Sutro shutdown: what the pool-monitor record establishes

Our Sutro record records an October 2025 shutdown with no documented local fallback. A secondhand monitor is not an established way to regain pool readings.

The evidence has a limit

The original research recorded a shutdown notice on Sutro’s own site. On 8 August 2026, both recorded Sutro sites failed to respond, including the notice previously cited. Those are dated observations; this rewrite does not turn them into a new live service check.

A vanished page cannot provide the same proof as a readable company statement. The record preserves that limit alongside the shutdown history. It does not document a recovery service, third-party takeover or local reading mode.

Platform access is a separate question

The former Sutro compatibility material described Alexa and Apple HomeKit as roadmap items rather than established shipped functions. Its Google route used conversational Assistant Actions, the feature class Google retired in June 2023.

The help desk is no longer readable in the record, so the platform answers remain unknown rather than being strengthened into flat exclusions. A roadmap item was never a purchase promise.

What to check in another monitor

WaterGuru Sense is a separate researched product, not a recovery route for Sutro. The profile covers the SENSE 2, which WaterGuru’s own store no longer sells; the store now sells the SENSE 3 in its place. Its recorded FAQ states no subscription or ongoing software-service charge. The monitor still has recurring physical costs: measurement cassettes and four C batteries. The documented refillable cassette covers about 60 reads; cassette life varies by type and use, so obtain a current consumable quote for your season.

WaterGuru requires usable Wi-Fi at the pool. Its recorded Alexa skill is for asking for readings, not automation triggers. Siri app shortcuts are not Apple Home accessories. WaterGuru’s SmartThings and Home Assistant support remain unknown; the community Home Assistant add-on uses WaterGuru’s cloud and is not endorsed by either party.

WaterGuru also lost its Google conversational integration. That feature withdrawal is different from Sutro’s whole-service shutdown.

Ask about the service behind the hardware

The WaterGuru record’s latest lifecycle review describes an operating service, but no published service end date. A hardware warranty does not establish how long cloud readings will remain available. Its separate support site could not be read during that review, which limits the evidence further.

Before purchasing a cloud monitor, ask what readings remain available without internet access, where history lives, how consumables are supplied and what service commitment the manufacturer publishes. Do not treat an automatic chemistry reading as a substitute for the checks your pool’s maintenance instructions require.

Compare the documented dependencies in the pool directory and the exact platform route in the checker.
