Tasmota API via HTTP using Curl

Tasmota has a huge catalog of commands that can be run via the serial console, MQTT, or HTTP. These commands are great for scripting purposes. The easiest way I've found to send a command is with Curl.

curl http://192.168.1.142/cm?cmnd=POWER+TOGGLE

The API will answer in JSON which is easily digestible with JQ.

curl -s http://192.168.1.142/cm?cmnd=STATUS+8 | jq

Linux: write a network image to an SD card

If you have a fast network connection you can read an ISO directly from the Internet and write to a flash drive, or SD card. Just pipe curl to dd (requires root) and you're done.

curl ftp://mirror.web-ster.com/centos/7.2.1511/isos/x86_64/CentOS-7-x86_64-NetInstall-1511.iso | sudo dd of=/dev/sde
