I have found my people!

solidgrue, 1 year ago to homeassistant in what esphome presence detection sensor?

Interference and crosstalk: Both 24GHz and 60FHz mods are tolerant of other emitters in their field of view, so you could pair two of them in the outside corner of your ell, looking towards the ends and a third at the long end of the ell looking back towards the corner and they ought not to interfere. Another possible configuration would be three ceiling mounted emitters looking down, overlapping the fields of view for full coverage of the floor area. A 60° field of view at 2.8m gives you roughly a 5m radius of detection on the floor.

Seeing through walls: “Thin walls” attenuate the signal, but allow enough penetration to detect people through cover. The radar can penetrate thin plastic housings, plexiglass, cloth, drywall, wood paneling, and thin plaster & lath. It cannot penetrate glass, stone, or metal. Same goes for floors. My radar module will detect people in the unfinished room below my home office through the hardwood floor if I angle it down far enough.

Fast detection: I found that while the radar was responsive even to small movement nearly instantly, it takes up to 2 or 3 seconds to acquire and classify a target as a person. Once t locks on, it pretty reliably tracks the person for as long as they are in view. In practice, a person walking into the edge of the field of view at a normal walking pace could cover half the field before they are detected as present. It “feels” a bit slow compared to PIR detection which is sub-second in most cases, but generates a lot of false positives. The technique I am refining is to position the the radar to detect a person entering a room by angling the radar field of view to “lead lead target” and use the PIR to determine the target has moved into a zone where I want action to take place. In essence, I want the lights to trip on when the radar detects human presence AND the PIR sees a hot blob. Then I kick on the light and wait for the human presence detection to go back to unoccupied for 5 minutes before turning off the light. I might also experiment to see if ultrasonic detection is any more reliable than IR, since it wouldn’t be fooled by warm/cold draughts, or by sudden changes in light as from dappled shade or clouds & sun. My concern is I have pets and wouldn’t want to stress them with sound I can’t hear, but maybe they can. Need to research it more.

Its been fun playing with this stuff, but I might note that at this point you can just buy an open platform (as in open source) esphome/HA compatible multisensor presence detector made by the guy who does the Everything Smart Home channel on YouTube. He posted a couple videos talking about it (links below). For me, this is just messing around with something I always wanted to play with, but I’ll probably just buy a kit when I want to hang something functional on a ceiling or wall.

Definitely check out the videos I linked. They’re excellent for helping to understand the pros and cons of this tech in real-world smart home applications.

I pay for Hulu and Prime (for the shipping), and get Netflix & Apple TV thru my T-Mobile subscription.

edit: oh, derp. I also have YouTube premium because I paid up for the Google Play Music family plan back in the day, and then it converted to YouTube Music + Premium. Later, I upped my subscription to Google One for the extra storage and phone support and get some okay, ad-free free content on the 'Tubes

I pulled up short of “genocide,” but someone else alread pointed out it is Hershey’s in that pot.

Douglas Adams would approve

solidgrue, 1 year ago to RedditMigration in This is the Reddit app. They are making it really easy to want to migrate

That’s atrocious, plug in y’damn phone!

Also, wtf is with that app? So cluttered.

Yes understood. See edts up thread

solidgrue, 1 year ago to selfhosted in Running immich, HA and Frigate on a RPi4 with Coral or on a HP Prodesk 700 g4 (Intel 8th gen)

I think the i5 is Ivy Bridge, but I couldn’t tell you what gen that is. My main use of HA aside from the automation is Frigate, which apparently needs the hardware AVX flags. This chip supports AVX512, where my older AMD did not, so that’s why I went with it. Its an i5-3470T, if that helps.

For an older SFF unit, it’s a beast for HA.

solidgrue, 1 year ago to selfhosted in Running immich, HA and Frigate on a RPi4 with Coral or on a HP Prodesk 700 g4 (Intel 8th gen)

I’ve got HA with Frigate + USB Coral w/4 cams, FlightRadar24 receiver/feeder, ESPHome, NodeRed, InfluxDB, Mosquitto, and Zwave-JS on a refurbished Lenovo ThinkCenter M92p Tiny, rigged with an i5 3.6GHz, 8GB RAM and 500GB spindle drive. It’s almost overkill.

Frigate monitors 2 RTSP and 2 MJPEG cams (sometimes up to 3 RTSP and 5 MJPEG, depending of if I’m away for the weekend) with hardware video conversion. FR24 monitors a USB SDR dongle tracking several hundred aircraft per hour. I live under one.of the main approaches to a major US hub.

Processor sits at 10% or less most of the time, and really only spikes when I compile new binaries for the ESP32 widgets I have around the house. It uses virtually none of the available disk. It’s an awesome platform for HA for the price.

If that’s true then I’m not afraid to start lobbing terms like “crimes against humanity” around

How deep does this rabbit hole.go???

solidgrue, 1 year ago to linux in What's your experience with a touchscreen laptop on your distro?

I’ve had a couple touchscreen portables that run Linux. I virtually NEVER use the touchscreen on the traditional notebook style portables, which are an Asus Zenbook from the mid-2010s and a Dell Latitude 7390 from 2017 or so. Both run Debian/XFCE. The desktop environment isn’t really designed for touch interaction, and the screens have pretty low resolution and terrible multitouch support. It works.for the odd button press, or to advance slides during presentations. It’s just not a great experience. Plus, both of those screens smudge like the Devil, and just collect fingerprints & dust.

The third portable is a Lenovo Carbon X1 slate, one of the generations from late 2019. It has a Wacom 3000x3000 touch display built in, and a multifunctional stylus. I run Mint Debian Edition with Cinnamon on that one. Its on Mint 18 or 19, so take the next bit as how it was a couple years ago: the touchscreen experience in Cinnamon is functional but a little.clunky. Touch interaction is responsive, accurate and smooth. Writing with the stylus takes some getting used to, but taking handwritten notes and diagrams in Xjournal or an app called Write was okay. I never got the hang of calling up the on-screen keyboard in fewer than a couple.of taps, but once it was up it worked fine. Its terrible for coding or commandline interactions because the special character layouts were more iThing-like.than Android but it did work, even if slowly.

One thing I did struggle with was screen rotation. I had to download and tweak a script that called some xrdb or xrandr commands when the orientation changed. Kludgy, but it did work and it got the job done.

I imagine newer versins of Cinnamon have improved on all this in the last few years. In fact, I was going to make a project this week of reinstalling that system on the latest LMDE to see if I couldn’t make better use of it now that we’re back in the office a few days a week. I was getting the hang of the digital notepad, and now I kind of miss it.

(Why reinstall? Dumb decisions on my.part when sizing the slices I used for boot and root. Gotta blow it all away to make it right.)

Happy to answer questions if I can.

solidgrue, 1 year ago to homeassistant in Do I need a separate HA Cloud subscription for the cabin?

You might be able to do something with local Zigbee2mqtt or Zwave2mqtt proxies at the cabin, and tie those areas back into the main instance over Wirguard or Zerotier, but you’d need a pretty reliable internet service at the cabin to do so.

I don’t use those proxies myself since ai just use the one local hub, bit it should be possible. Maybe someone with more experience with those proxies could chime in?

solidgrue, 1 year ago to lemmyshitpost in have you been doing crime?

I need this on a pressed tin sign. Like 12x16" or 18x24".

solidgrue, 1 year ago to asklemmy in Aside from blocking instances, what other controls do admins have to keep unwanted content off their instances?

Seems to me if you're good with Postgres you can do whatever you want.

... Oh, this isn't a helpful answer.
