I created an HA app that helps identify and track vehicles using their TPMS sensor broadcasts. Curious whether anyone else has played around with TPMS signals or done something similar. I’d love any feedback from others on whether this is useful.

TireSignal - GitHub

Basically, it listens for tire pressure sensor data via the rtl_433-hass-addon app, groups repeated signals, and helps identify which sensors likely belong to which vehicle. The goal is to make it easier to tell “that’s my car,” “that’s my trailer,” “that’s the neighbor’s car that always shows up,” etc., instead of staring at a bunch of random sensor IDs.

I swear, I'm done with Wi,Fi devices.

Every single one is "local", until it randomly goes offline for absolutely no reason. Then you spend hours checking DHCP, static IPs, mDNS, firmware updates, router settings, rebooting everything, and somehow it's magically fixed... until next week.

The funny part? My Zigbee devices (not battery powered) just sit there quietly doing their job. No drama. No random disconnects. No "Device unavailable". No Wi,Fi congestion. They just work.

At this point I'm replacing every Wi,Fi device with Zigbee as it dies.

The hell with Wi,Fi. Zigbee is faster, more reliable, and doesn't make me question my life choices at 2 AM.

I freaking love Zigbee. ❤️

I've been thinking about installing a video doorbell for a while, mostly to keep an eye on deliveries and see who's at the door when I'm not home. There are so many options now that I'm finding it hard to separate genuinely good products from ones that just have great marketing.

The biggest things I care about are reliable motion detection, clear video during both the day and at night, quick notifications, and something that doesn't constantly alert me because a leaf blew across the driveway.

I'm also curious whether a subscription is actually worth paying for or if the free features are enough for most people.

If you've had a doorbell camera for a while, which one did you end up buying? Would you choose the same one again, or is there something you wish you'd known before spending the money?

Does any sort of redundancy exist for home assistant? if the system goes down another can pick up the work load?

I know people use proxmox clusters but for those that don't have this are there any other solutions?

I am trying to make my smart home work in such a way that lights etc work if the system is down but there are exceptions to this such as mmwave sensors won't work for lighting

same with zigbee and thread coordinator failures.... if they fail the system goes down... any solution or is it just keep spares?

Sorry if this all seems daft but it's things I've been wondering for a while!

Hi all

I use the HA integration for WV.

But it has stopped working.

VW is blocking.

How can can we tell them that is is just stupipd?

My two cats — Susi (British Shorthair) and Loki (Maine Coon) — refuse to drink from a bowl like normal cats. They want fresh running water from the bathroom faucet. So for years my "solution" was to open the tap just a tiny bit, so a thin stream runs for them. The actual problem: **me.** I constantly forgot to close it again. More than once the tap ran all night — or the whole day while I was at work. That's a lot of wasted water for two spoiled cats.

First attempt was a PIR motion sensor + Zigbee solenoid valve. Worked great, except a PIR can't tell a cat from a human, so the faucet also opened every time I walked into the bathroom. Not ideal.

The fix: actual object detection.

Camera: Freenove ESP32-S3 WROOM CAM (16 MB flash / 8 MB PSRAM) with an OV5640, streaming MJPEG over RTSP at 1280x720, ~10 fps. No H.264 on the S3, but for a single camera Frigate handles MJPEG just fine.

Detection: Frigate + Coral USB TPU on my home server, detect at 5 fps. A zone drawn exactly on the sink, so a cat lounging on the toilet lid next to it doesn't count.

Action: Home Assistant listens for cat in the sink zone → opens a smart valve on the water line. When the cat leaves there's a 45 s run-on timer, plus a hard 3-minute safety cutoff in case Frigate decides a towel is a cat at 3 am. And an input_boolean master switch so the automation doesn't water *me* down while I brush my teeth.

Bonus: the line runs through a countertop water filter, so the cats re drinking filtered water. Yes, they drink better water than I do.

(The ESP32 is still a bare board on the wall — the case is in the 3D printer queue, as is tradition.)

Funniest bug: Loki the Maine Coon is apparently too big to be a cat. The COCO model occasionally classifies him as dog (screenshot attached — the model is *confident* about it, too). Since there's no dog in this household, I just added dog to the tracked objects. Problem solved, dignity of the cat questionable.

Happy to share the Frigate config, the HA automations (4 of them: open, run-on timer, close, safety cutoff) and the PlatformIO firmware if anyone's interested.

Been tinkering with HA for a while and kept running into the same problem: most beginner guides either skip important steps or assume Linux knowledge. So I put together a full series covering everything from zero.

Here's what's in each part:

1. What is Home Assistant and why run it locally? – cloud vs local explained, what you can control: https://youtu.be/zSZIDPAJM7o
2. Installing HA on an old PC – full HAOS install on any x86 machine, free, takes about 20 minutes: https://youtu.be/ON_o-7OnsvY
3. First setup: network, users and your first dashboard – getting from a blank install to something actually usable: https://youtu.be/muOjMoSu8gM
4. Top 10 free integrations every beginner should add – weather, Google Calendar, mobile app, energy monitoring and more: https://youtu.be/MwfbYNkBtrA
5. Your first 5 automations – time-based, presence detection, sunrise/sunset, all done with the visual editor (no YAML required): https://youtu.be/wvGBYJbT0SE
6. Connecting smart plugs and lights without cloud – Tasmota, ESPHome, Zigbee2MQTT and why keeping it local matters: https://youtu.be/QQii9H5IsK8
7. Building a good-looking dashboard from scratch – Mushroom cards, custom layouts, dark mode: https://youtu.be/qUOar06yXLI

Everything is free on YouTube. Happy to answer questions if anything is unclear — this is the kind of series I wish had existed when I started.

I’m trying to sleep early but since I started using HA I’m too excited and spending too much time on it fixing things I couldn’t do on HomeKit! 🤣🤣🤣

It’s 3:20am and I’m still thinking about automations hahah.

I built a custom 4-layer PCB with SCD41, SGP41, SHT40 and BMP280, running ESPHome. Sensor fusion, air quality score, configurable thresholds, three isolated power rails. Making it public in case anyone wants to build one.

https://github.com/roepkefeller/air-quality-sensor

Usually I don't show my projects online (IP/industry stuff, the kind of hardware I am developing is pretty closed source..), so I'm very interested in some thoughts! If anyone builds this board please let me know haha. I'm also happy to answer some questions!
