I am having extremely poor communication range with Nexa WTE-2 433Mhz wireless wall switch. It is somewhere less than meter only if both devices are it in direct view.
Does anyone have experience with Nexa WTE-2 or similar 433Mhz device?
Since I noticed several posts in the forum about bad communication for 433Mhz devices. Would it be possible to boost range by modding with external antenna?
