I have been playing with an ODroid HC1 ($40 - $60) for the last 2 days running the beta HassOS distribution for ODroid XU4.
The HC1 has a Samsung Exynos octocore processor and 2GB of DDR3 RAM. It is subjectively quite a bit faster than the Pi 3B+ that I’ve been running. I hope that with a little more work it will be much faster. Benchmarks that I’ve run show it to be around 2X - 4X faster than a Raspberry Pi 3+ on most things as is. By hardware spec it should be more like 7-8x times faster than the Pi.
I installed the beta XU4 build. The basic install was super easy, no different than HassOS on the Pi, I downloaded the release build and then wrote it to an SD Card using etcher. It booted right up and downloaded and installed HassIO 0.86.2.
The standard mechanism of enabling SSH on port 22222 via CONFIG/authorized keys worked fine.
I mounted an old Crucial M4 480GB SSD in the SATA tray and the kernel recognized the drive and I was able to partition the drive with fdisk and created an ext4 filesystem using mkfs.ext4.
The next step is to figure out how to move some or all storage off the microsd card onto the SSD. I’m not sure if this is possible with the current build of HassOS. If I figure out how to do that I will follow up.
If anyone else is running HassOS on ODroid, I would be happy to hear experience or advice.
