After owning a Rise since June I first used the RS Toolbox, then tried the E-Steps so I could see other data on the same screen like HR, Gears,
ect. on the same screen as battery % and assist mode. On several rides the RS Toolbox info failed to appear on my Garmin and I had to power off/on my bike for it to finally appear. I switched to E-Steps and only after a few rides I ran into the same issue. No battery % or assist mode for my ride. Tried turning the bike off/on, Garmin off/on, restarting my ride on Garmin and still nothing. I think sometimes it depends on if you're riding in an area without good cell service.
Anyway, I since removed both of these apps (only used/had installed 1 at a time) and under sensors in my Garmin added/paired an Ebike sensor. It shows the battery %, assist mode as 0,1,2,3 instead of ECO, TRAIL, BOOST. It also shows cadence like the RS Toolbox does. I've had 1 ride so far and it has connected every time without issue, unlike the previous apps.
Just wanted to throw out another option other than the RS Toolbox.
