How it works
Your valves only speak Bluetooth. HappyPlant gives them the internet — on-demand control and visibility from anywhere, and, if you connect your Hydrawise schedule, a system that makes the schedule’s intent become real water and tells you the truth about it afterward.
The path of a watering
- 1
A watering is asked for — by you, from anywhere, or by your schedule.
Tap Run on any valve from wherever you are — SF, while the valves are in LA — or connect your Hydrawise schedule (optional) and HappyPlant watches each zone’s watering windows for you.
- 2
A bridge carries the run to the valve.
Small bridges placed around your property connect to your NODE-BT valves over Bluetooth. Coverage is redundant by design: if one bridge is busy or offline, another in range carries the run, and adding a bridge simply extends reach and resilience.

A late start still gets the full watering.
If a valve connects eight minutes into a twenty-minute window, it still gets its full twenty minutes. HappyPlant tracks what every zone is still due and keeps at it until it’s delivered — a short run never gets silently shrugged off.
- 4
The valve’s own log settles the books.
After each run, HappyPlant reads the valve’s internal run log — the hardware’s own account of what actually happened — and compares it with the schedule. Scheduled vs. delivered, per zone, per day.
- 5
When something’s wrong, your phone knows first.
A zone that should be watering and isn’t, a valve that came up short, a bridge that dropped offline, a valve refusing its passcode — each sends a push alert to your phone that says what’s actually wrong and what to check, not a generic red dot. You’re hundreds of miles away; the point is you don’t have to wonder.
What if the internet dies mid-watering?
Nothing floods. Every run is sent to the valve with a fixed run time the valve’s own timer enforces — even if the cloud, your WiFi, and every bridge disappear at the worst possible moment. The system is built so that its worst failure mode is a zone finishing its scheduled watering and stopping. And the bridges keep themselves up to date on their own — no ladder, no truck roll.
What you need
- Hunter NODE-BT battery valves (the ones the Hunter app talks to).
- WiFi at the property.
- Optional: a Hydrawise account. Without it you still get on-demand control, visibility, and watering history from anywhere; with it, HappyPlant runs and verifies your whole schedule.
- One bridge per Bluetooth coverage area — a bridge covers the valves within radio range, and more bridges mean coverage and redundancy.
