Controllers, Timers & Sensors

Name: RainWell Irrigation Controllers & Timers
Brand: RainWell

From single-tap water timers to 32-station modular controllers – Bluetooth, Wi-Fi, 4G and solar – plus rain and soil-moisture sensors.

T01 Water Timers

T01Q / T01RQ battery timers for taps and drip lines.

CB01 Bluetooth single station controller

CB01 Single Station

9 V battery controller with latch valve, Bluetooth on CB01B.

CA08 (8 zones)

AC/DC indoor controller, 6 start times per zone, Wi-Fi option.

CA12 / CA32

12-zone 4G/Wi-Fi and 16-32 zone modular controllers.

CJS-4G Solar

Solar + Li-ion 4G controller, IoT platform, valve-level telemetry.

Direct answer: choose a water timer (T01) for one tap, CB01 for one valve zone without mains power, CA08 for a house or small park with 24 V valves, CA12/CA32 for 12-32 zone sites with remote control, and CJS-4G for off-grid farms where every valve reports back to the cloud.

Controller	Zones	Power	Connectivity	Typical use
T01Q / T01RQ	1-2 outlets	2-3 × AA	LCD programming	Tap, drip kit, balcony
CB01 / CB01B	1	9 V battery (13-14k cycles)	button / Bluetooth 5.0 + app	Single zone, no mains
CA08	8 + master	220 V AC → 24 VAC / 9 V DC	optional Wi-Fi module	Residential / small park
CA12	12 + master	mains	4G or Wi-Fi + app	Municipal / remote sites
CA32	16-32 modular	220 V AC	optional Wi-Fi module	Large parks, sports
CJS-4G	2 outputs (one-drive-two)	solar + Li-ion ≥4000 mAh	4G IoT platform	Off-grid agriculture

Which irrigation controller works without mains power?

CB01 (9 V battery, one latching valve) and CJS-4G (solar + Li-ion, 4G reporting, ≥30 days without sun). The T01 water timers also run on AA batteries.

Can I control the controller from my phone?

CB01B pairs over Bluetooth 5.0 (up to 35 m open field); CA12 offers 4G or Wi-Fi remote control from anywhere; CA08/CA32 accept a Wi-Fi module; CJS-4G reports to an IoT platform.

Do the controllers support rain sensors?

Yes – CA-series and CB01 controllers pause schedules when paired with the SR rain sensor or SL soil-moisture sensor.
