Sounds like a use case for touchscreen wall controllers like Shelly ones. Controlling things in your house by unlocking your phone, opening the app, finding the right dashboard, pressing buttons is a poor user experience compared with operating a switch on the wall.

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.

although apparently you can now get fibreglass unistrut. how healthy are your lungs feeling?

too bad you can’t get plastic unistrut. that would be perfect.

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.

its my second throwaway. I threw away the first one.

as someone from the north of England, “scotch” or “ scotch drop” pancakes are very different from crepes and folks here will fight over that

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.

Paying a couple of five or six figure sums to continue advertising on X, versus paying millions to fight a protracted legal battle - I know which option the shareholders of those companies will be pushing for.

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.

+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

Our climate is changing and we need research like this to ensure that we can still grow food productively in regions where weather is causing crops to fail.

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.

You can get that kind of power through a Cat6a or Cat7 ethernet cable but a lower spec cable won’t work. here’s an article that talks about the limitations https://sixtytrend.com/can-cat5e-do-poe/
