I'm looking to replace a "dumb" thermostat in my house. My biggest problem is, the Family (well MIL) will be the primary user of said thermostat. Were it up to me, i'd just duplicate the setup I have in my detached garage (ESP32 and 4channel relay board, with remote temp sensors).
My second biggest problem is many of the smart thermostats requiring internet access and control only being available through their External API. Ideally I'd like something that is 100% local control, with opt in for any remote data.

What setups do you have? do you like it? is it "normal" person friendly?

I've recently decided to up my security, but I don't want it to be an annoyance for the family to use. I also have an aversion to web hosted things, so I'd like something that is locally hosted/controlled, without a "Setup app"

I'm open to deadbolt and regular latch smart locks.

What options are out there? what do you use? do you like it?

I've recently been trying to degoogle myself, and in doing so I'm going to need another email. I tried ProtonMail, but apparently only business accounts can use SMTP, even though their features claim SMTP access. I'm plenty fine paying for the service, but going from the $6/month to $12/month just to get notification emails from my server doesn't seem worth it to me. I've not looked into what all else comes with Proton's Business features, but i'm not really running a business or trying to start one up.

What do you use? do you like it? How's the cost/features?

I've recently decided to try and degoogle my life, or at least lessgoogle it. One app I use regularly is GoogleVoice. It works really well to keep my work and personal numbers separated. Also works reasonably well to keep my personal number clean from spam. What is out there that provides similar functionality?

I'll start out saying, i'm not very good with this stuff.... I have an Ender 5+.
I had it setup with octoprint and klipper from a guide I found a couple years ago, and it worked OK for me to get klipper installed, working on octoprint, and pressure advance tuned ok ish.

Recently my SD Card became corrupt, and like an idiot I didn't have anything backed up.

So I'm trying to setup the system again from less than scratch and it's kicking my ass.

I've decided i'd like to try Mainsail, as it's interface looks interesting (no other reason) But I can't for the life of me get it working.

EVERY guide I try and follow seems to fail on the connect between klipper and the printer.

I can flash the klipper firmware successfully, and have updated the port ID in the printer.cfg file, but it always comes back to klipper not being able to see/access the port.

Any help would be appreciated here.
