there’s a good tutorial to host ollama and a vector database here

Have a look at the LinkedGo wall thermostats. They have Shelly chips inside so rock solid and great compatibility with HA.

maybe just a window/door sensor that uses a magnet to detect closure?

Apollo Automation

The next town over from me has a car/van manufacturing plant. I went there as a teenager to learn about Kaizen, lean, process mapping and critical path analysis.

As an adult I know of a few families who have booked to go to watch robots make cars, see the assembly line and gawk at the massive diagrams on the walls.

Tor operator here.

If you don’t have a second IP for your relay, don’t host at home. You will have CAPTCHAs everywhere, many sites will block you and your ISP will eventually contact you to stop degrading their IP space reputation.

Most website owners don’t discriminate between Tor exits and relays. They subscribe to block-lists that include all known Tor IP addresses. Major online services will make your browsing experience really shitty and once you’re a “known Tor IP” it will take months to remove that reputation.

You can run a Bridge instead, but you will eventually have the same problem.

I use Shelly EMs and EM Pros and they are excellent. My favourite feature is that they work on non-networked firewalled VLANs and don’t need the internet to work.

I’ve got two of the Screek 2A sensors and think they’re good. Mmwave technology isn’t a magic bullet that automatically works every time, like all radio tech there are some limitations.

I use one to turn on a light in a hallway and the other to detect when someone approaches the front door and issue an alert via ntfy.sh. Once in a while it misses some motion, so I’d probably not recommend it if you were building a human life kind of scenario, but they’re fine for me.

More importantly, they’re well supported by HA/ESPHome, open source, inexpensive and compact.

how do you typically notice the filter needs to be changed now? does it:

• draw more power than usual? wattage sensor
• give some alert like a “change filter” light? esp32
• need changing after a certain time/usage amount? power consumption sensor
• need changing every X days? you might just need a calendar alert

of course the mega nerd approach would be to put a particulate sensor in the duct like a PMS7003 that measures PM10 particles like dust, strap on an esp32 and set some alerts using your favourite monitoring tool.

You can always use the Home Assistant API to create your own UI experience. I create small HA touch panels using M5Stack Core2 devices this way.

I would do this with a home-made esphome (like other have suggested). If it has to be a commercial product, you can buy the shelly addon and attach it to any of their Z-wave 1pm products like this one for example.

The addon supports up to four temperature probes and the cables can be many metres long.

I mean, they’re offering a 1 year fixed rate bond and paying 6.71% interest, no wonder they went bust 🤭

Can confirm times are hard. I work at a tech company and every role in engineering gets >100 applications the day it goes live.

My advice - go to events hosted by those companies, get to know the people who work there and find ways to help them. Then get them to refer you for roles.

Twingate is another option if it’s just device to device networking and you trust all the devices that are in your network. It’s free for personal use and peer to peer so no issues with TOS if you’re streaming.

If you’re using OPNsense I recommend you install and enable Avahi to help route discovery traffic, and I would double check multicast is functioning on your wifi.

IIRC with home assistant there are some commands you can run to make it aware of your VLANs… have a look at this

+1 for shelly, a few options that could work.

is multicast DNS enabled and available in that VLAN?

have you set up the network for HA using the

ha network 

commands?

have a look at the Shelly H&T (and the new G3 version). They are cost effective battery or mains powered temperature sensors that include both bluetooth and wifi. They work locally with no hub required but can also report to the cloud where alerting can be configured.

those contracts take years to tender and likely have huge clawback clauses. I doubt that Labour got into power and immediately signed contracts for things like this. More likely it was more expensive to stop it.
