This would be great feature as an emergency back up. So if your remote battery runs out or f it fails for some other reason you won’t have to push miles to get home.
Or just for 20-30km/h usage
This module works fine with all the other apps on the market. Juste a random bt module won’t work with metr. At least all the app I tried worked well with the module.
I made a video [ E-Skate Commute London n.1 part 1 - Canary Wharf Pier to Tower Hill DLR Station ] with the overlay and it looks good. I think it’s pretty much in sync, I had to slow down the downloaded webm file tough. I slowed it down to 93% of the original export speed, I think I have like 1-2 sec difference at the end but they’re almost in sync.
I probably need to accelerate and brake like 3 times in a row to set a “marker” that will let me synchronize the video with the log as my camera doesn’t timestamp the video (:/)
This is the css that I used: gist I used Premiere to cut the green by applying the Ultra Key video effect

I am afraid I will not do backup remote control feature, because BLE is not reliable enough and it is very dangerous. Better safe than sorry, just walk to a nearest bus station. Next time have spare batteries in your pocket 
I just added zoom feature for Desktop browsers
Click and drag to zoom in
Right click to zoom out
Zooming also affects map and summary values (avg / top speed / current etc.). Energy and distance is not affected but I will fix this bug in the future version.

Just received my module, unfortunately my board is down, but I’m anxious to give it a try, specially the video overlay
I flashed my firmware to the extended bldc tool. Now it shows this voltage https://metr.at/r/U0nVt Which is just multiplied by 10 for some reason
Because the voltage value is saved with different multiplier to the command buffer
ACKMANIAC_Sources/bldc-firmware/commands.c:181
We can ask @Ackmaniac to explain why he modified the multiplier

I cant write my settings with perimetr I can read it all but write says: communication failed
Yes i did it all
Is there a chance firmware did not upload properly? (for example you have Maytech VESC without bootloader). Otherwise please share your device model, OS version and perimetr app version.
I have updated the firmware again Still the same problem
I have a 4.12 vesc This one: https://www.ebay.at/itm/322491903214 iOS 10.3.1 Perimetr: newest
That is a Maytech VESC without bootloader. Updating the firmware does not work on those without flashing the bootloader yourself first.
How can i get the perimetr to work then??
you get a proper VESC or upload the bootloader. We had this topic numerous times now - search the forum.
Ok thank you Do you think there are people on this forum (in europe) who can do that bootloader for me? I dont have any idea on how to do that Even the forum posts about it just irritate me
I could do that for you in Germany.
For how much?
That would be amazing
30 € ? 
Got all the required stuff right here and used to working with STM32 chips
