Hello!
I've recently rebuilt an old hybrid bike into an ebike with parts from Grin and I was hoping to use it as a winter bike in a climate with snow and salt and this has led to a real headache when it comes to finding a good way to add torque sensing capability to the bike. I've tried the Sempu BBs in the past and while they work great no matter how much maintenance I did after every ride they ended up being completely gunked up by the end of the winter and spending $150+ seasonally to replace one component isn't great. I've settled for a cadence sensor in the meantime but I've continued looking into alternative solutions like cranks with torque sensors built-in or the BEAMts system which both have been dead-ends.
As such, I was wondering if it might be feasible to use a power meter and have it stream data via ANT+ or BT to a microcontroller and have it use the data from the meter to act as a torque sensor and have the data translate over to whatever protocol Grin's Cycle Analyst accepts for PAS/torque input.
I was curious if this had been attempted before and if it would even be feasible considering the potential latency and the semi-proprietary nature of of most power meters out there. Any insight or suggestions on this matter would be much appreciated!
