Interference with Husqvarna Automower - GeigerBe - 2014-06-22
Hello,
I have a big problem.
Since my neigbour owns a Husqverna Automower, my station isn't useable anymore. I get Interference all the time!
I checked the internet and found out that the mower uses a magnetic field, inducted by a wire arround the lawn, not to get lost.
Have someone a idea how I can get online again? At the moment a use a frame antenna, would it help to change to a ferrit rod?
Or how I apply filters or something else what my damp this frequencies...
My Station is number 410.
At the moment it's online, but I'll switch it off soon, not to spam the network with a lot of false signals....
And here is my lightingtracker web access:

Greetings

As it is magnetic, maybe you can use an E-Field antenna

There has already been a discussion in our internal forum (search for mower or automower). An automower is one of the worst things that can happen! We have a solution for the RED stations, but even that is only a workaround. As you have a GREEN station, you can try Richos suggestion and/or maybe you can move the station to another place. But don't put too much effort in fixing this. Mowing the lawn of your neighbor by yourself could be another solution
I have the fear that we will have more and more trouble with those stupid robot mowers for lazy gardeners in the upcoming years.
Maybe some ham-radio guys can ask their government agency, why (or whether) such electromagnetic pollution is allowed and what can be done against that. I don't know why those mowers need several 100 impulses per second (!) to recognize their border wire. The same functionality could be easily done with just one (or slightly more) impulses per second. Additionally the border wire should be disabled when the mower is not in use. As far as I know, it's enabled all the time (at least on some of the mower brands).
Robotic lawnmower interference? - mekhall - 2014-07-30
Hello,
I'm looking into the possibility to contribute to the network by, when new PCBs are available, buying a kit.
However, I have a robotic lawnmower and the boundary wire is supposedly sending out a signal that can interfere with for example lightning detectors.
My question is: is there any chance of running a lightning detector successfully if I have a robotic lawnmower? My idea was to put the antenna in the attic of the house (1 floor only), so it would be about 4 meters above the lawn.
I know that it is impossible to give a 100% correct answer, but I accept guesses as well.

It has never work with a Husqvarna automower...

And it is a Husqvarna I own... Hm, I guess I will not be contributing to the blitzortung project after all... That's a pity.

I have a Gardena (made by Husqvarna) automower, Blitzortung works...., but get noise signal every second from mower...

Interesting... The Gardena ones are the same hardware as Husqvarna - only the software is different. Maybe it might work after all then...

You must adjust noise trigger quite high in manual mode for avoid interference, you cannot get weak signals, but it is better than nothing. Range of my detector is now about 1000 km, good enough for me.
