People most typically run into this with smart bulbs, so there are a couple of FAQs in the forum that should give you some ideas. The same principles apply whether it’s a Wi-Fi camera, a pump, a smart bulb, or any other device where you don’t want the power turned off at the switch.
The main solutions all come down to a couple of basic categories:
put a child safety lock over the existing switch to remind people not to use it. This tends to be most successful if you have voice control of the devices, because most people seem to like to use voice control and they just need the reminder.
For a device which should be turned off only in emergencies, probably like a camera, there are also switch locks available which are intended for use with things like freezers or medical equipment. Very similar to the child safety locks, it’s just that they lock completely.
swap out the existing switch for a battery operated device. There are some which are designed to fit over the top of the existing switch, and some which would need A little more creativity.
swap out the existing switch for a mains powered Switch which does not control the current
This is what I use. I just moved not too long ago and I have set up a couple of lights in the house with smart bulbs. I had to run neutrals to many switches in my house as it did not have them. But on some switches the smart bulbs worked well and were cheaper and easier than running new wire.
Even though I know not to turn off certain switches, I find myself reaching for them from time to time as I leave the room . These covers remind me not to.
My wife turns off the switch that controls the Hue lights in the upstairs bathroom. Does this virtually every night.
Then she asks why the nice motion-based night light arrangement I did with them does not work. lol
I put some clear cellotape over the switch button, and its 95% invisible to the eye. I like this solution because sometimes i need to reset some of my bulbs, so i need to be able to turn the switches off and on. Forget my wife, a few times I have tried to turn switches off, just did it about 30 mins back lol
Paintings. I have been using things like paintings, hanging planTs and even Floating shelves with ornaments that mark it. House looks much nicer and the lights are available when I need. It alp makes a person who is residing at the house remember not to switch them off
