I’d rather have both on a single unit. - Obviously the 230V 16A capability as that’s what they’re wired on and even if I don’t have 3kW elements on the floor it’s what’s needed to meet the code

I have a feeling that finding a smart thermostat with this kind of load capacity, on three separate circuits no less, is going to be a tall order. Are you savvy enough that you could wire up a system that uses a regular thermostat to control your floor heating via relays or contactors?

Yep. Split tunneling has been a standard option for a long time.

Wireguard. Wireguard is fairly easy to configure and keeping your setup behind the firewall is much less headache in the long run.

First rule of hosting publicly available services is “Don’t. Unless you absolutely have to.” Second rule is: “If you have to, do it very carefully.”

Thank you! I think that actuator is exactly what I need.

I don’t get as much into automating for the sake of automating. Personally, I prefer technology that makes my life easier. Anything “smart” in our house has to be manually overrideable.

That said, one thing I’m working on automating is the HVAC. Eventually I’ll have the Central heat, central humidifier, and whole house fan controls all integrated with HA. My goal is to maximize both comfort and energy efficiency. Being able to maintain the comfort level by automatically switching between A/C or fresh air (via the whole house fan) would be pretty cool (figuratively and literally).

What kind of devices are you using for a router and wifi?

My server is my desktop development computer.

This alone can be the source of innumerable problems, and not just for Jellyfin. Your workstation should have more than enough resources but using it to host services can create major headaches. You don’t want to host a service where the environment has the potential to change frequently, which it will with a dev workstation. I would strongly suggest using a dedicated server for self hosting. Even if it’s just a Raspberry Pi. It helps eliminate so many issues.

It runs transmission with ~300 slow torrents doing about 1MB/sec, but I always have to shut that down because with transmission running, jellyfin android app won’t even load the main screen, it just sits there frozen.

This is worth investigating. There’s a bottleneck somewhere and I doubt it has anything to do with Jellyfin.

Are your services running in containers, VM’s, or natively? What does your home network look like? Is everything just running through single a Wi-Fi/Router?

Maybe if you would tell us a little more about your setup we can help you figure out what the problem is.

Do people do that kind of thing just for the lulz? I have no reason to believe anyone would actively target me for anything like this.

They most definitely do. Some people get some sort of sick joy out to of being a PITA. I’ve had it happen to me. You’re very unlikely to become the target of a DDOS (distributed DOS) attack since that takes a lot more effort to execute successfully and there’s no payoff in this situation. But, isolated DOS attacks are more common than you might think. Whether you can defend against one depends on how much bandwidth you have but probably more on the firewall you’re running. If you have a WAN facing firewall capable of detecting and dropping connection attempts that follow a malicious pattern without choking, you’re probably not gonna have a lot of issues if any.

The level of obscurity also helps minimize your likelihood of becoming a target. Just keep your servers and any device firmware up to date.

These are just some risks you might run into. I wouldn’t necessarily consider them showstoppers. Just things to be aware of what could happen, not necessarily will and try to take preventative measures. To be honest, you’re probably going to get more trouble from your relatives than you will from a malicious actor.

Denial-of-service attacks or risk of someone compromising your server and therefore network via a vulnerability. Possibility of an attacker using your server for other malicious activities if they manage to compromise it.

Don’t get me wrong, your server would be a teeny tiny fish in the sea of internet connected services and probably of little interest to most hackers. But, if you expose the door, it’s gonna at least get knocked on.

Security issues aside, you will now be ‘tech support’ for this service and they’re going to complain at you any time it doesn’t do what they want it to. Just make sure you’re ok with that.

Not much else you can do without checking the Jellyfin logs. It could be a transcoding issue. Could also be permissions or something else altogether.

What OS is your Jellyfin server and the file server running? Are you running Jellyfin w/ Docker or natively?

Also, have you checked the Jellyfin logs for any errors?
