70cm x 70cm is even bigger than Eve Energy plugs, and they are already too bug. When Aeotec )zwave) and Tuya (Zigbee and WiFi) can do plugs that can sit side by side in a double power outlet, with energy monitoring, and another reputable home automation site has smaller Zigbee with power monitoring available, these are not acceptable. I bought one as a test and will never buy another. There are smaller, fully certified and compliant, devices available that do the same job. Home Automation is meant to make life easier, not block up additional power outlets
