I want to receive a notification when someone rings the doorbell at my front door. For this I can buy all kinds of expensive (wireless) doorbells, but I want to use the existing wiring. Because I use Home Assistant for all kinds of automation at home, I also want to integrate this into Home Assistant. […]

By default, every Google device uses the following configured DNS-servers: 8.8.8.8 8.8.4.4 But I don’t want my guests, who can use my WiFi, to let Google phone home and give information about who visits my network. I use iptables to block those DNS-requests. The firewall rejects all the DNS-requests that would be sent to Google. […]

For that reason I switched from Certbot to acme.sh. With acme.sh I can generate ECC certificates, without having to generate all kinds of extra files before […]
