Question about intertechno IT-3500L Set

Good day
It is always difficult to say what the range is, as any object can be an obstacle to the signal. But basically, the range is about 10m if there is no object in the way and both the remote control and the adapter are in the same room.
The adapter is not suitable for the garden, as it is not water-protected. For the garage, I also recommend an adapter with a higher degree of protection. For both applications:
intertechno radio adapter plug
Kind regards
