This looks very promising for firewall/ router/ wireless backup /hub combo device. Has anyone seen the LoRa and 5G LTE modules that work in this device? Strangely, the site mentions, but does not seem to list these modules.
You are right, hard to find ready-made low wattage 120V power meters. Very hard to find meters for measuring even ~12 watt load with even 10% or better accuracy (1.2 watt). I think most folks just use multimeter and estimate real power.
