If anyone has a great, affordable way for peptide analysis, please let me know in the comments!)
I haven’t done this myself (my purchases have always been from trusted sources) but traditionally you get a test from a third party company specializing in it. Janoshik is the one I know of, but there are others.
this doesn’t belong here. there are three (!) main competing iot protocols (ZigBee, matter, zwave) that work with the main open source home automation server (home assistant). many devices are also extremely cheap (five or ten bucks for a ZigBee smart plug).
anyone with a computer and basic it skills can set up home automation these days. if you don’t have that, you can pay a little extra and get a box with home assistant pre installed and ready to go
or, if you think that’s too much of a hassle you can pay even more and get into one of the walled garden ecosystems that use proprietary protocols. Philips, tuya, etc
