The short answer
Any Bluetooth FTMS trainer will work — that covers virtually every smart trainer released since 2018, from Wahoo, Tacx (Garmin), Elite, Saris, Kinetic and others. WattLog.pro reads power, cadence and speed, and sets resistance for ERG and route simulation.
If your trainer pairs with Zwift, TrainerRoad, Wahoo Systm or Rouvy over Bluetooth as a smart trainer, it will pair with WattLog.pro. Trainers those apps reach only over ANT+, or over a maker's own protocol, are the exception — see below.
Tested by us
The hardware we have actually ridden with, on real sessions — not a compatibility promise copied from a spec sheet.
| Device | Type | What we ran |
|---|---|---|
| Wahoo KICKR CORE (v1) | Smart trainer (FTMS) | ERG workouts, route simulation, free ride |
| Favero Assioma PRO | Power meter (Cycling Power) | Power and cadence during workouts |
| Garmin HRM-Dual | Heart-rate strap | Heart rate and RR intervals |
Expected to work — direct drive
| Trainer | Brand | Power | Resistance control | Basis |
|---|---|---|---|---|
| KICKR CORE | Wahoo | Yes | Yes | Tested |
| KICKR / KICKR BIKE (2018+) | Wahoo | Yes | Yes | Maker's FTMS support |
| NEO 2T / NEO 3M | Tacx (Garmin) | Yes | Yes | Maker's FTMS support |
| Flux S / Flux 2 | Tacx (Garmin) | Yes | Yes | Maker's FTMS support |
| Suito / Suito-T | Elite | Yes | Yes | Maker's FTMS support |
| Direto XR | Elite | Yes | Yes | Maker's FTMS support |
| H3 | Saris | Yes | Yes | Maker's FTMS support |
Expected to work — wheel-on
| Trainer | Brand | Power | Resistance control | Basis |
|---|---|---|---|---|
| KICKR SNAP | Wahoo | Estimated | Yes | Maker's FTMS support |
| Qubo Digital Smart B+ | Elite | Estimated | Yes | Maker's FTMS support |
| M2 | Saris | Estimated | Yes | Maker's FTMS support |
* “Estimated” power = calculated from speed and resistance rather than measured by a strain gauge.
“Expected” means the maker documents Bluetooth FTMS for that model. We read the standard, not the brand — but only the row marked Tested has been ridden by us.
Older and ANT+-only trainers
Trainers made before FTMS — the first KICKR generations (2014–2016), Tacx Vortex and Genius Smart, and similar — speak their maker's own Bluetooth protocol. WattLog.pro does not implement those, so they will pair but not take resistance commands, if they pair at all.
My trainer isn't on the list
The tables above are not a test log: apart from the row marked Tested, they list models whose makers document Bluetooth FTMS. If your trainer supports FTMS — which covers the vast majority of smart trainers made since 2018 — it will work.
Not sure? Send us the model and we'll check it. If it needs a fix on our end, we'll build it.
What about ANT+ trainers?
WattLog.pro uses Bluetooth only. Most modern smart trainers broadcast on ANT+ and Bluetooth at the same time — if yours does, use the Bluetooth side and it will work. Trainers that speak ANT+ only, usually older ones, are not supported.
