Lightwaverf using Hass.io?

Hi,
So I have just entered the world of Home Assistant. I have started with Hass.io on a PI3.

I have a lot of Lightwaverf and also have the link hub. I therefore need to integrate Lightwaverf. I have spent a few days learning Hass.io and researching options on how to control the Lightwaverf. So far I have come up with:

  1. Buy an Rfxcom. I have found a number of people using these for the job.

  2. I have found a post showing a bash script to control the Link hub directly. This doesn’t mean a lot to me, but am I right in thinking that this can’t be used with Hass.io? If I wanted to use this method would I need to switch to using Home Assistant (i.e. not Hass.io)?

Option 2 looks much more complicated (for someone with no experience), but I might be able to to get it working if it is a possibility. I didn’t want to spend the week trying to work out if it even can be done.

Is there another option?

Thanks.
