Integrating CCU1 into a Modern Smart Home Setup

Hello everyone, I recently upgraded to CCU2 and now I’m wondering if there’s a meaningful way to integrate my old CCU1 into my smart home setup. I’ve heard that some users have managed to repurpose their CCU1 for specific tasks, but I’m not entirely sure how to go about it. Would it be possible to use CCU1 for certain automation rules or perhaps as a backup system? I’m also considering selling it on eBay, but I thought I’d ask the community first to see if there are creative solutions I might have missed. Any insights or experiences would be greatly appreciated! :blush:
