During riding, the power is reduced to 0, and it can't be recovered if you continue pedaling。 If you stop riding for 1 or 2 seconds, you can recover

you can check cfg file and csv file as below.

vpower_cfg.zip

I use magene speed sensor S3+

The speed in the csv is the value received from speed sensor. You don't need to add one by one, use a 5 km/h interval like the example, the program will calculate the intermediate values.

If you want to multiply the power, just multiply the values in the power column, for example:

Speed (Km/h),Power (W)
5,150
10,300
15,450
20,625
25,800
30,1000
35,1150
40,1400
45,1625
50,1875
55,2150
60,2450

Use the default wheel circumference (2.105 is a 700x23 tyre) and the speed from sensor probably won't be above 60 km/h.

I don't know if this is related to the issue, but try fixing that first, then if the issue persists we can do other tests.

thanks. Ok, I will test it. how many wheel circumference should I use by 27.5*1.75?

please ignore this report, I check it use app of sensor provider which communicate by Bluetooth, speed reduce to 0 too.

So this is issue of speed sensor.

The circumference is around 2.115 but such a small difference is insignificant since your goal is to overestimate power.

But anyway, don't increase wheel circumference, just multiply power values in the csv.

please ignore this report, I check it use app of sensor provider which communicate by Bluetooth, speed reduce to 0 too. So this is issue of speed sensor.

Try using an USB extension cable to put the stick closer to the sensor and replace the battery.
