I'm in an even more comical situation. Built a new house a few years ago just when Polisy was coming out. None were available so I bought an ISY. Then ISY stop supporting the latest version of nodeservers on a Raspberry Pi, so I bought a Polisy and installed some nodeservers (that would have run on the the RPi) with intention of moving the ISY to Polisy and updating the the new nodeserver version a short time later. Unfortunately a couple of the nodeservers I needed wern't yet ported so I never moved. Instead I started using Home Assistant on a Small PC and integrated with the ISY to get the functionality I wanted, with the intention of moving everything once the nodeservers were available.
Well I never did move and found that only two of the five nodeservers were something I needed/used and one of the two I used went away - myQ. So I plan to move the one I use, envisalink, over to Home Assistant and turn off the Polisy. No point in moving to Eisy at this point. Besides it might be superseded before I have time to integrate.
Is there a market for lightly used Polisy's?
