gravity-sync VS uptime-kuma

OR I could implement https://github.com/vmstan/gravity-sync as it's last commit was a year ago but users still seem to be using it.

I run the split DHCP approach for years without issues. Having only one PiHole with DHCP Server doesn’t give you a fully redundant system. I don’t use Gravity Sync myself, but their wiki covers this case with examples: https://github.com/vmstan/gravity-sync/wiki/DHCP-Replication

the github page has a really good walkthrough and explanation

I don't have anything add to your question. But I recommend installing gravity-sync if you're going to run two piholes. It will sync up DNS entries (among other things) automatically to the second pihole when you add a entry one of them. https://github.com/vmstan/gravity-sync

If you go the 2 pihole route, I strongly recommend Gravity-Synch. https://github.com/vmstan/gravity-sync

Run Pihole on both, if DNS goes down its painful. You can sync them with https://github.com/vmstan/gravity-sync

Uptime Kuma can also monitor certificate expiration; you can also enable it to show you how many days are left until it expires.

2. Uptime Kuma

- Web terminal & live logs

I'm trying it as an alternative to Portainer and I'm loving it. It seems to fit perfectly in my flow.

FYI - Uptime Kuma supports push-based monitoring as well.

Uptime-Kuma for Watching Services

I have tunnel up and running as described on this page: https://github.com/louislam/uptime-kuma/wiki/Reverse-Proxy-with-Cloudflare-Tunnel

⭐ Uptime-kuma on GitHub

Uptime Kuma is a self-hosted monitoring service that you can use to keep track of the heath of your applications, websites, and APIs. You can configure it to watch services with different types of health checks and set up email notifications for when there are problems. Uptime Kuma also lets you design custom status pages that you can use to share public information about your service health statuses and to manage incidents.
