I installed two 1TB 2.5" (SATA 6Gb/s, 5400 RPM, 8MB Cache (Western Digital WD10SPCX) )HDDs. Set up as Raid 1. I let the HC4 do the Raid1 mirroring. It only took a few percent of the HC4 CPU as it was bringing in 2.1TB of data files. (Note I used separate RaspberryPi 4B to host the OwnCloud - the Pi showed about 50% to 75% to 80% CPU while bringing in the files over 1Gig ethernet). Note the Pi and HC4 were connected with 1Gig ethernet. In Owncloud selected External Storage so Pi can see HC4 with SMB.
I ran the HC4 and the Pi to the same router (which had four 1Gig ports). Then my two laptops could do the OwnCloud backup through Wifi to the Wifi router(that also had the four 1Gig ethernet ports). It can back up 1GByte from Laptop through Wifi to router to Pi to HC4 in about 10 minutes. Very pleased with the result. Can drag a windows folder(that has folders under it) to the OwnCloud External storage icon and it does the backup. If it finds any duplicates(from previous backup) it lists those as a duplicates. Just check one box that says just keep the most recent and it will overlay the old files on the HC4 with the new ones.

Out of the box and plugged into my x86 Home Assistant PC. Worked perfectly for my needs.

I have yet to test it for matter over threads, but it replaced my previous zigbee antenna with no problem whatsoever.
Some fiddling was needed in homeassistant to carry over the pairing from the old to the new antenna. It was a while ago so i don't remember the details, but it wasn't too complicated.

Replaced a SD card with it in my Odroid N2+. No more issues with Home Assistant.

Great product

Great product so far

It does what it's supposed to do

This is a great product! I have to get more familiar with it, but overall it’s all good.

I migrated from another Z Wave 700 series stick, and the ZWA-2 offers much stronger wireless signal - basically all of my devices in my 1500 sq ft townhouse now connect directly to the controller. The migration process using Home Assistant is shockingly pain free, I spent far more time adjusting the physical positioning of the (larger than you think) antenna.

Used on a device with same SOC as an Orange Pi Pro.

The add-ons and commitment to basically get all possible hardware going are well received. I'm running a Thread network and have sensors and lighting from various vendors that work seamlessly. Thanks. Home Assistant Team!

Purchased Home Assistant Bundles - ODROID-M1 8GB/16GB-uSD/256GB-NVMe Addict+ / US 120V/60Hz, as an upgrade from Samsung Smartthings. It has been the most stable platform. Completely solid. I recommend.

Works as expected. Great battery life. Sensitivity is great; I often test it by putting a wetted finger across two of the electrodes.

Very reliable hardware and core software.

Great kit, great company to work with
