Installation on original raspberry pi b

I have several 3 year old rpi b’s lying around. Can I install HA on one of them? Is there any “gotcha’s” I should be prepaired for using one of them?

Yes you can use them, I have HA running on an original model B. Loading the webui may be slower than a newer Pi due to processor speed differences, but other than that they run the same version of linux and same version of home assistant.

Awesome. Thank you

I just did an install on the original B just last night. It takes a LONG time, about 3-4 hours for me. But seems to work just fine afterwards.
