TidalFit Swim Spas WiFi Control Kit
Turn your phone into the spa control system. Adjust temperature, lighting, jets, filtration schedules and more from anywhere with an internet connection — this is the factory-style WiFi control kit for TidalFit Swim Spas on the current control system.
What’s in the Kit
- WiFi module (connects at your spa pack)
- Home transmitter + power supply
- Quick-start guide and the free iOS / Android app
Compatibility
- Fits: TidalFit Swim Spas whose spa pack label reads in.ye, in.yt or in.xe — including every WaVS True Variable Speed swim system
- TidalFits with a BP or MBP pack use the TidalFit WiFi Control Kit for BP systems instead
- MVS504SZ-pack TidalFits: no WiFi option without a retrofit — see our WiFi retrofit help
The module plugs into the accessory port on your spa pack; the home transmitter sits near your router. No wiring through the cabinet.
✅ Not Sure It Fits? Verify Before Ordering
TidalFit Swim Spas parts vary by model, model year and generation — the model year alone does not settle it: match your spa pack label.
To help us identify the correct replacement, please send clear photos of:
- Your spa pack / control system label
- Your spa serial number sticker
- Your topside control panel
EZ Hot Tub Parts can help confirm fitment before you order and help reduce costly returns.
TidalFit Swim Spas whose pack label reads in.ye, in.yt or in.xe — that includes all WaVS True Variable Speed swim systems, which run on this control platform. BP/MBP-pack TidalFits use the other TidalFit WiFi kit; MVS504SZ-pack units have no WiFi option without a retrofit. The pack label is definitive.
Home WiFi, a power outlet near your router for the small transmitter, and the free iOS or Android app. Setup takes a few minutes; the app walks you through pairing.
Yes — once paired, the app works from anywhere with an internet connection: pre-heat before you get home, check the water temperature from vacation, or adjust filtration cycles from the office.
