Do you have any articles discussing this? I’m interested to learn more as someone who doesn’t live there.

It’s good to plant trees, but beware of folks using it as cover to avoid more important work like actually reducing fossil fuel usage: https://art19.com/shows/the-climate-deniers-playbook/episodes/5322de3f-ffc0-4258-a890-c648f59bc195

It is expensive but that Frient keypad is what I have and it’s fantastic. Been running it for about a year now and it’s rock solid. I’ve even repurposed Nest tags to work with it.

I don’t use it with Alarmo but it would work just fine if I understand how Alarmo functions. I installed it 6 months ago and it still reads as 100% (though who knows how accurate that is). It does require some beefy batteries though so I tend to believe it. The battery reading is coming through Z2M.

Hope that helps! Here’s a helpful thread about getting it working and setting up RFID tags (I used old Nest Secure tags with no issues).

That’s definitely its focus, but if you want a very simple store it does support payments: https://ghost.org/help/ecommerce/

If you’re willing to accept JavaScript I’d recommend a Ghost setup. Pretty good platform once it’s set up and easy to selfhost. Not sure you’ll find a platform without JS for your use case tbh.
