I thought I had to setup remote by use of the blue button. Don't know how to control the Heos through Domoticz now. Can't find out how to use this feature possible to explain me a bit more
Indeed the app shows the same ip as I discoverd through scantool

Through a ip network scan I found the IP address of Heos. I added the Heos by filling in this hardware IP field, and now its visible in domoticz /#/hardware with idx23 port 1255. The blue setup button doesn't recognize its being "touched", if there is no <ahref> (html) in the code. :roll: The other ...

Very nice that HEOS also can be used through domoticz! I just added a heos1 in hardware tab and it shows HEOS by DENON and a button setup. This button doesn't function. So I opened the html.appcache file but this starts with 1306 and not 1298. What do I misunderstand?
