Hi is there any signal jammers available to block smart meters which uses wide area network to stop them communicating?
Its Landis Gyr e470 type 5424 it also has Zigbee MAC symbol
The most popular in the smart home industry are four wireless technologies, namely wifi, zigbee, z-wave, and Bluetooth. Among them, wifi technology and zigbee are the two technologies that are most worthy of competition.
It’s not wired there are two lights one WAN and HAN so meter must be using somekind of WiFi 4g or 5g to communicate, Is wide area network same as 4g 5g?
ZigBee uses the flexible operating band 2.4 GHz, and both 868 MHz and 915 MHz are used as license-free bands.
ZigBee is an internationally accepted wireless communication technology, which can access up to more than 65,000 ports per network port, suitable for home, industry, agriculture and many other areas of use, while Bluetooth and Wi-Fi network end can only access 10 ports, obviously can not adapt to household needs.
They shut my electricity supply remotely without visiting my shop.
Do not want them to maliciously control your meter through ZigBee, you need to block these three signals: 2.4 GHz, 868 MHz and 915 MHz!
This 6-antenna jammer is recommended:
