The Definitive Guide to Metr App / Metr Pro

I have the garmin Venu Sq and wanted to get the watch app, but it looks like the Sq isn’t supported :confused: Any chance you might be able to add that watch easily?

UPDATE: I fixed the issue by changing the CAN ID on the BMS from the default of 10 to 11.

I wanted to try connecting my Ennoid BMS to Metr, it’s having some issues :grimacing: this is what the RT screen looks like

When I go to the Expert tab for the Ennoid BMS it says that firmware 5.4 isn’t supported. I saw in the X-LITE thread that other users were able to get it to work…

Can you please open Metr → Settings → Show logs → select day when you recorded this video, and send to support@metr.at ?

Thanks for the log files! Metr Pro still uses DieBieMS protocol and not VESC BMS protocol. Can you please check this post and change to the old protocol on BMS?

I injured my wrist a few days ago so it’ll be a little while before I can open it back up to try changing the protocol. But I was wondering, do you have plans to implement the VESC BMS protocol into Metr? It would be really excellent to be able to track the BMS through Metr while preserving the connection to VESC.

Another question, I was excited to get it set up in the first place because I wanted to see how the Metr would prioritize conflicting info from the VESC. My little FOCer isn’t calibrated well and reads about 1.1V lower than it should, so when my 19s battery is full, it only reads 78.7V. It throws off the SoC and range estimates a lot. It would be really amazing if the Metr could only show SoC and voltage data from the BMS which has coulomb counting and configurable voltage factors.

I changed the “load status protocol” from VESC to Ennoid/DieBieMS and it’s still having the same issue. I rebooted both the VESC and BMS and re seated the cables a few times.

I’m sure there’s something I could have done wrong with the setup… The same thing has happened with two different Ennoid BMSs and two different Metr modules (upgraded to the SD card version). But the BMS was working normally with VESC tool when it was plugged in to CAN.


Phone is not on power saving.
Same setup.

Randomly does not show gos or erpm speed

Any suggestions? Running og metr pro. Samsung note 20.
Jan 1, 2023 - metr.at | 0getq. Working speed
Jan 2, 2023 - metr.at | R1Ud2. No speed working.

What esc? Some newer hv escs have been showing intermittent uart stuff

My metr can isn’t seeing the second ESC, troubleshooting suggestions?

The second ESC is definitely connected, motors still run

Are your VESC IDs different?

Yeah, rewrote them as 0 and 1 a while back

After reconnecting it had both again but the log shows only the one motor

Do you have “split logs” enabled?

Where is that?

I swear it was a setting somewhere but now I just can’t seem to find it

@rpasichnyk Got a feature request here to toss in your backlog:

It’d be rather cool to have metr detect that the phone is nearby enough and, if not, go into some kind of slow-halt-resist mode. Like, if the PEV is moving, just remove motor power. If/when the bike is at zero speed, short the motor phases so the PEV is super hard to roll. (Maybe metr can’t do that on it’s own, but even just the “no motor” would be awesome.) A bluetooth tether, in effect.

Would anybody happen to know of an American source for a 4pin JST PH to GH connector? The one used to connect the metr CAN to a vesc

If you have a fall and smash your phone
If your phone battery dies

…you can’t get home?

What, you don’t have two phones?

Jokes aside, depending on how it’s implemented, disconnecting the metr could potentially prevent the hold/resist behavior.

But also – what if you crash and your throttle shatters? Or your battery pops a weld? Or you simply (and far more likely) blow a tire and didn’t bring a spare? Snapped a belt? There’s tons of failures that’ll sink a ride and have you Uber’ing a truck home. That doesn’t make this a bad idea, sheesh.
