Tropic Seas 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 Tropic Seas 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: Tropic Seas Spas whose spa pack label reads in.ye, in.yt or in.xe — the in.ye-equipped build (supplied to Hawaii 2021 and newer; identify by the pack label, not the year)
- Tropic Seas with a BP or MBP pack (MBP501 / MBP501UX, the mainland standard) use the Tropic Seas WiFi Control Kit – CMS instead
- 2013–2015 Tropic Seas (MVS504SZ pack): 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
Tropic Seas 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.
Tropic Seas Spas whose spa pack label reads in.ye, in.yt or in.xe — the in.ye-equipped build, which Tropic Seas supplied mainly to Hawaii from 2021. Mainland Tropic Seas run BP/MBP packs and use the CMS kit; 2013–2015 MVS504SZ spas 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.
