> I just want an IoT plug so I can switch things off and on. It should expose a tcp port and allow me to send packets to it via wifi with some level of authentication. I don't want any cloud shit with it. Just a simple (okay, it's not actually that simple) device that connects to wifi and lets me throw packets at it to control it.
Shelly devices offer a firmware that can be controlled trough a REST API locally. Unfortunately it's still proprietary and not open, but it doesn't require a cloud connection.
Otherwise you can buy a device and replace the firmware, there are number of open alternatives, such as ESP Home, Tasmota, etc.
Or... you can build it yourself. Building a smart plug is an easy task, if you have some practice on electrics. You will likely build a better product in terms of safety and capabilities that one you can buy.
