I’m a bit stuck here; any help you can give will be appreciated.
After instal EspHome in Home Assistant I am try to add device Esp32
Hardware Raspberry PI 3+. 1 Mb RAM
I choose “Manual option”
And this is what happens

You would be best posting this in the ESPHome section, but I suspect your issue is lack of memory on pi3b. There is bit of workaround but you are probably putting off the inevitable that your hardware isn’t up to it. Another option is to compile on a separate machine but you lose the convenience of all in one place but it does work.

I ran out of memory on a machine with 2Gb of memory on bigger compiles, I’d aim for 4Gb machine if you want to do a lot of big ESPHome projects.

A kill with a signal 9 usually means the operating system killed the process due to critical levels of resources.
With a RPi3 it is very likely to be due to memory usage.
A RPi3 is only able to run a moderate HA setup with the current releases and many are forced to upgrade as the OS keep growing in memory usage. Running ESPHome on top is really a bit too optimistic.
