It's still in development but is being built specifically with GrapheneOS in mind. Hopefully we should have a privacy focused tap-to-pay within a year.
I was actually able to use one of the temporary phone number services to get past it in the end and started the request.
Want to delete my data... log in to my account to do it... phone number required before allowing me access to delete my data 😑
I run Immich, along side about 10 other services, on my DS420+, and it runs great imo. The initial import of all my photos (40,000+) did take a long time but now that it's up and running it's more than quick enough.
You can install it directly from their GitHub repo or through Obtanium.
Go to your browser settings and to the Search section. There will be somewhere in there to add a new search engine. Add in 'https://noai.duckduckgo.com/?q=%25s' then set it as your default.
You should be able to do the same if you're using a search widget directly from your launcher as well.
Definitely Zigbee or Z-wave instead of wifi. Once you start to build out more devices you will be glad to not have gone down the wifi route.
I went with Zigbee and have Sonoff SNZB-02 temperature and humidity sensors in each room that have been absolutely flawless since the day I installed them, and they last about two years on a single battery!
I would obviously recommend them but I don't have any experience of other thermostats or of Z-wave.
I did also install smart Zigbee TRVs on each radiator but I don't rely on the internal thermostats of them as they don't accurately represents the overall room temperature.
As others have mentioned the Philips bulbs are about as good as you can get but they are also the most expensive. And that you can save money by going with the IKEA lineup but the quality isn't as good. But your third option is Innr bulbs which sit perfectly in between Philips and IKEA for quality and price.
TLDR
Philips - best quality / most expensive
Innr - medium quality / middle pricing
IKEA - lowest quality / least expensive
Note: when I say the IKEA is the lowest quality, I just mean between these three. They are still miles ahead of any of the no-name brand crap you can get on Amazon.
I use Syncthing for files/photos/videos and Nextcloud for calendar and contacts.
