No issues or anything so far with the Unifi devices? That’s good to hear. Do you have any third-party integrations with your Unifi devices, or is it as locked of an ecosystem as I’ve read others say? I don’t think I’d mind taking the plunge, as long as it has good customer service and support.
I’m not very experienced with OpenWRT - how sensitive is it to device changes? If your Barracuda dies tomorrow, do you have to purchase the same brand / model, or could you slap your saved config onto a similar device? Is there some sort of device compatibility to consider?
