2025 pet IoT — the DIY era, properly arrived

“The same year, the same small company inverted two of my calls. Tractive shipped the resting-vitals collar a decade of giants never managed — then bought Whistle from the giant that gave up. The empire didn't expand; it sold its device leg to the underdog that had just out-engineered it.”

Tractive Base Station teardown — 2025 silicon, 2013 arch

“Tractive's Base Station ships an nRF52840 — a Swiss-army-knife radio that supports BLE 5, LE Coded PHY for 4× range, Thread for mesh, Matter, and 802.15.4. They use it as a plain BLE advertising beacon. The hardware is 2025; the architecture is 2013. The vendor doesn't know how to use what they bought.”

Twelve years of pet IoT — the long-arc retrospective

“Twelve years in. Mars just divested Whistle to Tractive — the empire that bought the device leg in 2016 sold it back nine years later. Cloud-dependency lesson written. DIY response just starting. The pet-IoT category is the smart-home category five years behind — same arc, smaller scale, higher stakes.”

Mars divests Whistle to Tractive — collar market state

“Empires don't sell off devices when the strategic value is rising. Mars's vertical-integration thesis just contracted — the empire that bought Whistle in 2016, AniCura in 2018, VCA in 2017 just let go of one of its data-feed legs. The empire is starting to look smaller from the inside than from the outside.”

DIY ESP32 pet feeder — vendor-cloud independence for $35

“An ESP32 + servo + 3D-printed hopper is $35 in parts and zero monthly subscription. The reliability is whatever I make it. The vendor solvency dependency is gone. This is what the post-Petnet pet-IoT category should have shipped years ago.”

2024 pet IoT — Atom passed, Find My trackers landed

“Looking back: a hard year. The pet-IoT data did its job — caught Atom's decline if I'd been looking at the right metrics. The lesson, expensive: dashboards must adapt to the pet's life stage. I missed the signal because I wasn't watching the right view.”

Atom's last year — what the data told us, and what I missed

“I read the data for six months. The signal was there. I was watching the wrong metric. The metric a healthy dog tracks is not the same metric a sick dog tracks. Different dashboards for different stages.”

Find My pet trackers — Apple's network opens to third-party

“Find My-network pet trackers don't replace cellular trackers like Fi. They complement them. BLE + 1 billion iPhones crowdsourced relay works for finding a lost pet in a city. It doesn't work in rural areas, and it never tracks in real-time. For active outdoor tracking, cellular still wins.”

2023 in pet IoT — a new house, and the year the data started to matter

“For ten years this was a hobby — gadgets on healthy animals, data I collected because I could. This was the year it stopped being decorative: Atom's collar flagged a real change before I'd admit I was seeing it, and the vet found a heart murmur. The category is finally being tested for what it's actually for.”

Behavioral AI on pet cameras — what works, what's marketing

“The behavioral AI that works in 2023 lives in veterinary clinics with $40,000 high-frame-rate cameras and trained-classifier pipelines for lameness detection. The behavioral AI on a $250 consumer camera doing 'is your dog happy' is marketing. The category distinction matters.”

Mars Petcare — the food company that owns your dog's collar

“Pet wellness 'recommendations' that come from a company that also sells the prescribed food, runs the prescribing vet, and owns the analytics that 'detected' the need are not health advice. They're marketing channels. The conflict isn't subtle anymore.”

2022 in pet IoT — Quark arrived, Halo went back, the cat side finally got smart

“The household hit four animals this year, and for the first time the cat side got the analytics layer the dog side has had since 2013. Nine years to instrument the cats. The dog side was the easy half all along.”

Petivity smart-litter — multi-cat analytics, built by Purina

“Petivity tells Joule from Boson with no microchip and no collar — just a scale and a model. That's the genuinely hard problem this category has dodged for years. The catch is who built it, and what the app wants to sell me on the way out.”

Halo Collar — I tried it, returned it within the trial window

“Halo's GPS-fence engineering is impressive — sub-meter accuracy, low-latency boundary detection, multi-mode correction options. The application — delivering uncomfortable stimuli to a dog who doesn't understand the boundary as an abstraction — is where the engineering excellence stops mattering.”

Quark arrives — a second dog, and the pet-IoT baseline starts over

“Same engineer, second puppy, nine years apart — and the collar I reach for without thinking is the one that didn't exist last time and isn't owned by a pet-food company. That's the whole arc of this notebook in one purchase.”

2021 in pet IoT — AirTag landed, Whistle started reading behavior, Halo I won't buy

“AirTag was the most-hyped pet tracker of the year and I don't have one on a dog — because the same anti-stalking chirp that makes it safe for people makes it useless for a pet that can't tell you it's beeping.”

Whistle Health & GPS+ — the 'health' collar with no vital sign

“A collar that infers how your dog feels from how your dog moves is a clever accelerometer, not a medical device. Whistle calls scratching and licking 'health monitoring.' It's behavior monitoring with a wellness score on top — and the heart rate everyone actually wants still isn't on any consumer collar you can buy.”

AirTag on Atom's collar — anti-stalking vs pet tracking

“AirTag's anti-stalking features are designed to alert an unsuspecting person that an AirTag is following them. When the AirTag is on your dog who's exited the geofence, your dog gets the 'someone is tracking you' chirp. Apple's design assumes the tagged entity is a person, and pet tracking breaks that assumption in interesting ways.”

2020 pet IoT — Petnet died, Boson arrived, multi-cat real

“Four of eight on last year's forecasts, and the misses all rhyme: every 'health' collar still infers from behavior, no litter box knows which cat, and I keep building the smart part myself. The category surges; the intelligence lags.”

Litter-Robot multi-cat detection — Joule vs Boson

“Multi-cat attribution by weight works when the cats are weight-different. Litter-Robot's data plus a 30-line Python script give per-cat analytics today, despite the official app not supporting it.”

