I discovered JetHome Jethub D1 and Jethub H1 Linux automation controller based on respectively Amlogic A113X and S905X SoCs in Linux 5.16 changelog, as both platforms got upstreamed to mainline Linux.
I had never heard of JetHome, a Russian company based in St. Petersburg, nor their products before. Both Jethub D1 & H1 will run either an Armbian-built Ubuntu operating system or Home Assistant Operating System (formerly HassOS), and support Home Assistant (Z2M), Home Assistant (ZHA), and ZIgbee2MQTT. Jethub H1 looks like a TV box with a Zigbee module, while Jethub D1 is a DIN Rail automation controller with plenty of I/Os. Let’s focus on the latter.
JetHub D1 specifications:

There’s a detailed Wiki in English and Russian that shows how to get started using Armbian Ubuntu, Home Assistant, Zigbee2MQTT, and so on. The controller is designed for automation systems that gather sensor data, perform PLC functions in smart home systems, direct load control, and so on.
JetHome recommends the 512MB/8GB model for Zigbee2MQTT “on the go” or Home Assistant in a virtual environment, while the older model with 1GB RAM/16GB flash is suitable for Home Assistant with addon system support.
JetHome JetHub D1 is sold for $57.75 (512MB RAM) and $83.47 (1GB RAM) plus shipping, which seems incredibly inexpensive for this type of hardware. One of the reasons for the low prices is that the company does not provide 3rd party software support (e.g. Home Assistant, Zigbee2MQTT..), so you’d have to solely rely on the information in the Wiki or your own knowledge. If you’re just interested in a Linux-based Zigbee, Wifi, Bluetooth, and Ethernet gateway without I/Os, JetHome JetHub H1 is sold for $51.32.
