Home Assistant MariaDB Install and System Monitoring

[@redwireless]

New to HA ,and this channel has definitely been our #1 online resource: *** TIP *** not sure if this is known to all, but as a 'newbie' we found out the hard way: if you set up your 'super secure password' utilizing the character '@' in it (for example, to change the letter a,A with @, as in '@ppl3' instead of 'apple'), the database, logs, records, history will NOT START! Only after looking into the logs for an hour, we discovered the @ is used in the [>]recorder code as a designator for db/server location! So the only @ character in the [>]db_url line MUST BE the one between your 'password' and 'core-mariadb' FYI! :D

[@spinnercruz]

Thank you, this really helped me out Jose

[@MattHawkinsUK]

Just switched to MariaDB using this video after corruption with my SQLlite DB. Really appreciate the clear no-nonsense delivery of information. Surprised how easy it was to do. 5 minutes and all up and running.

Thanks for the tip on the Maria DB, even though I have been working with HA since 0.4, I still gain a lot of ideas from your channel.

Thank you, your a true veteran of Home Assistant! Appreciate the support!

[@G8YTZ]

@@EverythingSmartHome Hi! I have an update on the Maria DB and a possible issue. I've had to back out to my previous configuration. My hardware is an INTEL NUC Celeron 7CYJH with 8GB Ram and a 128GB SSD and I'm using NABU CASA. Basically Alexa Media TTS fails to work with Maria DB, at least it keeps requesting re-authentication and then the same again a few hours later. I backed out to the previous snapshot and all ok again. Very strange. I'll try installing again to double check, but has anyone else seen this issue?

[@EverythingSmartHome]

Hello! That is strange, MariaDB doesn't have anything to do with the workings of HA, it only handles history and log book data, that is all. No integrations or anything is stored in the database. Did you check your logs before reverting? I've seen others complain that different things aren't working but it's because they've made an error in the mariadb setup and HA can't start properly, preventing it from loading components after the recorder. The HA logs should confirm this

[@G8YTZ]

@@EverythingSmartHome I will repeat the process to be 100% sure, but it was the only change I made. I have a policy of making one change at a time exactly for this reason, I'll feed back again. No doubt of the performance improvement on the NUC though. I was wondering if I could easily use a remote Maria DB as I run one on my Synology DiskStation for my Amateur Radio logbook.

[@EverythingSmartHome]

Definitely check the logs after migrating to see if there any issues, find us on discord if you need some help and we can try to get you sorted

Good info! I had recently set this up but now realized I’ve made some mistakes so will be going back and correcting them like going to an SSD card lol.

[@MartijnKrijgsman]

Love your video's just wondering why you would put you db_url in the configuration.yml instead of only a reference to the secrets.yml seems the better place like that

[@traxeonic3600]

I actually do this in my configuration. the entire parameter is in the secrets.yaml file. then I reference it in the configuration.yaml like: db_url: !secret mariadb_url .... while secrets.yaml is not any more secure than the configuration.yaml file since they are colocated and not enciphered, it DOES allow me to do things like backup everything to github and not push the secrets file to github. It also allows me to easily share configuration samples with people without having to scrub them.

I'm surprised to hear that SQLite isn't performing well (or reliably) considering Home Assistant only has 10 days of data and this should be way, way below any threshold where performance is suffering. Of course i've never analyzed the queries (the achillieas heel of all SQL database apps) but was wondering if you had any metrics on how MariaDB had improved things.

Tried a lot, but can't get to boot from SSD on RPI 3. So only did I start using the data disk feature. So is it ok to use Maria DB on my existing setup? Or will i have to boot from SSD (possible on RPI 4's but hardly available in the market right now)

[@sorinescu123456789]

Big problem when the supersecure password has the @ character included. The recorder handshake was not happening, and no data was accumulating. No documentation that I could find. Changed the db name, changed the core-mariadb with the IP address, and eventually I noticed that there was a @#$@ sequence in the yaml file that didn't look good at all. Beginner's mistake, I guess...

[@MattHawkinsUK]

I wouldn't say that was a mistake on your part. No reason you wouldn't think @ was OK. It was only chance that I didn't think to include that character in mine. It (the HA interface) should make it clear in the settings if the password is restricted to a set of special characters.

If you're seeing issues with recorder, logbook etc after switching over to MariaDB; try a shorter password and remove any symbols, restart after changes.

Is it easy to migrate homeassistant from an SD card to SSD? And if I run from an SSD shouls I use the 64 bit version? And can you make a guide how to? I'm currently running on an pi4 4GB model. Thanks for the video's!

[@EverythingSmartHome]

Thanks for watching! Yes it's easy, I would just use the snapshot restore feature and do a fresh install. Hope that helps!

Where is the new MariaDB file database located (in case you might want to back it up seperately)?

[@carlnakamura4861]

Great video! What are the limitations on password complexity for the MariaDB instance? if using a password with only characters and numericals it works but a password ending with an exclamation mark seem to be mis-interpreted by the configuration.yaml. i.e. setting the password in the MariaDB config works but HA can't connect to it using the password in the db_url.

[@EverythingSmartHome]

Thanks! Yep it will most likely interpret it as an "include" try doing it in quotes

[@carlnakamura4861]

@@EverythingSmartHome thanks i will try both single quotes and double quotes as I don't know yaml syntax by heart

[@carlnakamura4861]

@@EverythingSmartHome I had to revert to a password with no exclamation mark at the end. The db-url didn't work with either single or double quotation marks surrounding the password...

[@EverythingSmartHome]

That's annoying. You could try putting it into the secrets file but I'm guessing it would just do the same

@@EverythingSmartHome Thanks I'll try and test to but the "plain" password in the secrets.yaml file anyway just doing things step by step. Thanks again for the great video and channel!

Thanks for another great video! Quick question for you though... I am running on a Raspberry Pi 4 4GB. I do have a 256 GB M.2 NVME SSD in a usb 3.0 enclosure. Frenck had mentioned instead of changing the eeprom to boot from USB 3.0, you can just leave it booting up from microsd and write all additional data to the USB 3.0 drive. Any idea how to do that?

[@EverythingSmartHome]

Hey thanks Anthony! You could do that, all you would need to do is mount the USB, however if your going to the hassle of plugging in an SSD, why not just boot from it instead? Was there another reason you don't want to?

[@97ynoT91]

@@EverythingSmartHome Not necessarily. Still learning Linux and the like , so working on getting more comfortable with it.

[@BrendanBerg]

@@EverythingSmartHome I think this is a topic for the next one! What's the best way to get booted from the SSD?

[@EverythingSmartHome]

I don't have a Pi 4 to be able to use at the moment but perhaps I can't ry get a good of one!

How can i add configuration validation in server controls?

Is MariaDB bad for USB drives as well or is it only bad for SD cards?

[@EverythingSmartHome]

It's generally as bad, USBs and SD cards are made from much lower quality flash than say an SSD

[@naronaroyan323]

@@EverythingSmartHome So you wouldn't recomend me to use MariaDB for my HA that is installed on a flashdrive? Was thinking of using NGINX which I think is using MariaDB...

[@naronaroyan323]

@@EverythingSmartHome Also is MySQL(I think the defult for HA) better when it comes to this issue? Because I really want to use my flashdrive for HA.

Why sqlite less reliable ? Mariadb without high avail cluster is really more reliable ??
