Sutro Pool Monitor

Compiled by SmartHomeWorkflow Research · Sutro · Smart Pool · Price: unknown — no current price exists. The product is discontinued and its service shut down in October 2025, leaving the devices permanently inoperable, so there is no price to publish and nothing a buyer could purchase.

Sutro shut down in October 2025 and its servers are gone, so every monitor is permanently inert. Re-checked on 8 August 2026: both of Sutro's websites are off the air entirely, and even the shutdown notice we originally cited has gone with them. Sutro ceased operations in October 2025 and shut its servers. Every device is inert. Do not buy one secondhand at any price.

Before you buy

What do you need to make it work?

Equipment requirements need a check

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

One device can provide more than one role. These are setup requirements, not a shopping list of separate purchases.

What could you do with this?

Put its functions to use.

Research, not hands-on testing

Start with a documented control or event. The selected connection shows what is confirmed for that platform.

We have not established a control or event to illustrate for this product. Check the connection and equipment information above.

A documented control or event is one part of a setup. It does not by itself establish a complete automation.

The functions, side by side

What can you use, and where?[11]

A platform connection does not confirm every function. Controls and reported events are shown separately from what an automation can use.

Reported events

Individual function comparisons are not available. The control and event summaries above distinguish an unanswered question from a documented absence.

Listed device functions are established from vendor documentation. An ability missing here is unestablished, not necessarily absent.

EcosystemSupportThe catch
Amazon AlexaInconclusiveWe researched this and the evidence doesn't settle it — the catch explains why[16]Not established. Our answer came from a Sutro support article we can name but cannot link, because Sutro's help desk will not open for us. It makes little practical difference: Sutro ceased operations and every monitor went inert after 2025-10-31, so there is nothing here to connect to Alexa whatever the article said. Do not buy one.
Google HomeInconclusiveWe researched this and the evidence doesn't settle it — the catch explains why[16]Not established. Sutro's help desk will not open for us, so the article our answer came from is not something you can read. What is not in doubt is the outcome: the only Google route Sutro ever described was an old Assistant voice action of a kind Google retired for everyone in June 2023, and Sutro has since ceased operations with every monitor inert after 2025-10-31. Do not buy one.
Apple HomeInconclusiveWe researched this and the evidence doesn't settle it — the catch explains why[16]Not established. Our answer came from a Sutro support article we can name but cannot link, because Sutro's help desk will not open for us. In practice it is moot: Sutro ceased operations and every monitor went inert after 2025-10-31, so no Apple Home or Siri path could work now regardless. Do not buy one.
SmartThingsInconclusiveWe researched this and the evidence doesn't settle it — the catch explains why[16]Not established. Our answer rested on a Sutro support article never mentioning SmartThings, and Sutro's help desk will not open for us, so neither you nor we can read it today. Either way the product is finished: Sutro ceased operations and every monitor went inert after 2025-10-31. Do not buy one.
Home AssistantInconclusiveWe researched this and the evidence doesn't settle it — the catch explains why[16]Not established. Sutro's help desk will not open for us, so the article behind this answer is not something you can read. Home Assistant publishes no Sutro integration of its own, and the only route anyone built was a small community project — which has nothing to talk to now, because Sutro ceased operations and every monitor went inert after 2025-10-31. Do not buy one.

