Everspring SP103 range of action

Hi,

I’m using an SP103 with a VeraPlus box, the SP103 works well (motion is detected) when it is approximatively at 1m from the controller but when I increase the distance at ~2m the controller does not receive message anymore. Any idea?

The spec indicates more than 15m so very disapointed at the moment.

Thanks

Does anyone else has the same issue?
