Intel NUC Kit DN2820FYKH surplus to requirements running Home Assistant 0.93.1 on SSD

 

Runs sweet. I had over 50 devices connected to it through Home Assistant with the MariaDB add-on and the CPU never went over 10% with HA restarts taking around 1 min. Time to upgrade your Raspberry Pi and ditch that MicroSD.

Looking for $190 with free postage nationwide.

Did you ditch HA or are you upgrading?

I'm always on a quest to make everything run faster! Can't help myself. Definitely did not ditch HA, I'm addicted! Upgraded to i3 just to see what that did. 🤪

haha, fair enough.

 

Addicted too here. Moved from Pi to a NUC and only regretted not having done that earlier.

 

Running 20+ Phillips Hue, some Z Wave switches, DIY garage door opener and 2x Automated Aircons...

 

Good fun!

What aircon unit do you have and is the HA interface home-made or off-the-shelf? I have 4 x Mitsi units that can be hacked but I'm struggling to find a use case other than ensuring they are off when the alarm is set.

One Misti Ducted system with off the shelf Wifi Controller we got installed. Using a 3rd party component (Mistubishi echonet) to communicate with it and it works pretty well.

 

The other is an old Fujitsu with a Sensibo Unit put in front of it. Works well.

 

Use case:

 

Ducted System has an issue with closed doors where the thermostat doesn't sense the change in temperature happening in rooms that have their door closed. You run the risk of overheating bedroom in the evening. To avoid that, I have a temp sensor in each room that will cause the Ducted System to shut down if overheating is detected (to a configurable value, currently 24)

 

Similar but with the cold, in Summer.

 

Other use case is turn it on automatically before we are due to come back from work if temp is < X

 

Stuff like that. I realise that most OEM apps can let you put them on a schedule but I'd much rather have all of that logic sitting nicely in Nodered, being backed up, than it 3rd party apps on my phone.

What was slow with the Pi? I'm currently running HA on the Pi 3 with a few connected Z-Wave devices. I love speed, but haven't noticed anything particularly slow. Just surprised at how big a difference you guys make the upgrade sound? Did you have decent SD cards in the Pi? (Makes a big difference.) HA doesn't exactly seem to be very demanding. Using HA to turn on lights via mobile phone seems near instant for me.

Setting up anything on HA usually involves a few restarts and my Pi would take several minutes to restarts which was frustrating. NUC would restarts HA in less than 1 minute. Much easier to diagnose a problem in that case.

 

Also, if you want to bring up things like HA history (that graph that shows you the historical state of all your entities), Pi would take ages to pull that data where using NUC, it's much faster.

 

What really did it for me though is that my HA corrupted itself twice within 4 months (micro SD cards do fail, eventually) and I had to rebuild from backup. If you end up depending on HA to run the house smoothly (and keep the wife happy) then I think it's worth investing in something  more reliable than a Pi.
