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?

I’d have to check my iptables syntax again but I’m not sure you want the FORWARD between the networks unless C has a manual route to get traffic for the 192.168.15.0/24 network back via B. You just want to NAT A behind B’s IP on 192.168.38.0/24. I think the forwards are sending the traffic without doing NAT on A.

Phillips SonicCare for 20+ years. I think it’s helped me a lure with my dental care. Various models as the batteries wear out. The latest has Bluetooth that I never use but that doesn’t affect the cleaning part.

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.

Right now - easy, with the difficulty going up over time as the main Chromium codebase continues to change (and especially as it gets security updates). I think I’ve read that some variants (Brave?) have committed to supporting ManifestV2 for as long as possible, for instance with their own fork.

All that yes. The Wooting One (original that uses IR light) let you use buttons to simulate controller axes, change how hard you need to press to activate, and add second functions to keys. It was an interesting idea but I found the gaming part the original keyboard to be only usable in a limited set of games as it’s not as sensitive as a controller stick, and as a keyboard it wasn’t great either. Hopefully V1 problems, I know they had through another version of the IR keyboard, and then came out with the Hall effect keyboard. I like the idea but never could get used to it, and when the spacebar was loose I retired it after fixing it.

I’m using project boxes from Amazon, like these: https://a.co/d/4R4Dtv5 before I had a 3d printer to make something bespoke. Some of the boxes have the ESP board glued down, some it’s loose. It works well enough and doesn’t look too bad. I still use them now as it’s easier to throw everything into a box instead of designing something specific to the project.

Then to link the entities together into a device you need to mimic the auto discovery, or you just have two split entities.

I suppose you could create a template entity with the battery as an attribute to see it in the details view, but you still need the entities with the raw data. I’d be more inclined to create the device with auto discovery, seems like a cleaner way to go.

Zigbee2mqtt should do device auto discovery by default (it did for me and I didn’t have to do anything). Maybe you’ve turned something off? The alternative I can think of is to manually create and maintain device auto discovery records like https://stevessmarthomeguide.com/adding-an-mqtt-device-to-home-assistant/ shows (for example).

Try searching for your automation.entity_id - like in my case it’s something like automation.notify_washer_done (the original entity id of my automation, found via the developer - states tab). Then if I search using that in my YAML I’d see entity_id: automation.notify_washer_done, and add the context to see the full service call:

service: automation.turn_on
target:
  entity_id: automation.notify_washer_done
data: {}

Assuming it’s an automation or script your should find it in the related .yaml file and can scroll up to see the actual automation or script source.

Turned off or Turned on is the disable or enable action. If it’s changed by something in HA it should show what the trigger was too (like a user or other automation).

Here’s an example - it shows the automations that enabled our disabled this automation, and their trigger.

To prevent the automation from being changed you can rename it, that should break anything automatic that’s changing it. You can also try to chase down what’s changing it from logs (once renamed you should start seeing errors in your HA log file), or by searching for the entity_id in your yaml configuration files.

Check out the Zooz ZEN15 too if you want something off the shelf.

I use an Emporia Vue device, it uses an ESP32 internally and you can find instructions on how to flash it with esphome code onto it. No cloud dependency, just wifi.

You can get various kits for one/two/three phase mains, and monitor up to 16 individual circuits via passive current clamps.

I have actionable notifications with notify.notify service working so I’m not sure there - something sounds off.

I don’t think there’s issues with long timeouts, but realize that they won’t persist through restarts of Home Assistant, and depending on your automation settings you can control the number of instances. To disconnect the action from the running automation I often add the event as another trigger to the automation and then add logic to handle the normal trigger and the notification trigger separately. No wait needed in the automation then, just fire the notification and another instance of the automation handles the action.
