Metr Pro CAN [available to order]

Would there be any easy way to just get new cables? Or check the bus? (Should there be continuity through the CANH and CANL lines using stock cables?)

Yes, please check, there should be continuity through the CANH and CANL lines.

Eyy I fixed it! Turns out the high and low pins were swapped on one of the connectors

What’s a good number of satalites to get reliable data?

Why can’t I merge these rides?

Also it only seems to log if the app is open at the start of a ride, if my phone has Bluetooth off and I start skating it doesn’t load anything when I reconnect

Just finished wiring up my Metr on a 5V DC-DC off my main pack inside my battery box with a shielded cable going from my battery box out to the enclosure housing my twin ESC; Did you ever add support for always-on operation?

Do you mean for Metr LTE or?

I have a Metr CAN plus the LTE and GPS modules

Among other things the cell phone app doesn’t exactly show fully paired unless my ESC is turned on.

This is unfortunately not yet done. But it will be!

How is the Wh/mi calculation done with multiple ESC’s and motors? Is that value for one motor or for the whole system?
Main page shows 9.5 Wh/mi and yet the ride record shows 24.7 Wh/km which translates to something like 39.7 Wh/mi; how is there such a disparity?

Here’s the logs; first ride was with both my ESC’s on the same CAN channel (by accident); I power cycled the ESC and force killed the cell app and then reconnected after correcting this; rode a short distance and saw the number disparity for efficiency.

Edit: even weirder, the app notification shows 27 Kw/mi efficiency… none of these numbers line up.

Also, any word on support for Expert mode ESC programming on firmware 6.00+? I just upgraded my ESC’s today and saw I can no longer change settings on the ESC’s.

Update your metr app. It has FW6 support.

Just did; will test again later to see if any of the other issues I reported continue. :slight_smile:

Are you referring to these?

Home screen (middle page), record view screen (second screenshot you showed), and the 3rd - pull down from the top of your phone to show notifications. The Metr entry shows a difference there too. This is specifically with two ESC’s, twin motors, (and in case it matters, I’m running 8:44 gear ratio with 225mm wheels)

Those are different kinds of Wh displays

This shows your current/live consumption

this is the average from the ride/record

this i believe is also a live feed from your current consumption, just with a different refreshrate

correct me if i’m wrong @rpasichnyk

Last question - What would it take to allow for the records to display in Kw/mi instead of Kw/km for the record screen depending on distance unit setting?


Temperature C/F can be changed individually in case you want Miles and C or Km and Fahrenheit.

Oh cool! Wondered what those buttons did but didn’t realize it was for display. Nice!
