His exercise routine is somewhat variable but he usually goes for a short jog a few dozen times a day. Most often at 5 am, for whatever reason.

Cats are crepuscular animals. They are "programed" do start at 5 AM, hunt, and go back to sleep until afternoon. Living in homes tweaked them a little, but the 5 AM thing is still strong in a lot of them (mine included).

So not specifically at 5AM, but around twilight. In my area, and for my cats, that changes a lot between summer and winter.
Same for my chickens, which is why "automatic chicken doors" are difficult/impossible around here: It'd need to calculate sunset and sundown, and then also consider clouds and trees: in winter the sun sets around 16:30, but the low angle makes sunlight more blocked by clouds, particles and trees and such. My chickens often decide its bedtime before 16:00 already.

The automation features in Apple Home can be set to do things at sunrise or sunset. These track down to the minute the sunrise/sunset times from the weather app data for your location.
Your best bet, if you really want an automatic chicken door, is to get a dumb one that just opens when powered on and closes (via springs) when powered off, then plug it into a smart outlet automated to turn on at sunrise and off at sunset.

When I did it, I closed the door at nautical twilight. The key is that you need to close the door after the chickens roost but before the nocturnal predators come out.
kQq9oHeAz6wLLS 3 hours ago [-]
Automated chicken door isn't too difficult; remember the goal is to allow them to come in or out, not to make them do so or wake them up, though they do get conditioned to the door opening.
I made mine to open at actual sunrise (except in the summer; I keep them in until 7am because the coop is cooler, and if let out they can get loud before my neighbors wake up) and close it at actual sunset (not civil twilight, which most people think of when you say "sunset"). Generally the door is open well after the birds are in bed, which is fine.
Aside from some dumb birds when they were younger, I've never had one locked out (and those dumb ones were trying to nest in silly places, and weren't going you come in no matter when I closed the door).

As a former rabbit owner I can attest that around 5 am was when the theater would open, and the first thing on was always this improvised bit called “abused animal trapped forever in a cage”. Lots of special effects too, there was gnawing and rattling and stomping. When I did open the cage door, she would jump out, take a look around and happily go back to napping right there in front of the cage.

To complement the treat rewards, can you get the cat wheel to power a small pump to provide a water fountain for the cat?
Assuming the treats are dispensed after a variable amount of distance is travelled on the cat wheel (to turn your cat into a 'gambler' of sorts, thereby keeping your cat on the wheel in the hope of a treat), a water fountain with 'fresh' water should enable your cat to avoid dehydration (due to the excessive exercise, chasing treats).
Harvested energy could also power a fan for the wheel and/or a heat pad in your cat's bed.
With these improvements, those short jogs will inevitably become marathon runs.

I love that two people independently arrived at "my pet uses a wheel, therefore I need telemetry"
Project:
> The main parts are an ESP32 attached to a hall sensor, which I positioned close to the wheel. Using a magnet attached to the back of the wheel, this tells the ESP32 when a full rotation has completed. It gives a timestamp (and total distance) to each magnet-pass, which is stored on the network. A python script (on my laptop) then retrieves this data in the morning, turns it into a .FIT file, and uploads it to Strava through the Strava API (with a randomly chosen run title, taken from a mostly AI-generated list of options, as I needed >100). In terms of manual additions, I had to add the photo manually, and Mollie had to do the running.
Reminds me of Nobel and Ignobel prize winner Andrei Geim, who authorer a paper with his hamster, H.A.M.S. ter Tisha. As I remember, he added Mr/Ms Tisha to be able to write “we” instead of “I”.
Also built a bike computer for my daughter using an esp32, reed switch and magnet.

Not by much. A mile is 1000 paces, or 2000 steps [0]. 10000 steps is 5 miles, 10km is 6.2 miles.
Walking on flat, paved surfaces, I do about 1850 steps per mile of distance[1]. I have a pretty long inseam, so I'm not surprised that I'd be under 1000 paces. Given that roads weren't paved with concrete or asphalt until relatively recently, I'm not surprised that the Roman mile is a little shorter than our current one[2].
So one step is a little over half a meter. That doesn't sound like a hampster's stride.
