I'm just curious if anyone has found a set of valve stem cap TPMS sensors (based on the VC601 chip) that they've successfully logged with Harry's LapTimer?
The only set I can find that specifically mention VC601 are these, which are fairly expensive for a Chinese generic TPMS.

I'm hoping someone can point me towards a known working set.

Just because we had edition specific features in another thread: TPMS is a GrandPrix feature too.

I'm not clear on what you are trying to communicate above, Harry.
I do have the GrandPrix edition of the app.
Here's a set of external Bluetooth TPMS sensors at a very reasonable price, but I don't know if Harry's LapTimer GrandPrix would recognize them as there is no mention of which chip they use.

Just try it? VC601 based TPMS sensors will broadcast data at very low update rates. So wait up to a few minutes to check whether data is coming in.

I currently don't own any. That image was from AliExpress.
My hope was to find someone within the community who could direct me to a proven working set.
But since the second link above is relatively inexpensive, I'll order and give it a try.
