Solar scheduling, on-device
Anchor any program to local sunrise or sunset with an offset. Hydrega computes the times itself from your location — accurate to about a minute, adjusting all year. No cloud needed.
Water smarter · waste less
The sprinkler controller that waters with the sun — and never stops when the Wi-Fi does.
Hydrega schedules your garden around real local sunrise and sunset, sequences every zone safely, and skips watering when rain is on the way. Control it from your phone when you want — but it keeps your garden alive whether or not the cloud is reachable.
Works fully offline · No account required · OTA updates
- Runs offline, forever
- Sunrise & sunset aware
- Rain-skip built in
- Wi-Fi + Bluetooth setup
Why Hydrega
Everything a modern garden controller should do
Reliable enough to trust with your water and your power — clever enough to save both.
Safe multi-zone sequencing
Programs run one zone after another, never more than your power supply can drive. A current budget and a hard per-run cutoff keep your water and wiring safe.
Rain-skip & rain sensor
Skip scheduled runs when rain is forecast, and wire in an optional rain sensor for ground truth. Stop watering the lawn during a downpour without lifting a finger.
Seasonal adjust
Scale every run by a percentage and limit programs to a date range — dial watering down in spring and up in the height of an Iberian summer, without rebuilding schedules.
Control from anywhere
Use the iOS, Android or web app on your home network — or securely over the internet when you pair the device. Same controls either way; the app prefers your LAN and falls back to the cloud.
Over-the-air updates
New features and fixes arrive as signed OTA updates with safe rollback. Your controller gets better over time and never needs to be unplugged to update.
Setup in minutes
From box to first watering in four steps
No hub, no subscription, no account required to get going.
-
Wire your valves
Connect your 24VAC solenoid valves to the labelled zone terminals and power it up.
-
Connect over Bluetooth
Open the app and pair over Bluetooth — or use the built-in Wi-Fi setup page. Hand it your Wi-Fi if you want remote access.
-
Set location & zones
Pick your location once so sunrise/sunset can be computed, name your zones, and set your current budget.
-
Build a schedule
Choose a fixed time, sunrise or sunset anchor with an offset, add seasonal adjust, and you're watering.
Zones & scheduling
One controller, every program your garden needs
Each schedule picks a single start anchor — a fixed time, sunrise, or sunset — and runs its zones in order. Want morning spray and an evening drip top-up? Create two schedules. Hydrega resolves real local times for you and respects daylight-saving changes automatically.
- Sunrise anchor for spray zones. Finish around first light so foliage dries and fungal disease is suppressed (default: 30 min before sunrise).
- Sunset anchor for drip zones. Root-zone watering that sits overnight without evaporating — ideal for the Iberian heat.
- Sequential by default. Zones run one at a time with a settle delay; concurrency only up to your current limit.
- Hard runtime cutoff. Every zone has a safety maximum so a stuck schedule can never flood your garden.

FAQ
Questions, answered
Does Hydrega need an internet connection?
No. Once a location is set, sunrise and sunset are computed on the device and your schedules run autonomously — forever — with no cloud. Internet only adds remote control from anywhere and weather-based rain skip. If your Wi-Fi or our cloud is down, your garden still gets watered.
How does sunrise and sunset scheduling work?
Set your location once. Hydrega computes local sunrise and sunset on the device using the NOAA solar equations — accurate to about a minute. Anchor a program to sunrise or sunset with an offset (for example, start 30 minutes before sunrise). The times shift correctly through the year and across daylight-saving changes.
Which valves and wiring does it support?
Standard 24VAC solenoid valves on the mains/USB-powered models, and latching solenoids on the battery model (so it draws no holding current). Models come with 2, 4 or 8 zones, plus an input for an optional rain sensor.
Do I need an account?
No. Setup and local control need no account at all. Create one (sign in with Google) only if you want to control your controller over the internet. We never store your Wi-Fi credentials — those stay on the device.
Where is Hydrega available?
Our first market is Iberia — Portugal and Spain — with the app and site in English. Hydrega works anywhere with 2.4 GHz Wi-Fi or Bluetooth, since solar times are computed from your location on-device.
