As mentioned by upon_drumhead (https://news.ycombinator.com/item?id=36841141 https://news.ycombinator.com/item?id=36841141) there are much better devices for this job. I'd recommend anyone looking for this sort of device to check out the devices on this list here (just the Energy Meters section) https://sigrok.org/wiki/Supported_hardware#Energy_meters https://sigrok.org/wiki/Supported_hardware#Energy_meters Sigrok support will ensure you have a well supported open specification device that already has alternative software available in case whatever software is bundled with the device turns out to be substandard or eventually unsupported.
