Subscription reality
✓ Works without a subscription: Yes.
No subscription, but measurement cassettes cost ~$120–240/yr — a consumable, not a fee
Maintenance reality
- Batteries: D x4 — expect roughly 6 months per set
- Cloud dependence: Yes — a server shutdown would degrade or brick this device
- Cassette replacement every 1–2 months in season; skimmer-mounted
The catch
The cassette consumables (about monthly) are the real cost of ownership — budget for them. Current SKUs are the SENSE 2 and SENSE 3.
Who it's for
For pool owners who want daily water chemistry readings without test strips — and one of the few consumer water monitors still operating after the Sutro shutdown.
