Questions about smart switches

I have just started playing with some smartbulbs and smartplugs, before I start buying smartswitches for my home (which has a lot of switches) I have a few questions that google couldn't answer clearly.

All rooms in my home have two switches, one at each end of the room, from which I can turn on and off the lights independently.

Is there a way to let google home / alexa / home assistant know that these work like this while both are wired to the bulb, or should I just keep one connected to the wiring and use an automation as the other? I am not even sure I can wire the same way with smartplugs as the originals are 3-way switches.

if I do this, the one that is not wired to the bulb will not work without internet, is that correct?

Can I use a smartswitch and not connect the wires to the lamp and use the button to start an automation? I want to have a double switch that has one button to turn on/off and another that does something else, like changing the color.

Is it possible to connect to cloud using MQTT on a microcontroller that does not have embedded linux?

Hello everybody,

I have a question regarding a project I'm doing for my embedded course. I have a SAMA5D2 Xplained board and a cellular network module that communicates to the microcontroller over UART. I want to connect to Cumulocity Cloud using MQTT.

Every tutorial I find seems to use libraries for embedded linux and I don't want that. I want to write a library for bare-metal implementation. Is there anything that can help me do this (course, existing library, tutorials etc.).

Any help is appreciated!

Getting on the Same Team Financially in Marriage

My wife and I approach recipes differently. Jean has a degree in biochemistry. She’s smart and sees life as a series of precisely calculated moves. To her, recipes are a detailed road map to be carefully followed. If the instructions call for one cup of flour, she’ll measure exactly one cup. She’ll even use a knife to scrape off the excess.

I’m more of a free spirit with recipes. I don’t see them as “a roadmap to follow” as much as “a few things to keep in mind.” I kinda, sorta measure ingredients, but not very carefully.
