I recently switched a bunch of nginx configs to the opnsense Caddy plugin. It is easy to configure, but in my opinion it lacks the ability to change settings beyond the basics. It isn't helpful either that the plugin developer fails to recognize any other use case than the basics. It disqualifies the plugin for everyone with a little bit more complex setups.
I have recently setup my paperless-ngx instance and have uploaded all my scanned documents. Now I have to tag all that stuff which seems like a lot of work. So I'm looking into paperless-ai... 🧞
The easiest thing: We use a motion sensor to automatically turn on the light for the stairs. You wouldn't need Home Assistant for that, but with a little more configuration you can adjust the light levels and colour temperature based on the time of day (not as disturbing at night). We have two rooms which have problems with humidity in one a fan is automatically turned on (basic) in the other a dehumidifier is triggered based on the outside and inside temperature because there are large windows which are producing a lot of condensation otherwise. Now the really specific stuff: My daughter has Diabetes and we need to manage her blood glucose levels. There are alarms but ideally you would act before they are triggered. So we hooked her blood glucose levels to a light in our bedroom which turns on if her levels are getting out of bounds at night. That way she isn't woken by the alarm, but by one of us and can go back to sleep much quicker.
That's easily Home Assistant. It got me into the whole home automation stuff and I have gradually included more and more parts into it - including some health related stuff. It really makes my family's life easier and helps us organizing it.
That's the way to do it. The problem is that the request originates from the browser of you website visitor. You need to open a path for them to you media server. Nginx and it's reverse proxy functionality is exactly what you need for that.
Over-working is a common thing in Japan in general (this is oversimplifying things of course). So I wouldn't be sure the anti crunch movement has reached Japan's part of the industry fully.
There are lots of cheap Zigbee (multi) buttons available. If you want something a little bit fancier I can 100% recommend Home Buttons. You can either build it yourself (3D printed enclosure, custom PCB) or buy one already built for you. They each fancy an e-ink display you can configure with Material Design Icons (or even custom text in case of the bigger one). They integrate into Home Assistant via MQTT and can be fully used for any automation you would like. You can even change the 4 or 6 button labels using Home Assistant.
I totally understand your concerns. We just don't have such cold winters here in Germany. And I also understand your point more (also after having read your other comments). If the insulin vial in question is a spare it will most likely not being noticed if it freezes until it is needed.
In theory you could use the Bluetooth sensors of the companion app which can be used to detect BLE beacons. But that would require a special Bluetooth device that activates once a threshold temperature has been detected. Maybe such things exist (I'm thinking of (food) supply chain monitoring), but I am not aware of any.
I know this is technically not an answer to your question, but as a fellow T1 diabetic (for 20+ years) and dad to diabetic child (currently 2½ years old): Is this something that regularly happens to you? I don't know where you live, but in over 20 years of being a T1 diabetic I never had a vial of regular insulin go bad. I don't have to worry about the cost of insulin as my insurance would without any questions replace any medications gone bad for me, but I understand that this is a luxury not everyone shares.
There are products (but I have to assume you are aware of this) that can help you with the temperature safe transport of insulin for everyday use (basically insulated pouches with an integrated cooling pad). That may be something you can look into if this is something you need to worry about.
Then he shouldn't have asked a question if he isn't open for answers. If an answer is obviously wrong or dismissive of some important detail I would understand it. But if the complaint is It's not a one-click-fix or I don't understand what you're talking about then that's the best way of not learning anything and not solving the problem.
Google Reader was such a great webapp. This and Google Listen are the two Google apps I miss the most.
