The short answer
Any Bluetooth Smart trainer that exposes power data will work. This includes virtually every smart trainer released in the last 5 years from Wahoo, Tacx (Garmin), Elite, Saris, Kinetic, and others.
If your trainer connects to Zwift, TrainerRoad, Wahoo Systm or Rouvy via Bluetooth, it will connect to WattLog.pro.

My trainer isn't on the list
The list above is only what we've personally tested or confirmed from Founding Rider reports. If your trainer supports Bluetooth Smart and broadcasts over the FTMS (Fitness Machine Service) profile — which covers the vast majority of smart trainers made since 2018 — it will work.
Not sure? Send us the model and we'll confirm within 24 hours. If it needs a fix on our end, we'll build it.
What about ANT+ trainers?
WattLog.pro currently uses Bluetooth only. Most modern smart trainers broadcast on both ANT+ and Bluetooth simultaneously — if yours does, it will work. Pure ANT+-only trainers (usually older models) are not supported yet. ANT+ support is on the roadmap for a future release.
