Get a Ring doorbell device (or maybe a Nest or another brand device). (although I just read that you don’t own a smartphone - maybe you have a relative who can set up such a device for you. I can control my Ring devices mostly through a computer app but Ring has threatened in the past to inactivate the Windows app and make users rely on an Android or iOS device - if you have an iPad or an Android tablet, you could probably control a Ring device through that).
I opted to get an original Ring Doorbell Pro wired device back in 2016 or 2017. It’s still working great.
I opted for wired vs. battery-powered as I didn’t want to have to worry about a rechargeable battery eventually dying. Read the instructions before you get one (of any brand). You might have to upgrade your doorbell transformer. IIRC, you have to have at least a 16-volt transformer for the Ring device that I got. I bought 16-volt transformer at Home Depot to replace the 12-volt transformer we previously had. You can either install such a doorbell and transfomer yourself or hire someone to install it.
Your install location has to have good Wi-Fi connectivity. You can use your smartphone as a meter to judge whether signal strength is good enough. Since our router signal had to go through an interior sheet rock wall or two as well as the exterior brick wall, we installed a NetGear Wi-Fi extender in an interior electrical outlet close to the front doorbell position.
The only glitchy thing over the years is that if there’s a power outage, the original Ring Doorbell Pro often fails to reboot when the power comes back on. Flipping the circuit breaker it’s on off for 10 to 15 seconds, then flipping it on again always gets the device up and running again.
Just as a doorbell, it works great. You can get Wi-Fi doorbell chimes to plug into electrical outlets in far corners of your house so you don’t have depend on one physical wired chime (that may not be very loud). Also, via the Ring app, you can sound an alert on your smartphone or if you have notifications sent to your HA’s, you can hear the doorbell ring in your ears and you can choose the sound of the doorbell chime/alert from a bunch of options and control its loudness.
The video/speaker aspect of such a device is great, too. We were once speeding up to Austin at 70 mph on Interstate 35. Via a cellular connection, with my smartphone mounted on a ProClip phone mount on the car dashboard, we heard and saw an Amazon driver ring our front doorbell with a package for my wife. The wife turned on the intercom feature, talked to the woman, and asked her to leave it with our next-door neighbor. Then, since the doorbell video pointed in the direction of the neighbor’s house, she could actually see the neighbor come out into her front yard and take the package from the Amazon driver.
Probably all such smart doorbells these days have AI that allows you to select the area in front of your door that you want to monitor and allows you to set the sensitivity and other parameters of motion detection at your front door. And if you have a bunch of such devices, you can switch them all from a “I’m Home” setting to “I’m Away-Please Guard the House” setting with one button tap.
Relative to your not having a smartphone, that’s perhaps unfortunate. We control our interior and exterior lights, our upstairs and downstairs thermostats, our dehumidifiers, our Ring devices, electrical outlet plug switches, Amazon and Google AI assistants, as well as my TV streamer for my HA’s, all through our smartphones. When we drive into our driveway at night we can turn on the lights in our driveway from our car and open the garage door all from a smartphone. And many of the apps have distinctive sound alerts. When the wife come home (or anyone else should somehow manage to open the garage door,) a distinctive chime sounds in my ears and if either of us forgets and leaves the door up, I get a similar distinctive sound notification at a time interval that I can set that the door is still up. So my HA’s have become a sound monitor of what’s going on in my environment. Such alerts are only occasional, not constant, and I value the transmission of info as to what’s going on around the house and am not bothered by sound notifications.
Even if this spiel doesn’t help you, it might be of some interest to someone else with hearing loss who has trouble hearing a physical doorbell chime as soon as they get any distance from it.