  1. [1] 2026-07 web research sweep (docs/02 catalog; primary sources cited there) — Checked a certification register, verified 2026-07-12
    Backs: Product identity, Protocols, Subscription, Batteries, Works without the internet
  2. [2] Sutro official shutdown notice (my.mysutro.com / mysutro.com) — company ceased operations; app + devices end-of-life after 2025-10-31; every unit inert — do not buy — Read on the maker's own site, verified 2026-07-15
  3. [3] Sutro official shutdown notice (my.mysutro.com / mysutro.com), read 2026-07-15 — company ceased operations; app and devices end-of-life after 2025-10-31; every unit inert. Re-checked 2026-08-08: neither address answers at all; the server behind them is gone — Read on the maker's own site, verified 2026-08-08
    Backs: Market availability, Research status, Service status, Price
  4. [4] Sutro official support, 'Can I connect Sutro to other smart devices in my home?' (support.mysutro.com article 360047628013, last updated 2023-03-21; read from an archived copy taken 2025-08-07 because the helpdesk blocks automated readers): 'on our roadmap we're considering: Amazon Alexa, Apple Home Kit' — Read on the maker's own site, verified 2026-07-21
  5. [5] Sutro official support article 360047628013 ('Just say: "OK Google, talk to my Sutro Smart Home."' — a conversational-Action invocation; Google sunset conversational Actions June 2023, the same retirement the waterguru-sense record documents). Tension between Sutro's stale claim and Google's platform retirement recorded honestly — Read on the maker's own site, verified 2026-07-21
  6. [6] Sutro official support article 360047628013: 'on our roadmap we're considering: Amazon Alexa, Apple Home Kit'; 'we're only working with Google Home at the moment' — Read on the maker's own site, verified 2026-07-21
  7. [7] Negative evidence, stated explicitly: Sutro's exhaustive smart-device article (support.mysutro.com 360047628013: 'Unfortunately, we're only working with Google Home at the moment') never mentions SmartThings — Read on the maker's own site, verified 2026-07-21
  8. [8] Sutro official support article 360047628013 (names no HA path) + no home-assistant.io Sutro integration page exists (checked 2026-07-21). A small community custom integration exists as a lead only — Read on the maker's own site, verified 2026-07-21
  9. [9] tools/link-check.mjs live run, 2026-08-12 — observed behaviour of the cited URL only; no vendor page or product fact was re-read., verified 2026-08-12
  10. [10] mysutro.com is the only source this record cites, and its robots.txt has been unreachable across repeated attempts on 2026-08-20 and earlier — ten recorded instances of the same failure. Under our standing rule, a site whose robots.txt cannot be read is not read at all, so no first-party Sutro page describing setup or connectivity could be reached. — Read on the maker's own site, verified 2026-08-20
    Backs: Required hub or bridge
  11. [11] Assessed 2026-08-22 against the surfaces this record already cites plus one new one. ① Sutro's own materials, as recorded on this record's five integration cells: Amazon Alexa and Apple HomeKit appear only as roadmap items being considered, the sole Google path was a legacy Assistant conversational Action ("OK Google, talk to my Sutro Smart Home") of the class Google retired platform-wide in June 2023, and SmartThings appears nowhere. ② The community Home Assistant integration ydogandjiev/hass-sutro, read 2026-08-22, whose own description does enumerate readings — "This component integrates Home Assistant with Sutro (https://mysutro.com/), a device that enables automated remote monitoring of the temperature as well as the chlorine/bromine, pH, and alkalinity levels" — and sets up "sensor" platforms for measurements, "binary_sensor" platforms for device state and "todo" platforms for recommendations. — Read what the other company publishes, verified 2026-08-22
    Backs: Capabilities
  12. [12] Attempted 2026-09-09 against https://mysutro.com/ — the only URL this record cites. We did not read it: mysutro.com/robots.txt could not be reached, and the policy's answer to 'I cannot tell whether you said no' is not to knock. That is the door, and it is retryable — a later run that reads mysutro.com/robots.txt successfully clears this. No other first-party route to these facts exists on this record. The Wi-Fi bands, the app's platforms and the power source all stay unrecorded — because the door was shut, not because nobody looked., verified 2026-09-09
  13. [13] No page was read. Every site this record cites was off limits on 2026-09-12: mysutro.com (its robots.txt could not be reached), my.mysutro.com (the same), support.mysutro.com (a refusal recorded 2026-08-26). home-assistant.io publishes no Sutro integration page, as this record's own integrations.home_assistant entry already records., verified 2026-09-12
  14. [14] lifecycle.service.note, as it read before 2026-09-15: Service shut down October 2025; devices permanently inoperable. Re-checked 2026-08-08: neither mysutro.com nor my.mysutro.com answers at all, meaning the server behind them is down entirely. The shutdown notice that was our evidence in July has disappeared with the rest of the site — which corroborates the claim rather than undermining it, but it does mean the citation is now an observation of absence., verified 2026-09-15
  15. [15] Sutro's own address behaves differently today than it has since this company shut down, and the change is about access rather than about the product. The plain address still gives an error before anything can be read. The www address now answers — it is being served by a shop platform — and what it answers with is an instruction telling every automated reader to stay off the whole site. So the door that was broken is now closed on purpose, and this record's facts still cannot be re-checked against Sutro's own words., verified 2026-09-17
  16. [16] support.mysutro.com, re-checked on the conduct register 2026-09-19: refused since 2026-08-22 and still refusing, so no automated reader may approach it and no page was requested. The five answers above all came from one Sutro support article, identified only by its number (360047628013), which is not an address that can be published., verified 2026-09-19
    Backs: Amazon Alexa compatibility, Google Home compatibility, Apple Home compatibility, SmartThings compatibility, Home Assistant compatibility
  17. [17] Looked on 2026-09-20 for another Sutro page carrying these facts. mysutro.com is the only address this record cites, and the file a site publishes to tell automated readers what they may read could not be read there — so, treating silence as a no, nothing was requested from the site. No other Sutro address appears anywhere on this record, and none was invented to fill the gap. No page carrying these facts was found., verified 2026-09-20
  18. [18] Asked again on 2026-09-27, before anything was read. Sutro's www address still tells every automated reader to stay off the whole site, its plain address still gives no answer we can read, and Sutro's help desk still turns our reader away, so nothing was requested from any of them. A search for another Sutro page carrying the product's identity, radio, subscription, local operation or batteries found none: every Sutro address this record has sits on those three sites, and no other Sutro address exists to try. An archived copy of Sutro's pages was not used, because our rules never read a refusing site's pages out of an archive., verified 2026-09-27
