Please help:
I have purchased and moved into a new house. The last owners were not the purchasers or installers of the pre-existing wired sound system and do not have the details. The house is 3 stories and 4000m2 in size, there is a very complex lan and wlan nbn enabled tree network that has a server room and cables running throughout. There are 5 wireless routers and the current speakers a visible in spotify via at least 2 different wifi routers. I am looking to transfer the sound system ownership of the new house and merge it with my current (small in comparison) s2 sonos wireless speaker network. The pre-existing speakers are built into the ceiling and are indoor and out door (there are around 15 speakers in 3 rooms). I think the old system is about 5-10 years old and the mounted installed sonos s1 wired speakers might have integrated amps and the system seems to be run via lan network, with inputs via the wifi routers coordinated via a netgear switch in the server room. There is no access to the roof above the speakers and i can not see and independent control hub or amp.

In one of your original ceiling speaker photos there was a light spot suggesting a pilot light. Maybe it was a simple reflection and the speaker is not active.

Did you use your thermal scanner to view inside the ceiling areas shown in the latest batch of photos?

There is no need to post IP addresses or diagnostic conformations here.

ZP100’s are S1 only.

Although it’s messy, working on the assumption that each power circuit serves a relatively small area (no guarantee), you could selectively power down each circuit in an effort to approximate SONOS locations. I did this in one college apartment and discovered a circuit that was not fused!

If there is a 3rd party amplifier, there will be a ZP80, ZP90, or CONNECT on the network. Unless you have a direct view, I doubt that a thermal imager would spot any of these.

Are there any in-wall speaker Volume controls? These may give location hints and can be connection points for wire scanners.

Your dense walls will enhance the precision of a WiFi scan for players.
