Some news on the ANFR procedure. Obviously around ten cases identified in France and Switzerland. And to their knowledge, only 1 case where Mammotion managed to resolve the problem by updating. Mammotion tells me there's nothing they can do. I asked if they could do an exchange with a model that complies with French regulations! I'm waiting for their response (the app's after-sales service function is really not great and they're not very conversational!)

V zgornji temi je omenjena frekvenca 868MHz.

This shows the utilization of the 868 MHz band with RTK off(left) and on (right)
With RTK on, the "Carrier Sense" value increases. This value measure the utilization of the 868Mhz band. I.e. the RTK station is using way more than its legally allowed 1%!

Hello, last week I received a visit from the national frequency agency (ANFR). Apparently the RTK antenna of my LUBA 2 robot lawn mower jams radio frequencies and is the cause of disturbances several kilometers away. They acted on a report from companies and then took lots of technical measures to get to my house.
According to their report received a few days later, roughly:
"the disturbance is due to non-compliance with the technical criteria of the frequency band 868 – 868.6 MHz with a frequency occupancy rate of around 30%.
[...]
In the present case, this concerns the use of radio equipment outside the technical conditions for the use of radio frequencies by short-range devices set by decision no. 2023-1412 of July 6 and which by elsewhere disrupts a network."
Basically, MAMMOTION sells us equipment that is not even approved!!!
So I had to unplug the antenna from the robotic lawnmower and can no longer use it. I just have to hope that MAMMOTION finds a solution to this problem. A bit light for a mower sold at this price!
Basically, either unplug your robotic lawnmower or prepare to receive a visit from the ANFR.
MAMMOTION, a comment?
