It is not easy to help from a distance. The only option is to install existing or additional repeaters closer to the sensor. However, there is still no guarantee that it will work. At your own risk, you can also add an external antenna to an Aeotec repeater, which also increases the range: > [@Aeotec zwave repeater antenna mod](https://community.homey.app/t/aeotec-zwave-repeater-antenna-mod/5817): > > You need: 868 Mhz antenna 8dbi SMA pigtail calm hands Careful, you work with 230 volts! Range is 30% better. No comment: Be careful, high voltage! Merry christmas.
