Easy·care by Waterair

Big thanks to @Yyrkoon94 for the pioneering work on ha-easycare-waterair — that plugin proved the Waterair API could work with Home Assistant.

After a few months of using it, I ran into a number of limitations that pushed me to rewrite the integration entirely from scratch:

Token expiring every ~2 months with no automatic renewal → regular manual reconnection
YAML-only configuration (no UI)
Non-standard HA architecture (no ConfigEntry, no DataUpdateCoordinator)
No control over the pump or equipment** (read-only)

So here's my Home Assistant integration for pools running the easy·care by Waterair ecosystem (WATBOX + BPC + AC1, plus the optional LR-PR pressure sensor).

This integration is unofficial and independently developed. Waterair is not affiliated with this project.

What it does

It connects to the Waterair cloud over OAuth2 and exposes your whole setup in HA.

Reading

Water temperature, pH, chlorine (Redox/ORP)
AC1 analyser battery level
Filtration pressure and battery level (if an LR-PR sensor is present)
Current filtration mode (AUTO -2h / AUTO / AUTO +2h / On / Off / Prog)

Control — the big one, and what the original integration couldn't do:

Full filtration control — switch mode (AUTO ±2h / forced On / Off) right from HA, pump included
Filtration Boost (4h, 12h, 24h, 36h, 48h, 72h) — the real Waterair Boost, with a remaining-time sensor and two-way sync with the app
Spotlight and step lighting (on/off, 1h–6h duration)

What HA adds on top of the mobile app

This is where it gets interesting

Treatment & pool alerts

Pool action alerts (calibration required, wintering, chlorine treatment…) are translated and pushed automatically as persistent HA notifications as soon as a new event appears — no need to open the app to know an action is expected. They clear themselves once the condition is resolved.

Filtration schedule sensors

Three sensors computed in real time from the BPC programme:

Daily filtration duration (adapts to water temperature)
Next start / next stop → perfect for automations

Energy monitoring

Enter your pump's rated power (e.g. 150 W) and get:

Instantaneous power (W)
Cumulative energy (kWh) → drops straight into the HA Energy dashboard

Firmware update notifications

The integration detects available software updates for your BPC, AC1 and LR-PR modules, exposed as native HA update entities — visible under Settings → Updates. Notification only; the install itself stays on the Waterair side.
