A coop sensor for chicken keepers
Every hen accounted for, before you close the door.
A small sensor that fits to your coop door. Each hen wears a light leg band, so your phone can show you who's inside, who's still out, and who hasn't come home.

The 9pm headcount
Foxes don't wait for you to finish counting.
Every evening it's the same: open the door, try to count heads in the dark, and hope. The one you can't see is the one that matters.
-
Counting in the dark
Opening the door lets the warmth out and lets a fox in. So most nights you don't count at all — you assume.
-
One missing hen looks like nothing
A hen who never came home looks exactly like a hen tucked in the far corner. You find out days later, when the eggs stop.
-
Trouble shows up late
A hen going broody, getting bullied or feeling off shows up first as a change in habit. Nobody can remember habits.
How it works
Fit it once. Then you just know.
-
STEP 01
Give each hen a band
Snap a light band on her leg. Nothing to charge, nothing to open at the coop. It just lasts.
-
STEP 02
Fit the sensor
One weatherproof frame fits around your pop hole — right alongside your existing manual or automatic door. It notices each hen as she walks through, so it always knows which side she went.
-
STEP 03
Check your phone
Open the app and you'll see who's in, who's out and who hasn't been seen today. Nothing to check unless it tells you.
The kit
What lands at your door.
One box, ready to go. Plug it in, fit it to the door, and your flock shows up on your phone the first time a hen walks through.
- The sensor — one small box that fits to your coop door.
- 12 leg bands — sized for standard hens. Refill packs of ten when the flock grows.
- Power lead — 3 m weatherproof cable and 5 V plug (or run it from a USB battery pack).
- Screws and template — pre-paired in the box, fits in 15 minutes with a screwdriver.
- The app — set up by email, works on your phone and laptop. No subscription to watch your own birds.

Questions
The things keepers actually ask.
Something else? Mail [email protected] and a person answers.
Do I need power and Wi-Fi at the coop?
You need a 2.4 GHz Wi-Fi signal that reaches the coop and a 5 V power source. We include a 3 m lead and mains plug in the box. If your coop doesn't have mains power, the sensor uses very little energy and runs happily off a standard 5 V USB power bank or small solar battery pack.
How does it know if a hen is going in or coming out?
The sensor has two readers — one on the outside of the doorway and one on the inside. As a hen walks through the pop hole, her leg band passes one reader and then the other. Whichever side reads her band last tells Curam whether she just went inside to roost or stepped out into the run. And because it frames the opening, it works right alongside automatic coop doors like Omlet or ChickenGuard.
What if a hen loses her band?
The bands snap firmly shut and stay on through dust baths, mud, and moulting. If one ever goes missing or you add new hens to the flock, you can snap on a spare band from a refill pack and assign it to her name in the app in two taps — her past history stays intact.
What happens if my internet drops?
The sensor keeps working on its own. It saves every entry and exit with the exact time in its onboard memory and updates your phone automatically the moment your Wi-Fi comes back online. For keepers who prefer a completely local setup, Curam also supports local network hosting and Home Assistant over MQTT out of the box.
Can I run more than one coop?
Yes. Our Flock (2 sensors) and Smallholding (4 sensors) kits put all of your houses on one screen. If a hen decides to roost in the wrong house for the night, you'll still see that she's safely inside — and exactly which coop she chose.
How do updates and support work?
Your sensor updates itself automatically over Wi-Fi whenever we release improvements, with zero monthly fees. If anything ever looks wrong, email [email protected] and you'll talk directly to the person who built it.
What if it isn't for me?
Send the kit back within 30 days of delivery for a full refund. Because leg bands that have been worn by a hen can't be reused, we just ask that you test the sensor on your coop door before fitting the bands to your flock.
