I’m looking for a smart dimmable CCT LED-strip Controller that would be controllable with a smart dimmer like the Shelly Dimmer2. My reasoning is that this LED strip is the main light in that room and I want to make sure that I’m able to turn on the light regardless of any network connection.
Considering you are ok with Shelly products, instead of using LED-strip controller + Shelly dimmer, go for Shelly RGBW2 + suitable power supply.
Shelly RGBW2 can be toggled with AC. It depends on available wiring though.
Another choice is to use a dedicated system providing pair of remote and controller. Like MiLIght system. Considering this pair establishes custom communication between each other, it’s not dependent on a network connection (in a common meaning). The remote of MiLight is to be mounted instead of physical switch, powered from line behind it, but not breaking the circuit: AC has to be delivered up to light fixture. Controlled mounted inside the fixture is controlled by the remote
The issue with the Shelly RGBW is that it doesn’t really support CCT LED strips, there’s probably a way to hack it to work, but i just imagined it would be easier to just use a controller with built in CCT support. I would really like to avoid Remote+Controller, the systems are often short loved have have pretty limited “smart” functionality in my experience.
I understand your concerns. I can only share an info and experience I have.
Yes, Shelly RGBW2 cannot be configured natively to cct, regardless lot of promises. But it is possible to easily create CCT light in HA ising mqtt, combining two channels of rgbw2 into single light.
It must be done using mqtt. It’s not possible with official shelly integration.
Yeah, I might end up choosing, wiring it up as a two channel LED strip, and using a Shelly Dimmer2 in place of the on/off/dimming switch, local control for light level and phone / smart home control for Light Temperature control, which is optimal if it works well.
Not sure about the mention of the Dimmer2. RGBW2 must be supplied with an external power supply (12 or 24 usually depending on LED strip type). You cannot dimm its power supply with a dimmer. If you mean to control RGBW2 remotely with other shelly devices, then there are better choices (like Shelly i3). But I understood it’s not what you are looking for since you want to make it as much independent from the wireless network as possible.
I use RGBW2 powering LED lamp, controlled with a physical wall switch (thanks to that black box on your schematics) for several years now and it’s reliable. But since the rgbw2 is mounted in the lamp fixture, it requires an additional wire from the switch to rgbw2. Fortunately, I had enough wires between the switch box and the fixture.
Other note: I combine 2 channels into CCT light using rgbw2 set to color mode (not in separate channel mode which seems to be more intuitive). This is because of yaml code I had found suitable for such a conversion.
Right now I’m thinking about reasons why it cannot be combined from white-channels. AFAIK this mode requires controlling on/off state of each rgbw2 channel separately (2 different mqtt topics) while AFAIK HA’s mqtt integration doesn’t provide an option to modify 2 mqtt topics as a result of on/off action.
But it’s the detail actually. Using color mode is sufficient for this use-case.
Yes, there is on/off switch on the schematics, but its intention is to control the rgbw2, not to break its power supply line. The rgbw2 has to remain powered the whole time.
