Hi there, I have a multiroom system based on Qualcomm Allplay (discontinued) and searching for a motivated Home Assistant integration developer that is willing to migrate the openHAB Integration “AllPlay binding” to a Homeassistant Integration. I’m also willing to pay for that, cause I’m loving my multiroom setup (Asus Clique R100)
