I recently purchased my wife a Lenovo IdeaPad Duet Chromebook as a replacement for her aging Dell laptop. Since she mainly using her laptop for surfing and light tasks it was a good choice from the reviews I read and at that price point.

In a previous post titled Flashing custom firmware on Gosund SP111 devices I wrote about how I achieved this by connecting the device to a serial connection.

In this post I will explain how I hooked up our normal washing machine to provide some power usage insights, such as sending notifications that include the cycle time and power consumption.

We have a couple Hue Motion Sensors in our apartment to provide some automation for lighting control which work great, albeit a bit expensive.

In our house we have a few older generation Teckin SP22’s running Espurna and newer Gosund SP111 running Tasmota that all publish their energy statistics via MQTT to Home Assistant.
