Can anyone recommend an aftermarket TPMS system they have gotten to work with RD?

Bump, nobody using aftermarket TPMS?

These should work, but i didn’t get them yet, quite pricey.

Thanks for reply, Yikes you’re not kidding! may just have to get a set of usb and see if i can reverse engineer the data, only issue i see is the addressing of each.

Wish you good luck, i think it might be time consuming to reverse engineer them.

Addressing of each should not be an issue you can just power up one at a time.

Those AIM ones look good, but i’m not sure what the battery life would be like on a road car, I’m in discussion with them on it.

I have done some research and have been in touch with the manufacturer of the can-bus TPMS system which is Tiremagic which provided me the can-bus protocol specs, it does look a little beyond me at this early stage of my learning curve. Maybe RD wants to implement it? My thought was to use a can-bus to usb adapter???
If anyone interested, maybe there is an upload section here? or I guess I could make a dropbox link. Any way much more obtainable cost through Alibaba @ $55usd each.

My personal preference would be for internal sensors.

They come either way, also RS232 is available

That’s a good find on ali, you would need the recevier box also as that will generate the can frames.

As you have the spec you should be able to bring them into RD via XML file once the receiver is on the canbus network.

Another option

I’m seeing if i can get the can info for the TMS-4 and will let you know.

12

I do believe Tiremagic is the manufacturer of that unit, I will post a dropbox link later tonight.

13

Here is the protocol

Thanks for that info :slight_smile:

Will see if Haltech revert also, for £150 this looks like a decent option to get TPMS data into RD.

I’m using I2M TPMS Can Bus version.

Transmits Battery status, RSSI, Pressure and Temperature (inside tire) to Can Bus.
Bit pricy however…

second page is english :laughing:

I’ve got the Haltech unit now.

Going to have a go at getting the data into RD with RDCAN, open to help from the devs :slight_smile:))))

17

I had gotten the unit I linked to, and Jani helped out with an xml. My first attempt at testing didn’t work out as I got no response using a usb to can adapter and just haven’t had the time to mess with it further. I added the xml to dropbox folder.

18

Thanks for sharing that, I’m away for a week or so, but will look into after.

19

I’ve got the TMS-4 installed now and using a slighly modified version of the xml posted in this thread.

I also notice that tiremagic is present in the connections menu in RD now.

Anyway, I’m only getting a pressure reading for the Front Left tyre, the other 3 are all at zero.

XML below.

Yes, I accidently left it there for the public version.

Could you go into CAN Monitor and save the stream from TPMS system for a few seconds? Then send the log file to me.
