I need another chime for my doorbell, because the one I have isn't audible everywhere I need it to be audible.
I see threads on the Aeotec and Axxess solutions, and I also found (but saw no thread on) Smartenit's solution, and plenty of talk on video doorbells... but I don't think I want to spend that kind of money for a doorbell.
There's also discussion on wired doorbell sensors, but my current doorbell isn't wired and I have no wires (though I think I have a transformer, so maybe the wires are embedded in the walls somewhere).
I wonder if wireless doorbells like the one I have typically use a standard protocol for which I could get a receiver to plug in somewhere? I see mention of 433MHz a lot, but that's just an unregulated frequency and may not be associated with a common protocol. Or maybe I could crack open my current doorbell receiver and try to install a wired sensor inside of it to relay its detection to Hubitat. Has anyone tried that? In which case I probably don't need a dedicated "doorbell sensor" but any switch or voltage sensor that'll fit inside something else's box.
Or if I do have to spend money, I'd at least like what I end up with to be more flexible and more fun than just a doorbell.
One thing I definitely want to retain is a dedicated link between the doorbell and at least one chime, so that I don't have to rely on other things being up and functional, but I would also like to relay the signal via HE for additional chimes and automation.