Boson arrives — the multi-cat engineering problem

“Multi-cat households break the single-cat assumption in every pet-IoT device. The 'which cat is using this?' question becomes the central engineering problem. Some devices have already solved it. Most haven't.”

Petnet collapses — the pet-IoT cautionary tale, written

“A week-long outage isn't a bug — it's what a company looks like when there's nobody left to fix it. The thing that promised to feed your cat couldn't, for a week, and couldn't tell you why. The 'smart' became the failure mode.”

2019 pet IoT — Fi shipped, Whistle went health, Petnet hung on

“Seven years in, the lesson I keep relearning is that the device almost never fails — the company behind it does. Fi's battery was the engineering win of the year. Petnet still being alive was the surprise.”

Fi ships first units — Atom finally has a non-Mars tracker

“Two weeks on Fi. Battery life: 14 days actual, on a healthy active dog. That's 4-5× what Whistle 3 delivered. The LTE-M bet has paid off.”

Petnet's cracks are visible — the early warning

“When a connected pet device's cloud goes down repeatedly without explanation, the company is in trouble. The outage history is the leading indicator of the company's solvency. By the time the bankruptcy notice comes, the pets have already been hungry for days.”

2018 pet IoT — the quiet year before Fi

“The interesting thing about 2018 wasn't a product. It was the absence of one — Atom went four months bare-collar because nothing on the market was worth buying, and I'd rather wait for Fi than pay Mars again.”

Litter-Robot III Connect — the first pet IoT device with real medical telemetry

“This is the rare connected pet device where the data layer adds something the dumb device can't: visit frequency, duration, and weight are the exact signals a vet reads for UTIs, diabetes, and silent weight loss. The litter box sees them every single day. The yearly checkup sees them once.”

The pet-collar power budget — what a multi-week cellular tracker would actually take

“Cellular pet-tracker battery life isn't a marketing number, it's a power-budget engineering problem. The whole game is the modem's average current — and LTE-M's Power Saving Mode is the first thing I've seen that could move it by 10×.”

2017 pet IoT in review — the cat side finally gets data, the feeder gets scary

“Five years in and the misses are always the same shape: vendor ship dates. The structural calls keep landing; the calendar calls keep slipping. I predict on a calendar; vendors don't ship on one.”

SureFlap Hub — finally, a connected cat door for Joule

“The real win isn't knowing Joule went outside — I knew that. It's that three-to-four trips a day is now a baseline, and the day it drops to one is a health flag I'd never have caught by eye. That's what telemetry does that direct observation can't.”

Furbo Dog Camera — first impressions, and the treat-toss is the real engineering

“The treat-toss is the engineering achievement, and it's mechanical, not software. A spring paddle, a calibrated launch arc, a click the dog learns in an hour. Atom now stares at the thing like it's a slot machine that pays out in biscuits.”

Petnet SmartFeeder — a long-term review, and why a cloud-dependent feeder scares me

“A feeder that needs a cloud to dispense food is a bet on the vendor's solvency. When the server is down at midnight, the cat goes hungry — and the device is only as reliable as a company you've never met keeping its servers up.”

2016 pet IoT in review — Whistle goes cellular, Mars buys in, Furbo lands

“The big call I got right was Whistle going cellular and getting acquired in the same breath. The miss, again, was timing — I keep forecasting on calendars, and vendors ship when vendors ship.”

Six months on the Whistle GPS Pet Tracker — the cellular realities

“Claimed 7-day battery. Real 3-4 days the moment GPS is doing the job you bought it for. The 'when it matters' number — dog out, located every few minutes — is closer to a single day. Divide the box claim by two for steady state, by seven for the emergency.”

Whistle's GPS Pet Tracker ships with cellular — and Mars Petcare buys Whistle the same month

“A pet-food company now owns the collar that tells me whether my dog is active enough. That isn't a theoretical conflict — it's the same firm saying 'feed more' and selling the food.”

2015 in pet IoT — the cat side finally shipped, the dog side split in two

“The cat side of the house went from one passive chip to a door that reads it six hundred times a month. That's the whole story of 2015: the most analog member of the household finally got a radio pointed at her.”

FitBark — the pet activity-tracker market in 2015

“Two accelerometers on one dog for a week. They agree on the shape of every day and disagree on the size of it by a fifth — because they draw the line between 'resting' and 'active' in different places. The shape is the dog. The size is a setting.”

SureFlap microchip cat door — Joule's first pet IoT

“I keep calling it Joule's first IoT device. It isn't, really. There's no network in it anywhere — no Wi-Fi, no app, no cloud, no second device to talk to. It's a battery, a coil, and a latch that knows one number. That's the honest description, and it's the most interesting thing about it.”

2014 in pet IoT — the dog side grew up, the cat side never started

“First full year of pet IoT in the house: the dog has a tracker, a market, and a year of data I'd actually act on. The cat has a chip the size of a grain of rice and nothing else. That gap is the whole story of the year.”

Joule arrives — what a pet microchip actually is

“A microchip doesn't find a lost pet. It identifies a found one. No battery, no GPS, no range past a few centimeters — the chip just answers one question, and only when something else asks it.”

Tagg vs Whistle — cellular vs BLE pet-tracker philosophies

“Cellular tracker, $7.95 a month. BLE tracker, nothing a month. But the subscription isn't the real difference — the radio is. One keeps a cellular modem half-awake and dies in three days; the other sleeps until your dog walks past the house and lasts a week.”

Atom arrives — Whistle launches a dog fitness tracker

“Whistle is Fitbit for dogs. That's the easy comparison. The harder question is whether tracking activity actually tells you anything about a dog's health or whether it's just a number we like to look at.”
