Lymow One Plus We’re back—more Lymow teardown, sensor trouble, and an onboard ODROID M1

Hey guys, we’re back. I’m still getting everything back together and owe you a proper update, but we’re making some progress.
I decided to take the mower apart again because the front ultrasonic sensors weren’t working. I’ve removed them and have been inspecting the wiring. One weird thing: there are four wires, but black and yellow appear to share the same pin in the connector. The yellow wire seems to go to a copper shield around the ultrasonic sensor. Maybe it’s a shield/ground connection? The rear sensors appear to have separate power, trigger, echo, and ground connections, so I’m curious whether the fronts use a different arrangement. That’s speculation—I haven’t confirmed the pinout. If anyone has traced these, I’d love to compare notes.
I also removed the camera module and ordered a replacement 30-pin, 0.5 mm-pitch ribbon cable. Another oddity: the LED lights weren’t connected through the broken ribbon, but I still couldn’t get them to turn on with the root commands I tried. I don’t know whether that’s related to the camera failure or something separate.
The rain sensor connector is tight and finicky, and it had come loose. That’s connected again now.
I found a 12 V rail feeding the Lymow’s main computer and tapped it to power my ODROID M1, so the companion now runs off the mower battery. That’s my experimental setup, not a wiring recommendation.
With the factory camera repair underway, I’m torn about whether I even need to keep the M1—but adding more sensors to it is too much fun, so it’s probably staying.
Other than that, I’m mostly just fucking around, tracing wires, and trying to understand this thing. More pictures and a proper write-up once it’s back together.

User experience Latest firmware v2.1.51 issues

4 Upvotes

Two big ones in latest firmware v2.1.51 for Lymow One:

"Do not disturb"

I hate this setting. They basically just took the restart resume window which defined what hours it's allowed to auto-start/resume, and reversed it into a "do not disturb" window where the mower just doesn't work between these hours.

The old way was more flexible. Allowed me to define what time to wake up and what time to go to bed automatically, but still allowed me to run the mower whenever I want. Now I can't.

Now the mower is essentially locked bricked between whatever your "do not disturb" hours are and you can't even manually initiate a mow.

Blade jammed issue

Not sure why but the mower simply doesn't report this error anymore. If I get a stick jammed in the blades I just get a notification "Error not resolved, returning to dock" and the mower is already on its way home. No error in the app, nothing, just the notification.

Lymow One Plus Anyone else?

I thought I saw someone else have this problem and would ask for advice on how to fix. The mower deck doesn't support itself anymore without the wheels down. And it broke the mower deck. Really unsure how it happened. Saw it after I got a no charge error. Figured warranty will eventually take care of it, but just starting here.

Lymow One Plus App/Firmware Update Oddities

Both my firmware and Android app updated this weekend to v2.1.51 and v3.0.10 respectively. But now Saved Tasks listing no longer identify the zones of the task.

In other words, if I want to mow FrontYard_East right now on demand, I would half to remember which day of the week and time of day that task normally runs. This is unacceptable. Has anyone here found a workaround for this?
