Zooz Titan Water Valve Actuator (ZAC36)

Compiled by SmartHomeWorkflow Research · Zooz · Water Protection & Plumbing · Price: Zooz's own product page carries no price and routes buyers to retailers, so no price is recorded rather than importing a reseller's number. The three channels Zooz names itself are The Smartest House, Amazon and Amazon.ca.

Before you buy

What do you need to make it work?

No hub for the device alone

Choose a platform above for its connection. A hub can be optional for the device itself and required for a platform or automation.

Only for the smart half, and Zooz draws the line precisely: 'The ZAC36 does not need to be connected to a hub to function with the attached water sensor; however, to control the device remotely, you would need a Z-Wave hub.' The included wired probe closes the valve on its own. Everything else — app control, scheduling, freeze automations, notifications, reporting to other sensors — needs a Z-Wave hub. Zooz names its compatible hubs: its own Z-Box Hub (recommended), SmartThings (driver install required), Home Assistant via Z-Wave JS, Hubitat 2.2.9 or higher, HomeSeer, Homey, Ring Alarm, Alarm.com automation hubs, Ezlo Plus and Ezlo Secure, and Indigo — with the caveat that Indigo supports no S2 security.[1][4][16][18][22][26]

Setup and sources

Apple Home

No path. Apple Home speaks Matter, Thread and HomeKit and has never spoken Z-Wave; Apple appears nowhere in Zooz's compatible-hub list, and Zooz's 'or other smart speaker' answer covers the HomePod case. Recorded from the protocol reality plus Zooz's own hub list, which omits Apple entirely — this is a Z-Wave device and Apple Home is not a Z-Wave controller.[2][16][22][26]

Google Home

Covered by the same Zooz sentence and the same reasoning as Alexa: no Z-Wave radio in a Google speaker, so no direct path. Any Google visibility comes from whichever Z-Wave hub you pair the Titan to.[2][16][22][26]

Alexa

Zooz answers this one directly and in the negative: 'Can I connect the Titan directly to my Amazon Alexa, Google Home, or other smart speaker? No. Smart speakers like Alexa or Google are not equipped with a Z-Wave chip and are not Z-Wave gateway controllers.' There is no direct path from this device to Alexa. If Alexa ends up able to say anything about your water valve, that is your Z-Wave hub's integration doing the work — a SmartThings or Ring Alarm hub bridging it — and what Alexa then exposes is the hub vendor's decision, not Zooz's.[2][16][22][26]

SmartThings

Zooz names SmartThings on its compatible-hub list and links a driver to install, and Samsung's own partner directory lists this actuator by its model number, so both companies say it works. The friction is stated up front: you install a driver rather than the device being recognised out of the box, and a SmartThings hub with a Z-Wave radio is required.[1][14][16][19][22][24][26][29]

Home Assistant

Zooz names 'Home Assistant (Z-Wave JS)' on its compatible-hub list; Z-Wave JS is Home Assistant's official Z-Wave integration and runs entirely locally against your own Z-Wave stick or controller. This is the configuration with the least between you and the valve — no vendor cloud on either side.[1][16][22][26]

Plans and ongoing costs[1][7][11][16][22][26]

? Works without a subscription: Not established — no source we accept has addressed fees for this product in either direction.

Vendor account required: No — no vendor account is involved.[1][11][16][22][26]

Not established, and the honest answer is a step back from what this page used to say. Zooz's page for the ZAC36 mentions no fee at all, and a page that says nothing about a subscription is not the same as one that says there is none. WHAT WAS CHECKED on 2026-08-26: the product page again, which contains no occurrence of subscription, free app, monthly, fee or cloud; and Zooz's support site, which refused to serve us even though its own rules permit it. ⚠ Everything known about this device points AWAY from a fee — it is a Z-Wave actuator with no vendor servers in the path — but that is reasoning rather than a source, and the local-operation facts on this page already stand on their own evidence. What would settle it: any statement from Zooz that the app or the device is free to use.

Maintenance and offline use[3]

Who it's for

Households that already run Z-Wave — SmartThings, Home Assistant, Hubitat, Ring Alarm or Zooz's own Z-Box — and want an actual shutoff rather than another sensor that beeps. It fits anyone who wants the valve to close when the network is down: it is the only one here whose failsafe needs no hub, no cloud and no subscription. It is the wrong pick if you own no Z-Wave hub, if there is no outlet near your shutoff valve, if your main is a gate valve rather than a quarter-turn ball valve, or if you want whole-home leak detection out of one box.

  12. [12] Zooz's first-party ZAC36 LR quick guide and user manual, downloaded and read again on 2026-09-18, and every specification this record cites from it still reads the same word for word: 'Model Number: ZAC36 LR'; 'Z-Wave® Region: US / CA / MX'; 'Power: 12 V DC (1 A) power supply (included)'; 'Temperature Sensor Range: -40° to 257° F'; 'Sound Indicator: up to 85 dB'; 'Z-Wave® Range: Up to 400 feet line of sight (up to 1300'; 'Operating Temperature: 14-122° F (-10-50° C)'; 'Installation and Use: Indoor & outdoor (Ip66)'; 'Standby Power Consumption: 0.12 W'; 'Full Operation Power Consumption: 8.4 W'. The features list still carries 'Use it offline with the included leak sensor probe', 'Built-in temperature detection for instant freeze detection', 'Retrofit installation with no tools required' and 'S2 Security and SmartStart for easier inclusion', and step 5 still describes connecting the offline leak-detector probe to the jack next to the power connector, where 'It will trigger the valve to close whenever a leak is detected'. The version and frequency half of the research note was re-read the same day on Zooz's product-page FAQ, which still answers 'The Titan is currently available in 908.42 MHz (US) frequency only. We do not currently have plans to release the ZAC36 in EU or AU frequency' and 'Yes, the VER 2.0 ZAC36 supports Z-Wave Long Range (ZWLR).' — Read on the maker's own site, verified 2026-09-18
