Hi again
This may be a question more appropiate for the Home Assistant forum, but they´re not answering me so far 
I´m trying to install Home Assistant into my Omega2+. I managed to use a 2GB SD card as external storage, since the packages are too big to fit the chip memory.
First, I switched to the LEDE repos and installed python3, python3-dev and pip3 without problems. Then I had to upgrade setuptools manually before installing the homessistant package to avoid errors. So far, everything looks OK.
By the way, I didn´t use virtualenv as the HA documentation recommends because I couldn´t find a way to create another user (no useradd or something similar?). So I run the service as root.
The problem starts when I run th service for the first time. Home Assistant uses pip3 to install even more dependencies and I get an error when it tries to install SQLAlchemy 1.1.5.
INFO:homeassistant.util.package:Attempting install of sqlalchemy==1.1.5

This renders the recorder module offline.
I stopped the service and tried to install SQLAlchemy manually:

It seems it fails attempting to install record, so...

Then I gave it a try to ExtensionClass:

I´m puzzled. I thought I could avoid the out of memory by installing the dependencies in advance but I got a totally different error. Is it possible that these modules can´t be installed because I don´t have a c compiler installed? I have more experience with Java than Python.
If I create a swap file and run hass I get an Out of Disk Space error instead of an Out of Memory. Any other ideas to try?
Thanks in advance.
