Check out this device. I have several and they work well. Zigbee temperature sensor in a cabled probe.

I use HASS.agent to help manage my Windows desktop and expose various sensors to HA. It can suspend or hibernate the system. It does use MQTT as its connectivity plane.

You get easy access to their addons with a VM (aka HAOS). You can do the same thing yourself but you have to do it all (creating the containers, configuring them, figuring out how to connect them to HA/your network/etc., updating them as needed) - whereas with HAOS it generally just works. If you want that control great but go in with that understanding.

Yes I simplified. Some(? I’d hope all but probably not) new fobs do turn off (ignore the car broadcast) if they are not moved for a time. I proved this to myself with my 2020 car by putting my keys down by my car door, I could only unlock the car for a minute or two after I put it down, after that keyless entry didn’t work until I disturbed the fob to wake it up.

This is to mitigate the relay attack at home (and I’m sure other times, like if the key is in a purse), one avenue was that attackers would count on people hanging their keys by the door, so accessible to selective standing on the stoop with a relay. By turning off at rest they can’t be exploited this way.

Older fobs never turned off - so they are constantly broadcasting the signal for the car. Newer fobs do turn off when at rest so they’re less risky, but if say it’s in your pocket it’s constantly moving so someone could still relay it to steal your vehicle, assuming they get close enough to you.

The faraday bag is good for older fobs or if you think you’re at risk of a key relay attack.

I have a bunch of Tuya and Aqara buttons from AliExpress and I’m happy with them. I haven’t found anything similar on Canadian Amazon at least.

BTRFS has RAID built into the file system - instead of using MD you use BTRFS profiles which tell the system how to handle data.

For instance

• file system data (critical for the file system to function): raid1c3 which means 3 copies of core P file system data on 3 different devices
• user data: raid1 (so duplicating all your data on two different devices)

With this set up you could lose one device (of n, the total doesn’t matter), and not lose any data, and still be able to boot to recover with too much hassle.

BTRFS does block checksums, can scan for bit rot and recover from it, and generally tries to make your data safe. It technically supports raid5/6 for user data, the issue is around unclean shutdowns and a potential write hole where you could lose data, but if your system has a UPS backup and is on a relatively recent kernel it’s not any more dangerous than MD raid5/6 as I understand it.

You’ll need to use | float(0) in templates. All state values and attributes start out as strings. Also setting a default value in the float(#) cast will ensure templates don’t break when the value is invalid.

That means use this style: {{ state\_attr("light.kitchen\_sink\_ceiling", "brightness") | float(0) }}

We need more information to recommend anything. Do you need high voltage switching? Do you have zigbee, zwave, or only wifi available? How much integration or local on device control do you actually want or need?

Ohhh I haven’t seen that Zooz relay before, hopefully I can get it in Canada. Going to see about replacing the Shelleys I’ve got deployed then

The thermostat should be a passive device and is really just a relay on its own. It could be connected to the switch pins on a Shelly.

I don’t know of a compact zwave dry relay though - so this does mean 2.4ghz wifi.

If it’s like one I rented a few years ago, yes the thermostat just controls a fan, and the radiator is always hot or cold as it’s controlled by the building. I’d be inclined to use a Shelly or other dry relay with a virtual thermostat in home assistant now.

It comes down to what are the developers willing or able to support.

For smaller teams they usually don’t want the responsibility of maintaining the package for distros, and HA developers have chosen to not support that option themselves. In their case I see it - what’s the benefit or incentive to them to maintain packages and the associated support costs or headaches. Containers mean they get a known state and don’t have to try to support unknown environments.

Some interested people can maintain the packages for their chosen distro - for instance I see one for Gentoo but it’s only up to 2024.6. It’s the first that came up in a search but there are likely more too supported by the community.

In my case, I also think that using HAOS on a dedicated box has led to a more stable experience as it’s not competing for resources on my other hosts, and attaching devices to it is much simpler. I think encouraging a solid base for people means a better experience overall when to be honest it’s hard to get started with it to begin with for many people.

The phone or browser may be using DNS over HTTP (aka DoH), check if you can disable it for the wifi network. You may have to disable it on the phone or browser to get your desired behaviour - look up directions for your browser.

This. Basically few addons are ‘fire and forget’, almost all of them need some sort of configuration that’s listed in the Documentation tab, or in the add-ons repo. You’ll need to read up on it and look at the Configuration tab to set whatever you need to allow it to work.

I do this with my desktop - I work from home so it’s really nice to have my PC ready by the time I get down to it. There’s a workday integration too, set your typical schedule and it’ll be true when it’s a workday - with a motion sensor as the trigger as my start time varies if I have meetings In the morning.

This is one of the first things I set up with HA for fun but the convenience is really nice.

If it’s logs, there’s a package called log2ram - it’s designed for small form factor systems to reduce writes to SD cards but does apply anywhere you want to log but not hit disk immediately. It syncs logs to disk on a regular basis so you don’t lose much if the system crashes.

From a Linux command line it would be the command called arp, you need to add a static arp entry. I don’t know how that works on sense, but on Linux it would be something like arp -s IP MAC

Maybe there’s a module in opnsense to help. The way I’ve done this before is using a machine connected to the same network at my target to wake up by logging into that machine and issuing the wake command.

WoL packets are usually sent to the ip broadcast address for the network as they’re not ip based. I don’t know if this would ever work well across networks. Can you do send the wol packet from the opnsense router instead? Does it work then?

If you’re sending it to the IP of the server, it likely works soon after your turn the machine off because the ARP entry hasn’t timed out yet, but once it times out it won’t work anymore. The router doesn’t know how to get to the machine. You may be able to add a static arp mapping to get it to work long term.

Yes, based on my migration from a Raspberry Pi to a mini x86 pc. A full backup contains a complete snapshot of that moment and all your configuration, history, and all add-ons and their data. I think HACS came across too, though I can easily be misremembering.

The restore looked like it tried to do everything but my large database add on (PostgreSQL) gave it grief so I ended up restoring components separately. The backups did work overall though, and after a few reboots everything worked.
