How difficult can it be?
I've had a day of running around trying to buy smoke alarms, and CO2 alarms, which I have to install as a landlord.
I started my quest ot B&Q, which I think is our equivalent of Home Depot. Theirs were rather pricey.
While I was there, though, I bought a Doorbell for £25.
Nice and easy, all you do is plug the ringing bit into a wall socket, and attach the button bit to outside your door. The button does not need batteries, but uses
kinetic energy to transmit RF to the main bit.
I haven't had a doorbell for nearly 40 years, because the last one I bought just didn't work. It had an electro-mechanical dual chime, with a solenoid, and a mains
transformer mounted on the wall in another box, and a cable running to the push-button outside. The trouble was, I would get home from work several times to find
the chime unit just buzzing, and consuming electric, because the solenoid would not dis-engage after operation. I just disconnected it, and it is still there attached to the wall,
disconnected nearly 40 years later.
Anyhow, fast forward to today's swanky new bell. First time I pressed the button, it sounded.
A few more attempts, and I found it didn't always work on the first press,...or the second.
Sometimes it might sound on the third or fifth attempt.
On my final attempt it only sounded on the tenth attempt.
Enough! I packaged it back up and took it back to B&Q for a refund.
This is not exactly Windows11, but how difficult can a doorbell be?
I am tempted to make one with a bit of string, a beater, and a cymbal.
