Yarbo went out again today at 9.30AM, in drizzling rain. It ran over an big tree branch that fell down over night. It then stopped it’s job and went back to the charging station, we’re it went offline, at 4pm I found it there with the big log still stuck under the mower, which it dragged down the whole hill and ripped up the lawn. Still offline and not reachable until I could get a Bluetooth connection in the end. Luckily the mowing disks did not break. After reboot everything seems to be fine. I couldn’t get any moisture values today, because of the unit going offline.
I don’t get how it could not see this big thing, when it sees non existing things lying around everywhere (and colors the whole map with red dots).
Rain alerts kept calling my Yarbo in this evening, even though the sky is clear. After blowing out the sensor with air, a shutdown, battery disconnect, restart, and phone restart, it still wouldn’t mow because of “rain”. So I selected “mow in the rain” and restarted my plan. Now it’s mowing. Rain sensor reading = 0 (after selection). Also the battery charge level is stuck at 100%. I hope this can be fixed because I would like to use the rain sensor and have an accurate battery reading.
Thank you for sharing your experience. Could you please send us some videos showing the blue LED flashing phenomenon? This will help us forward the information to our support team for further investigation. Since videos can’t be uploaded directly to the forum, perhaps you could upload them to another platform and share the link here. We appreciate your help!
Do you have a mower house or did you actually modify a dog house for it to park in? I’m trying to find some sort of housing to cover the bulk of the unit when it’s parked.
End then it keeps doing that silly thing where it takes 40 seconds of wiggling around to go I a completely different direction in the end. https://photos.app.goo.gl/k5hKfEq4R8Fn6S2Z6
@tano The problem the sensor always reads low if it’s slightly dirty - mine is <200 despite raining for two days, and the “don’t mow!” threshold is 1000. I just cleaned the sensor a few days ago – it’s already dirty enough.
Even if you clean the sensor and get 2000 from it (which I did), it will dry out FAR before the grass. So, in practical terms, the sensor really isn’t viable, at least for me. Instead I use my Mowing Operation Initiation Slipper Test (MOIST) – I walk in the grass and look down at my footwear.
I’ll be using the scheduler and turning everything OFF/ON manually. No biggie. They really need to create or integrate with a grass moisture sensor (not soil, grass, which you can probably build using an Arduino but need an API to talk with the rover (may get API access someday, they’ve talked about it, but it’s not high priority AFAIK)).
@bryan.wheeler I tested it a few days ago. My rover went out in the rain to run a Work Plan I started manually at 995 or something. It didn’t if the sensor was >1000.
Easy enough to test.
Clean the sensor thoroughly. I used Simple Green and a paper towel.
Rinse, leave water on it.
Check the sensor value. Ensure it is >1000.
Start a Work Plan. It shouldn’t go.
Wait until the sensor is <1000. Start a Work Plan. And away it goes. Well, it did for me.
We’re sorry for the confusion and apologize for the earlier miscommunication. After confirming with our product team, the trigger value for the rain sensor is currently set at 1000. We also understand there have been some issues related to the rain sensor, and we are actively considering ways to optimize its performance. We truly appreciate your continued support.
