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.

Calling it now - it will be written in such a way that Musk’s motley crew will be required to maintain it or update proprietary closed source components at extreme cost forever - practically guaranteeing he will always have full access to the data and be able to charge what he likes for any changes whoever takes power after Trump is gone.

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.

Yes! another vote for Wacky Wheels

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.

so true. I too long for an alternative car that features a fart button and a voice changing megaphone and who the fuck knows what else.

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.

jupyter notebooks, or if you’re super trendy give zerve.ai a try

In the first mission of Battlezone, it’s possible to travel out of the map and find a 1960s lunar lander that you can enter and pilot. It’s equipped with a one of a kind super weapon that plays trance music as you fire it.

Unfortunately it’s only available in the first mission and you can’t take it with you to subsequent missions.

definitely run two cables for each point. nothing beats having a cable be broken somewhere in the walls with no way to repair it.
