I have recently purchased a few “Skydance” light controllers. The range is huge and includes a full spread of 120/220V devices aswell as 12/24V and DMX controllers for dimming/leds/RGB etc.
These are my specific devices…
They all interoperate via a proprietary 2.4G (not 433!) RF protocol. This is (unfortunately) undocumented and clearly operates only between “controllers” (remotes/wall switches etc) and “remote devices” (light units). There is no update on states from remotes to controllers.The actual quality of the devices - especially the dimmer wall switch and remotes feels good.
However there is a WiFi connected “relay” (and some wifi connected controllers). The app is truly woeful but investigation showed it is direct local (unencrypted) control between the App and the Controller with no remote cloud. Having spent some time with packet captures and in combination with boydg I have managed to replicate the basics of control for my devices. Initially via a Python script I have actually implemented on HA via Node Red…
Essentially within HA I create template lights that “do nothing” directly - but NR picks up state changes and triggers the necessary control via the WiFI relay. There is of course no feedback - so the switches do not stay in sync if lights are controlled locally. not ideal, but acceptable in this case for me.
This is proving to work well in practice. With on/off/dim and preset scenes etc all working
Anyone looking at these devices (which also have other names on the normal chinese sites) I’m more than happy to share more details. - just PM/mail me. I would imagine a component/integration is more than possible with the understanding we have now…but well beyond my coding/python at this point.
