How much power do smart sockets consume themselves?

I see a lot of Wi-Fi sockets or plugs etc, but no one ever mentions how much power they consume themselves. They are typically connected to Wi-Fi constantly, waiting for commands. Does this not take power? I know it's probably (hopefully) less than…

Is MQTT protocol appropriate for transmitting sensor readings over BLE?

Assume that there are numerous weak sensors (e.g., Arduino level devices) which rely on BLE as means of communication and that these devices are connected to a more powerful gateway (e.g., Raspberry pi level of devices). I would like to know if MQTT…

Are there any 'minimal' power meter data loggers?

I mean, a device that will just read, persist, and then push the data to a (my) server without having to buy a 3rd party software license. The data being, in this case, electrical generation/consumption. I've been looking at many "smart" meters and…
