Ondilo ICO Pool Smart Water Monitor
⚠ Similar names, different products: ⚠ TWO VARIANTS, ONE NAME, $50 APART — and Ondilo's page sells them from a single product selector, so it is easy to buy the wrong one. The chlorine/bromine variant is SKU ICO-POOL-CHLORINE at $449 (this record); the salt variant is SKU ICO-POOL-SALT at $499. They are not cosmetic trims: Ondilo states that "For salt water pools, ICO also analyzes TDS (Total Dissolved Solids)", so the salt variant measures a fourth parameter the chlorine one does not. ⊕ The product is also named "ICO Pool" specifically — Ondilo's line naming distinguishes pool from spa elsewhere in its range, so a listing that says only "ICO" is not evidence of which device is in the box.

Before you buy
What do you need to make it work?
Same position — no Apple Home, HomeKit or Siri claim on the surface read, and no Matter claim either, so there is no protocol-level route to reason about. The radios Ondilo does state are Wi-Fi 802.11 b/g/n and Bluetooth LE 4.0+; neither is described as carrying a HomeKit or Matter stack, and a radio is not a protocol claim.[1]
Ondilo ICO Pool Smart Water MonitorGoogle Home
There is not enough model-specific evidence to draw a supported connection. Read the evidence and limits below.
Not established — and the one appearance of the word on Ondilo's page is a trap worth naming. "Google" occurs there only in analytics and font tags, in a reviewer's display name ("A Google User"), and inside one customer review reading "I wish it worked with Google, but it's still super useful". A customer's wish is not a maker's specification, and we treat it as neither: it is not evidence that Google Home is unsupported, and it is certainly not evidence that it is. Ondilo itself says nothing, so the question stays open.[1]
Ondilo ICO Pool Smart Water MonitorAmazon Alexa
There is not enough model-specific evidence to draw a supported connection. Read the evidence and limits below.
Not established. Ondilo makes NO smart-home platform claim on the only first-party surface available — the page source was searched by keyword for Alexa, Google Home, Google Assistant, Apple Home, HomeKit, Siri, SmartThings, Home Assistant, Matter and IFTTT, and "Alexa" returned zero occurrences. That is qualified silence under the spec-less-vendor rule: no compatibility list means nobody has answered the question, not that the answer is no. Everything runs through Ondilo's own ICO app. ⚠ Note this is a Wi-Fi device with a cloud app — a shape that often does carry a voice integration — so the silence here is more surprising than it would be on a Bluetooth-only product, and worth asking Ondilo about directly before buying on that assumption.[1]
Ondilo ICO Pool Smart Water MonitorSmartThings
There is not enough model-specific evidence to draw a supported connection. Read the evidence and limits below.
Same position — SmartThings is not named anywhere on the surface read.[1]
Ondilo ICO Pool Smart Water MonitorHome Assistant
There is not enough model-specific evidence to draw a supported connection. Read the evidence and limits below.
Not established, and the page we can point at never raises the subject. Ondilo's own US product page describes the probe and its app and names no smart-home platform anywhere on it — not Home Assistant, and not Alexa, Google, Apple or SmartThings either. Buyers in the reviews underneath ask the company for voice control, which tells you what customers want and nothing about what the product does. So this is a maker who has not addressed the question rather than one who has answered it, and only one first-party page was reachable here, which this record does not stretch further than it goes.[1][4][5]

Plans and ongoing costs[1][5]
✓ Works without a subscription: Yes.
Vendor account required: Not established — we have not sourced this yet.
Ondilo denies a fee in two places on its own page: the price carries the label "No subscription fee" printed directly beside the $449 figure, and its questions section states the app "is completely free to download and use, with no subscription fees". ⭐ We record no subscription on the strength of that EXPLICIT DENIAL rather than on silence — and here the denial is doing commercial work, since it is printed as a selling point next to the price. ⊕ Worth stating on this shelf, because it is where the category's money usually hides: no plan gates the readings, the history or the app's recommendations on the evidence we read. The consumables are the probes and the battery, both covered by warranty terms Ondilo states inconsistently — see the lifecycle section below.
Maintenance and offline use
- Batteries: rechargeable lithium-ion (built-in)
- Works without the internet: Not established — we have not sourced this yet. It does not mean the product fails without the internet.
- Ondilo publishes a recharge interval rather than a battery life, and states it twice in compatible terms: the specification table reads "Rechargeable Lithium-ion battery (charging required every 6+ months)", and the prose reads "The long-lasting rechargeable battery typically needs charging just once or twice per season". ⊕ We deliberately publish no service life for the battery — a recharge interval is not the same thing, and Ondilo gives no figure for how many seasons the cell itself lasts. ⚠ That distinction matters here because the battery is named as a separately-warranted part, which is the maker's own signal about what wears out. Water rating is stated as "IP68 certified". Physically it is small — "4.3 × 5.9 inches (diameter × height)" and "0.7 lbs" — and Ondilo describes the sensors as "plug-and-play", meaning you can change them yourself. It takes a reading every hour: it "measures pH, ORP (oxidation-reduction potential), and water temperature every hour".
- Security updates: No security-update support date is on record for this model yet. We haven't yet checked whether Ondilo publishes one, so this is a gap in our research — not a statement about the manufacturer.
The catch
It measures the water well and tells nothing else in your house about it. Ondilo names no smart-home platform at all — no Alexa, no Google, no Apple Home, no SmartThings, no Matter — so $449 buys a dedicated app, not an integration, and the only mention of any platform on the entire page is a customer wishing it worked with Google. ⚠ The second catch is one Ondilo creates itself: its own page states the warranty two incompatible ways, "1 Year Limited Warranty" in the specification table against "2-year warranty on the main ICO device" in the FAQ. On a sensor that lives in chlorinated water, that is the term you would most want to be sure of, so get it confirmed in writing rather than picking the friendlier number. ⊕ Two practical notes rather than catches: buy the right variant — chlorine/bromine at $449, salt at $499, and only the salt version measures TDS — and expect to fish it out to charge it once or twice a season.
Who it's for
A pool owner who wants hourly pH, ORP and temperature readings with dosing guidance in an app, and who values that the device simply drops into the pool or skimmer with nothing to install and no plan to pay for. It suits someone whose sanitizer is chlorine, bromine or salt — Ondilo covers all three, unlike some monitors on this shelf — and who is happy for pool chemistry to live in its own app. Not for anyone who wants water data to reach a voice assistant, a dashboard or an automation, and not for a buyer who needs the warranty terms to be unambiguous before spending $449.
