My network topology. I think I should get a Fritz!Box do the whole IPv6 prefix delegation, switch out the UniFi switch for a MikroTik router, and then flash OpenWRT on the UniFi WiFi 6 Lite APs. More freeeeeeeeeeeeeedom.
Heh my Wahoo Tickr was in the washing machine again so I went to the local running shop and got a Polar H10. I don't run, and it's 20€ more expensive than online but oh well, I most likely won't be without a HR sensor tomorrow.
