Led strip lighting

[Amaretat]

I am looking into doing some led strip cabinet lighting.
what i am looking to do is have the Led strip turn on when i open the cabinet doors and still retain the ability to turn them on with the remote control.

The way i was thinking of doing it was to buy some Led strips with an IR controller and do a parallel wired Push to OFF switch circuit to turn on the Led's when i open the cabinet doors

I know i won't have control over the color and power when turned on via the push to off switch.
but would the Led strip be ok with the power received when i bypass the led controller or does it also work as a voltage controller? or do i need to measure and possibly wire in a resistor?
any thing obvious i am missing?
would this be the way to go ?
with regards Ama

What kind of LED strip are you going to use? There are different types and what you can or cannot do depends on the type of strip.

i was looking at something like this https://www.amazon.de/-/en/Bluetoot...p&qid=1675427813&sprefix=led+s,aps,100&sr=8-6
or if you have a recommendation for a type of strip i should be looking for that can do what i am looking for

This kind of LED strip is typically powered by 12 V but there's no clear indication on the website for this strip.
Usually (again: no info on the website) the three LED colors use a common + 12 V rail and 3 separate gnd rails for Red, Green and Blue. These rails are driven by MOSFETs within the controller that pull the rails to gnd to light the LEDs of the respective color. Brightness is controlled via pulse width modulation (pwm).
If that is so with this strip, you can turn on the LEDs color by color with a switch that grounds the rail for the colors. This will not damage the controller, but you won't be able to control either color or brightness when the switches are on.
It will also be a bit fickly to insert the switches into the connection from controller to the LED strip.

You might not need to DIY it all yourself. There are LED light bars out there that could meet your needs — battery-powered, with motion sensors, and remote control options. These could automatically turn on when you open the cabinet doors without the need for complicated wiring. Worth checking out before you get into custom wiring.
If the admin allows, I can post a product I’ve purchased for your reference: Motion Sensor LED light bars

A "push-to-OFF" switch can be used to bypass the IR controller and connect the LED strip directly to the power supply. When the cabinet door opens, the switch will close, powering the strip. If you want to make a versatile LED controller, you can see here:
