Hey @jjnapp,
The pairing procedure for the Concept2 ERG is to pair to the power meter itself by making sure the bike is set to “ANT+ PWR profile. It should list as just “Power Meter”.
We are unable to pair to the ERG profile because we do not have one in the office to test with 
.
Would you mind sending screenshots of the Device Screen and of the “No Power” message in the workout page? These may be helpful in assessing the situation. It is possible that the bike is running outdated firmware. Is it possible for you to check the firmware version and/or update the gym bikes?
