I used the ecolink device for some years until I discovered the Zen55, which I implemented a few weeks ago. The ecolink stopped detecting CO after I changed my interconnected alarm system to a new Kidde model as the old one started to give occasional false alarms. The ecolink was also unable to clear the CO Alarm once triggered with the old Kidde model I was using, it required removing and reading the device from the zwave network.
Zen55 worked perfectly, able to differentiate CO and smoke signals and auto-clears when the alarm condition stops. It requires no batteries.
For Music and streaming, specially for hi-res audio. SACD etc streaming, take a look at lyrion music server. The best solution of the myriad I tried self-hosting. Supports podcasts and audiobooks as well
