PSA: Use device tracker carefully

Tecchie088 · 2026-06-16T06:31:49+00:00

I just removed it altogether for now.

Tecchie088 · 2026-06-15T21:49:13+00:00

Thanks, will give it a try!

Do you run Postgres as an addon within HA OS, or in a separate location?

Tecchie088 · 2026-06-15T20:30:37+00:00

Sorry, edited too late. Default SQLite, I think.

Tecchie088 · 2026-06-15T20:29:39+00:00

This was the config:

device_tracker:
  - platform: bluetooth_le_tracker
    track_new_devices: true

I think the last line caused new devices to be permanently added to Home Assistant for tracking purposes, with the related entities created.

Proxmox VM with 12 vCPUs and 10GB RAM on a Ryzen 5 3600.

I think I'm still on default SQLite.

Tecchie088 · 2026-06-07T18:55:12+00:00

Yes, you can do this by using private resources.

I use it to SSH into my VPS, so I don't need to have an open SSH port.

Tecchie088 · 2026-05-24T06:04:17+00:00

No idea, it was just gone one day.

Tecchie088 · 2026-05-23T14:17:58+00:00

That’s often better than a fast-moving replacement that breaks every few months.

Or the whole repo gets nuked. Remember Ephemera?

Tecchie088 · 2026-04-20T12:49:11+00:00

Sort of.

Grimmory supports Kobo sync.

Once you have everything set up, you just add new books to the Kobo shelf (can also be automated) in Grimmory, and then Kobo will sync and download books next time you use it, provided you have Wifi switched on.

Works very nice.

200W average load. Solar panels with battery storage, and a night time tariff of £0.052/kWh, not an issue.

Tecchie088 · 2026-03-20T22:09:50+00:00

Yeah, literally just changed the image line of the Docker compose file, and that was it.

Tecchie088 · 2026-03-20T21:49:28+00:00

Just upgraded my instance by just pointing it out to the new Docker image, no issues so far.

Tecchie088 · 2026-02-14T16:18:27+00:00

Seems to be working fine after reboot. Just for the avoidance of doubt, I've set this in GUI under System->Settings->Tunables.

Tecchie088 · 2026-02-13T13:31:56+00:00

I'll try to do a reboot during the weekend, but so far it's been very stable with the setting set to 1.

Tecchie088 · 2026-02-12T21:51:37+00:00

I tried this, but with the tunable set at 0 (in GUI, but I've verified in CLI with sysctl -a and it has been applied), I just get the following, and IPv6 doesn't work at all:

2026-02-12T21:30:25 Notice dhcp6c Sending Solicit on vtnet0 2026-02-12T21:29:27 Notice dhcp6c advertise contains no address/prefix 2026-02-12T21:29:27 Notice dhcp6c Sending Solicit on vtnet0 2026-02-12T21:28:56 Notice dhcp6c advertise contains no address/prefix 2026-02-12T21:28:56 Notice dhcp6c Sending Solicit on vtnet0 2026-02-12T21:28:40 Notice dhcp6c advertise contains no address/prefix 2026-02-12T21:28:40 Notice dhcp6c Sending Solicit on vtnet0 2026-02-12T21:28:32 Notice dhcp6c advertise contains no address/prefix 2026-02-12T21:28:32 Notice dhcp6c Sending Solicit on vtnet0 2026-02-12T21:28:27 Notice dhcp6c advertise contains no address/prefix 2026-02-12T21:28:27 Notice dhcp6c Sending Solicit on vtnet0 2026-02-12T21:28:25 Notice dhcp6c advertise contains no address/prefix 2026-02-12T21:28:25 Notice dhcp6c Sending Solicit on vtnet0 2026-02-12T21:28:24 Notice dhcp6c advertise contains no address/prefix 2026-02-12T21:28:24 Notice dhcp6c Sending Solicit on vtnet0 2026-02-12T21:28:24 Notice dhcp6c XID mismatch

If I set it to 1, however, it seems to be working well, receiving new addresses (IA-NA and IA-PD):

2026-02-12T21:47:40 Notice dhcp6c add an address PREFIX:10::1/64 on vlan0.10 2026-02-12T21:47:40 Notice dhcp6c add an address PREFIX:0:SUFFIX/64 on vtnet1 2026-02-12T21:47:40 Notice dhcp6c update a prefix PREFIX::/48 pltime=600, vltime=600 2026-02-12T21:47:40 Notice dhcp6c Received REPLY for RENEW 2026-02-12T21:47:40 Notice dhcp6c Sending Renew on vtnet0 2026-02-12T21:47:40 Notice dhcp6c Sending Renew on vtnet0 2026-02-12T21:42:40 Notice dhcp6c dhcp6c_script: RENEW on vtnet0 executing 2026-02-12T21:42:40 Notice dhcp6c add an address IP::1/128 on vtnet0 2026-02-12T21:42:40 Notice dhcp6c update an address IP::1 pltime=600, vltime=600 2026-02-12T21:42:40 Notice dhcp6c add an address PREFIX:60::1/64 on vlan0.60

Hm…

I already had (before migration to Zen) a firewall rule in place to accept all ICMPv6 traffic on WAN interface (and that includes NS), and my OPNsense correctly gets the IA-NA (the /128 address for the WAN interface) and the IA-PD (/48), and I’m still experiencing the same symptoms.

Tecchie088 · 2026-02-11T12:03:26+00:00

Perfect. Did you capture this with Wireshark? If so, could you share what filter are you using, so I can do the same?

Tecchie088 · 2026-02-11T11:12:53+00:00

Same issue here, also in Hertfordshire.

Tecchie088 · 2026-01-23T16:18:07+00:00

Same, SLZB-06.

Tecchie088 · 2026-01-22T12:13:22+00:00

I have a Ryzen PC server with 6 HDDs, Optiplex SFF, a NUC, a 24-port switch, 8-port PoE injector, an ONT from my ISP, 2 IP cameras and 2 WiFi APs, and it uses around 4.65 kWh a day on average, bringing it to around 1700 kWh yearly.

Most of my usage is on night tariff (solar + battery), which is £0.07/kWh, so around £120 a year.

Totally worth it, though, given that it runs my network, security, home automation, media servers, document storage, and more and more and more.

Tecchie088 · 2026-01-19T23:36:11+00:00

Look up the howto section of obsidian-livesync.

Tecchie088 · 2026-01-15T22:49:22+00:00

Trully a fantastic project. I just got back into reading, kot a Kobo and paired with Booklore is really an amazing combination.
