I know this is a bit old, but mine just started doing this a day or two ago. It’s flapping between 50 and ~280cm which is the no vehicle distance. I’ve only been running it since August on v1.1.1 without issues. I thought I purchased the USB adapter, but I guess I didn’t. I’m pretty sure it was from an Amazon Fire as well, rated 1A or more.
We have had some recent cooler weather (30-40’s overnight), but are now back up to 78. I’ve fully powered it off/on, updated config and cleared log, but it’s still waffling.
I couldn’t reach the brick itself this morning and will power cycle it later and see if that helps. Any other tips?
Thanks,
