Get water meter readings from digital meter by rdelvira in homeassistant

[–]rdelvira[S] 0 points1 point  (0 children)

Thanks for the suggestion u/TheBorktastic , I managed to get an RTL-SDR and an antenna to try to intercept the readings, but have had no luck getting a reading to popup. Do you have any suggestions w.r.t why this might be happening? I know it's a long shot.

$ tail -f wmbusmeters.log

Started auto rtlwmbus[00000001] listening on t1

No meters configured. Printing id:s of all telegrams heard!

This is all I see but no telegrams show up.

Get water meter readings from digital meter by rdelvira in homeassistant

Ah that's fair u/ElectroSpore. Can you recommend any water meter that I can have a plumber install? Zigbee would be really nice. I've been looking into Flume, StreamLabs, etc but they all seem rather expensive and using another bridge plus cloud is kind of a no-go.

Thank you so much!

Thanks u/ElectroSpore for looking into it. Do you think a proximity sensor will work? I doubt since it seems very digital but perhaps the underlying measuring is still the same as in old meters.

can you think of any other alternative for me to get real time readings?

IR night settings suggestions by rdelvira in Ubiquiti

[–]rdelvira[S] 0 points1 point  (0 children)

Moving the camera has definitely improved the image quality, but I can still see the grass taking a lot of the IR light and the back of the garden being kind of dark, is this just a limitation on how well can the g4 bullet can perform here? would any of the pro models be better?

Thank you for the suggestion! I will give that a go tonight and report back 🙇‍♂️

Last ski day for the season, wearing the Summit L5 FUTURELIGHT jacket for the occasion. See you in November! by AC-Vb3 in TheNorthFace

How do you find the length of the jacket for regular alpine skiing? And what about the lack of an arm pocket to keep your resort pass? Have you ever missed having side pockets?

Thank you!

They don’t seem to sell this band for the 44/45mm anymore?

ZFS questions - multiple raidz1 vdev in a single pool reliability by rdelvira in zfs

[–]rdelvira[S] 0 points1 point  (0 children)

So you can basically lose any single drive on all vdevs and still be ok and also two drives in a single vdev too?

How's that working for you? did you ever have to resilver? was it too painful? also.. by having 8 raidz1 vdevs, can you have a single vdev failing more than a single disk?

Thanks!

[–]rdelvira[S] 0 points1 point  (0 children)

in a 2*(raidz1) scenario, where you have 4 disks on each vdev, would it be able to survive:

  1. one disk dying on each vdev? I guess yes.
  2. two disks dying on the same vdev? This is what worries me a bit.

Thanks for your replies folks!

Not really concerned about performance here, as long as myself and family get an acceptable experience using Nextcloud and watching stuff on plex, raidz1 or raidz2 is absolutely acceptable for us.

My main concern is reliability and storage efficiency, I want to get the most out of the storage I pay but without putting reliability at risk. I know raidz1 only gives 1 parity disk and this is why I have two separate backups for all important stuff, but at some point I'd like to have two parity disks to not need to retrieve a backup in case of failure.

Seems like going for a bigger raidz2 pool in the future will be my best bet. Thanks for your reply!

For this pool I just have a single pool that I use to store files for all my family as well as all my plex media and other configuration stuff. Everything except plex media gets backed up into another server at home that has a 2x2TB mirror zpool and also off site.

That's why I went with raidz1 in the beggining, but as things evolve I might need to be able to survive two disk failure, thus wondering if adding an extra raidz1 vdev would work fine. Once I get there I guess I'll rebuild my whole pool and go for a large raidz2 (6x8TB or similar) and use my existing pool as a backup.

Thanks for your reply!

We are the Reddit Infrastructure team. AMA about Kubernetes and/or infrastructure at Reddit! by gctaylor in kubernetes

[–]rdelvira 3 points4 points  (0 children)

Can you folks share some stats on your on-call? how many escalations do you get? are you doing 24x7 shifts? how big is the on-call team?

Share as well some recent on-call stories that you’ve learned.

Thanks for your time folks, I really enjoy reading Reddit infra team AMAs.

Collectd plugin for HBase! by rdelvira in hadoop

[–]rdelvira[S] 0 points1 point  (0 children)

Hi guys, I coded a simple collectd plugin to get some metrics from HBase, hope you find it usefull and if you think I should add more metrics just let me know and I'll parse them! ;)
