Redlib ?

On your Xiaomi first time you launched app, you can determine wether you always allow or allow on prompt (but you should still be able to manage that setting afterwards). You also need to disable battery optimization for that app and set app to be able to auto launch in background. This is at least what I do with my home assistant app to determine GPS location in background (app record every 15mn) and no issues with battery draining.

Long time I haven't used it but nova video player should do it

A complete and affordable setup that will merge anything you want inside a single app will be by using home assistant. But while it is much easier to setup and maintain than a few years ago, selling the house will require new owner to have a few tech knowledge. You also have to make sure that your setup is designed to be used by all family whatever there age and knowledge (and it isn't always simple)

Describing everything available that would make it a perfect place will take a very very long comment but here are some hint, look at ethernet cameras instead of wifi, ZigBee and zwave instead of wifi for most of the devices as those protocols are designed for smart homes unlike wifi, use as less as possible cloud base solution.

As a starter, you can check for temperatures/humidity sensors, contact sensors for doors/windows, automated curtains, switches, presence detection, lights, leak detectors, weather station, energy monitoring,...

Don't have particular case to recommend as the one I have has been printed but get one where you can add an SSD. SD card are not well suited for home assistant due to the amount of overwriting.

Je vais surtout parler de ces domaines de niches.

Celui que je préfère c'est home assistant (domotique) auquel on peut ajouter un assistant vocal que l'on peut avoir en local (ou non), l'assistant n'est pas à hauteur de ceux des big tech mais il n'arrête pas de s'améliorer et il marche déjà bien.

Je viens de découvrir Ardour (DAW), installé pour un proche sur un vieux portable que j'ai mis sous linux et ça tourne très bien.

Un que je n'ai pas réussi à prendre en main mais qui est pour autant top c'est prusaslicer (slicer pour fichier 3D). J'utilise Cura pour l'instant mais je compte bien réessayer d'y passer plus tard.

Et toi TheFrirish, quels sont tes préférés ?

ZigBee are not designed for high bandwidth applications but +1 for Home assistant

I just tried and I think they are limitations on numerous android OS.

It isn't exactly a widget but what I have been able to do is create a shortcut when long pressing home assistant app icon on my phone

To do so, go to home assistant app settings/compagnon app/shortcut Give it a name and description, not too short according to documentation (see below), next add under dahsboard

Edit: added another screenshot from settings (sorry in french but that should help). This was just a quick test, this is why I named it assist_widget. You can also change icon type

"finalement assez drôle" jusqu'au moment où on s'aperçoit que des connaissances le prennent sérieusement. Et là, ça devient déprimant.

Check HA Devs videos called "year of the voice" to know everything you have missed. Also atom echo isn't really a smart speaker, more a micro with a possible always listening mode

(not first hand experience but) Nabu casa is a way to support HA development, having cloud assistant is just a bonus, you also get easy external access and another bonus is that you don't need to setup the different addons to be able to use assist, while it is doable on something like raspberry 4, problem will be latency compare to nabu casa or you will need a more powerful device to be able to run them smooth. If you didn't bother to setup cloud assistant by yourself to avoid fees, chances are you will stick to nabu casa and it is a good thing as you are supporting home assistant development.

Have you tried to press Enter to show bios setup? (Don't have one, but that's what a quick search tell)
