FulGaz now offers Power Match support for external powermeter users.
If you'd like to use the power data from your powermeter, but still experience the automated resistance controls from FulGaz (either in ERG mode for training or in regular ride mode) you can now do so connecting both your devices on the initial FulGaz connections screen!
Connect your power meter under the "Power" option.
Connect your smart trainer under the "Trainer Resistance Control" option.
Cadence can be read from either device.
