An RBMD app · iOS & Apple Watch
Grill smarter, the open way.
Grilly is a native companion for GrillEye thermometers running the open-source free-grilly firmware. It talks straight to your grill over local Wi-Fi, with multi-probe monitoring, zones, smart cook alerts and live charts. No cloud, no account, no tracking.
What it does
Everything you need to nail the cook.
Built for low-and-slow and high-heat alike, Grilly turns your GrillEye into a calm, glanceable command centre.
▣
Zones & ambient probes
Group probes into grill zones, direct vs. indirect heat, and let Grilly estimate time-to-target per zone.
⏱
Smart cook alerts
Get notified at target, near-target and for range modes like hot smoke, cold smoke and holding, de-duped so they never spam you.
📈
Live charts & history
Temperatures are recorded on-device so you can review the whole cook, with optional InfluxDB back-fill for the data nerds.
🍗
Food presets & modes
Sensible probe modes and food presets get you to the right target fast, then dial it in by hand whenever you like.
🔒
No cloud, no account
Grilly connects directly to your grill on your own Wi-Fi. No sign-up, no telemetry, no data leaving your network.
On your wrist
Your grill, a glance away.
The native Apple Watch app keeps your probe temperatures right on your wrist, so you can leave the phone inside and still know the moment the brisket is ready. Tap, glance, back to the party.
Alerts fire on the watch and the phone together, so a milestone never slips by while you’re tending the fire.

- Connects directly to your grill over local Wi-Fi.
- Temperature history is stored on-device by default.
- Optional InfluxDB integration sends data only to a server you own.
Good to know
Frequently asked.
What do I need to get started?
A GrillEye thermometer flashed with the free-grilly firmware, your phone and grill on the same Wi-Fi, and the grill’s IP entered in Settings. That’s it.
Does it work with stock GrillEye firmware?
No. Grilly talks to the local HTTP API that the free-grilly firmware exposes; the stock firmware doesn’t offer it.
Do I need an InfluxDB server?
No, it’s optional and off by default. Grilly records temperatures on-device; InfluxDB is only for long-term history if you want it.
Is it really free?
Yes. There are no paid features. There’s a friendly tip jar if you’d like to support development, but it unlocks nothing, it’s purely a thank-you.
