at least 3 times after updating Home assistant, some of the devides doesn’t work. I think this kind of things it shouldn’t happen. I would like to trust on my system and after this last update , I`m not going to trust on … HA system as a reliable
I’m using Ha with m2qtt
I use mqtt extensively. I have had no issue with it for many years.
Seems to be specific to your system. So you will need to provide a lot more information if you want to resolve this.
Specifically which devices are not working?
Not working in what way?
Which mqtt broker are you using?
How is it set up?
What method are you using for authentication with the broker?
What errors do you see in the core and mqtt logs?
Using it from Aug 14, 2017.
No problems with mqtt.
Sometimes updates cause issues with other settings.
But these can all be resolved.
First thing to do before updating is read the breaking changes, this will tell you if anything is likely to break. There are always breaking changes but the reality is not many effect every user every time.
The next thing is if you want a 100% stable system only use good apps and approved integrations, this will help but not guarantee.
Third this is to not bother with updates, your system will still work if you never update it.
But most importantly if you want a 100% stable system that never breaks or needs updating then HA is probably not your best choice.
Using these tips I have not had an issue for the 7 years i have been using HA.
It’s a great pitty that you says: “If you want a 100% stable system HA is probably not your best choice”. that’s the question. It should work 100% perfectly. It’s only my opinion. Has happened three times that after and update, some devices were no recognized, and some other suffers changes. This shouldn’t be happen
Write “2026.2.3 core Home assistant problems ?” in a IA platform… you will see
It’s an open source project maintained (mostly) by volunteers.
If you want software that is:
That generally costs a lot of money, where as for most of us HA is free.
On a more constructive note:
Just run HA under docker along with good backups of the config directory.
If you set it up right you can roll forwards and backwards at will so HA doesn’t ever break unexpectedly / you get to manage when it gets broken so you can fix it at your own pace.
It’s hard to diagnose something when flying at 10,000’
HA is packed with diagnostics tools like device activity, event traces and logs. Those have not been presented here, neither has a detailed description of the problem other than “updating breaks devices and mqtt is somehow involved”
The community can only help you as much as you help yourself.
Hi Jose, I will try to give you good advice, just as the other users here.
As you probably already know, HA is software, free, open source and capable of doing almost everything.
I don’t think that there is any home automation/smart home platform that is developed at the same speed by hired developers as well as A LOT of volunteers.
This can potentially cause problems.
One of the beauties of HA is that you can install it on almost anything that resembles a computer.
If you have some experience, you know that making something that runs on a variety of systems is not that easy.
I am using HA for 6years now and my system is rock-solid.
If it was not like that, I would not use it anymore so I understand that you are disappointed.
This is a very helpful and active community of volunteers and if you ask for help and keep in mind some rules about daily, normal decency and provide ‘us’ with details, you will most likely get help to solve your issues.
Yet, you don’t react to the first attempt by a moderator and highly skilled person to help you.
Instead you jump on the last part of another post, also ignoring what is mentioned before that to, probably, vent your frustration, opinion, …
I do understand that you are not that happy when things break and you have automated already a big part of your house.
That’s why I started very slow with HA and gradually added things.
It’s up to you what you do with our replies, trying to help you or staying stuck in your frustration…
To be clear: this is to help you, not criticize, and sometimes other opinions can feel harsh.
Haffun!
Edit:
1: with so many people using HA, there will most likely be more cases like you.
2: using AI for something like that… 
There is NO SUCH thing as 100% perfect software. Period. End of story full stop.
Humans (and sloppy AI) write code.
THEREFORE humans (and sloppy AI driven by humans) make mistakes. In ALL code. (See why Linus Torvalds has a job… if humans didn’t write bugs he wouldn’t need to maintain Linux)
Humans (and sloppy AI driven by humans) make mistakes in deployment (ask CrowdStrike about that)
No single person writes all the code for HA and no single person is capable of seeing every single scenario therefore mistakes will happen.
With your assumption above you can only be disappointed. Bugs happen. Fortunately the volunteer devs working HA and the full time staff do a good job fixing things when they’re found and accurately described. I’m sure if you describe your issues the community would live to help.
What the OP is saying is that they want a closed ecosystem (other manufacturers should not be able to mess things up), that is expensive (quality testing takes time and money), based on oldfashoned technology (changes break things and new stuff is unproven) and maintained by payed, trained professionals (regular users are the biggest hazard of all). So think The KNX advice is as close as you can get.
