of each system . You can rather think of it as a universal remote control where you can even arrange the layout of the buttons to your liking.
It's still a bit rough around the edges, but it works well for me and I'd like to invite you to my first public beta test.
Lights & Switches is available in Test Flight:
There is also a Discord available for discussions
I'd be happy if you would give the app a try and let me know what you think.
