DIY out-of-band management: remote power button
Great project but a little too much for the ones of us with only software development skills.I use smart plugs over Wi-Fi to do that. Shelly Plug S have a small physical button, a web app, a HTTP URL to call to switch the plug on or off. They also have a lot of features that I don't need. Among them MQTT and Alexa/Google integrations. A few bash scripts with curl and I can do everything I need. The price is reasonable and they saved me a lot of time.
