#Smart light switches that support "decoupled mode"

Hi, I've been looking at smart switches that support "decoupled mode" which you use to separate the physical switch from the relay. The reason for this is I like to be able to change the colour of bulbs, however smart bulbs have the obvious flaw that you lose the ability to interact with the physical switch. If you are walking past a light switch, it's sometimes more convenient to turn it off at the switch rather than using an automation, however if you do that with a dumb switch + smart bulb then you cut the power to your smart bulb and can't use the smart controls anymore.

The workaround for this is to use smart bulbs in conjunction with smart switches that support decoupled mode. Use the decoupled mode to separate the physical switch from the relay, and then configure the switch to toggle the smart bulb's on/off state via a HomeAssistant automation.

For this a good option is Aqara H1. The only sad thing is that these switches don't support dimming via the physical switch.

My question is, I wonder if it's possible to "simulate" dimming with decoupled mode. For example, configure a long press or double press on the switch to adjust the brightness of the smart bulb. If it is possible, how would it function - i.e. would you have to configure it to set the brightness to a specific level, therefore need a bunch of different automations for different levels of brightness that you may want to use... or would it be possible to have a long press cycle up and down brightness levels until you let go, like a real dimmer.

Any input would be highly appreciated!

I use the sonoff tx switches. They can be flashed with esphome and do exactly what you are after with different actions on double press or whatever. Obviously, the smart bulb would have to support dimming.

Where I have dumb bulbs, the relay is toggled when the switch is pushed. Where I have smart bulbs, the relay remains closed and HA toggles the bulb.

Bonus tip, I have the switches with 3 relays and 3 buttons everywhere, even if it's only got a single circuit. The extra buttons are useful for all sorts of things like turning on table lamps or the TV as lightswitches are often in convenient places

With a dumb bulb - I doubt it. The relay wont open / close fast enough to do proper PWM.

If you have a smart bulb, then it should work, although I've not done it. You'd need to have an on_press action in esphome and write some code to adjust the brightness of the bulb.

Here's a possible solution - although I've not tried it

Yeah was meaning with smart bulb. Thank you will look into it

I'm surprised no one has brought up the inovelli line of smart switches

There is a demo on that page where the designer shows how to use it to cycle through colors and have the color match the bulbs in the room (or well, have the bulbs match the color displayed by the switch)
