MARKETPLACE
Every device here carries the Blue Raven badge: open firmware, captive-portal config, and data that goes where you point it. Tell us which ones you want and we'll build them in that order.
Your garden, reporting to your database.
The reference Blue Raven device. An ESP32 with a capacitive probe that wakes, reads, and posts moisture straight to whatever endpoint you configure in the captive portal. Open firmware you can flash today.
EMITS: moisture %, raw ADC
Time-window captures straight to your storage.
Set a capture window in the portal and stills land in your own bucket. No cloud subscription, no app, no footage on anyone else’s server. Your security feed belongs in your stack.
EMITS: JPEG frames, capture metadata
The device that started all of this.
Step on it and your weight posts to your health app before you finish brushing your teeth. No account, no ecosystem, no losing your history when a subscription lapses. The founding use case for Blue Raven.
EMITS: weight kg/lb, body timestamp
Ask your air how it’s doing. Locally.
CO2, PM2.5, and VOC on a local REST API your dashboard polls whenever it wants. Serve mode means zero outbound connections: a device that never initiates a connection cannot phone home.
EMITS: CO2 ppm, PM2.5, VOC index, temp/RH
Grams to your nutrition tracker as you cook.
Weigh an ingredient and it lands in your nutrition log automatically. Pairs with whatever health stack you’ve built, not with a branded recipe app you never asked for.
EMITS: weight g/oz, tare events
Room occupancy without cameras.
mmWave radar detects presence through furniture and darkness. Your automations query it locally: lights, climate, do-not-disturb logic, all without a single image ever existing.
EMITS: occupancy bool, motion level
Know what every appliance actually costs.
Per-appliance power draw, pushed to your stack on an interval or queried live. Find the vampire loads, graph the fridge, automate the space heater. Your meter, your data.
EMITS: watts, kWh, voltage, relay state
Fridge, freezer, greenhouse, sauna.
A sealed probe with thresholds you set in the captive portal. Get a webhook the moment the freezer door is left open or the greenhouse dips toward frost. No app between you and the alert.
EMITS: temp °C/°F, RH %, threshold alerts
Under the sink, before the damage.
Months on a battery, silent until it matters, then a POST to any webhook you own. Pair it with your own notification logic: text, siren, smart valve. You decide what a leak triggers.
EMITS: leak bool, battery %
Open or closed, answered locally.
Your security dashboard queries state directly on your network. No cloud round trip to learn whether your own front door is open. Build the alarm logic you actually want.
EMITS: open/closed, last-change time
DEVICE IDEAS
Suggest a device below and it lands in our review queue. The ones we adopt show up here as official ideas, and anyone can second them. The most-seconded ideas shape the build order.
Water temp, pH, and water level pushed to your own dashboard. Alert webhooks you define, for the fish you actually care about.
CO2, temp, and humidity for indoor growers, with a relay for the exhaust fan. Serve mode so your automation polls it locally.
A battery sensor that POSTs the moment your physical mail arrives. The classic first homelab win, minus the cloud subscription.
