HS1XXPlug
TP-Link has a set of interesting WiFi smart plugs -- the HS100 which provides remote access and control for a power plug, and HS110 which is essentially HS100 but with energy monitoring.
Both smart plugs are only accessible through the Kasa app and there is no official documentation on how to programmatically control either of them. However, they have been reverse engineered and several of these attempts have been documented:

hs1xxplug is a Go library for accessing these smart plugs, based on the information available above. I have tested them out with a HS110 only and it works perfectly fine. An example of how to use this library is:
package main
import (
"fmt"
"github.com/sausheong/hs1xxplug"
)
func main() {
plug := hs1xxplug.Hs1xxPlug{IPAddress: "192.168.0.196"}
results, err := plug.MeterInfo()
if err != nil {
fmt.Println("err:", err)
}
fmt.Println(results)
}The results printed (after cleaning up):
{
"emeter": {
"get_realtime": {
"current": 0.015135,
"voltage": 296.213416,
"power": 1.193017,
"total": 0.061,
"err_code": 0
},
"get_vgain_igain": {
"vgain": 16566,
"igain": 13042,
"err_code": 0
}
}
}Functions include:
- TurnOn() -- turning on the power on the plug
- TurnOff() -- turning off the power on the plug
- SystemInfo() -- getting information on the plug
- MeterInfo() -- metering info on the plug, including the current, voltage, power and the total power consumption till date, as well as the vgain and igain
- DailyStats(month, year) -- energy consumed per day for the given month and year
