There’s a possible fault on mine, the ‘sw’ connection only works every 2nd toggle to switch and the voltages dont seem right. ie
h = on sw=3.25v
l = off sw=0v
h = on sw=3.0v <-----
l = on sw=0.125v <------
h = on sw=3.25v
l = off sw=0v
repeat…
SW line is connected to my bike alarm/ign. control is via pc123 opto-coupler as the output is 84v. vesc GND and SW are connected direct to opto-coupler.
I have already had 1 runaway event with it jammed at 100% throttle on my 3kw bike, thankfully bike was on a stand. unplugging throttle did not stop this...and it would not turn off I had to find my phone to disable the bms.

Hi Read Datasheet for limitation of pc123 max 70V and do not forget bouncing voltage between VDC an GND Vceo-? Connect it to 5V and GND.
I have a pair aswell, it works properly with App settings -> Shutdown Mode ALWAYS_OFF and TOGGLE_BUTTON_ONLY
With the timed ones it doesn't seem to work/needs to be switched off 2 times for whatever reason.
