I replaced (sold) my coral usb late last year after using it for 3 years. I upgraded my home server and wanted to go M.2 and noticed that frigate started to support a new chip, with many times the performance of the coral. I went with a Hailo-8. It’s been flawless.
Recommendation: use the .deb driver that Hailo provides, it gets installed via dkms and survives kernel updates.
I used the ecolink device for some years until I discovered the Zen55, which I implemented a few weeks ago. The ecolink stopped detecting CO after I changed my interconnected alarm system to a new Kidde model as the old one started to give occasional false alarms. The ecolink was also unable to clear the CO Alarm once triggered with the old Kidde model I was using, it required removing and reading the device from the zwave network.
Zen55 worked perfectly, able to differentiate CO and smoke signals and auto-clears when the alarm condition stops. It requires no batteries.
Fair comment, I should qualified my answer: I use an ssh tunnel with auto-reconnect option, wrapped inside a systemd service. In all this years, I still have to run into a problem that wasn’t external (server down, no internet at home etc) I agree that wireguard is the proper solution however it requires a lot of extra configuration and support in both ends, which now is prevalent but not so much 5+ years ago. Also for a single port solution, ssh is so much simpler, practical and reliable, you only need an ssh user at the other end.
ExecStart=/usr/bin/ssh -NT -o ServerAliveInterval=60 -o ServerAliveCountMax=3 -o ExitOnForwardFailure=yes -R localhost:YOUR_PORT:localhost:YOUR_PORT SOME_USER@YOUR_SERVER
This. Using simple ssh tunneling with port forwarding in a similar scenario. Working flawlessly with zero maintenance for 5 years and counting. Very reliable
For Music and streaming, specially for hi-res audio. SACD etc streaming, take a look at lyrion music server. The best solution of the myriad I tried self-hosting. Supports podcasts and audiobooks as well
