...so I did a little digging on the interweb and came up with the following solutions: a) Nest I bought Thessa from the app store which has an apple watch extension and notification centre widget. Works well but does not currently have access to the digital crown. I assume this will come with native apps. b) Sonos A part work around. I installed AirSonos onto a raspberry pi and can now airplay to the sonos speakers from all my iDevices. This means I can remote control the iPhone music app or play music from the watch both to my sonos 1. You can also use Siri! My Sonos speakers are now a lot more usefull all for about £25 and a few leads I had lying around. I'm not sure if I'm allowed to post a "how to" for AirSonos. If Mods say it's ok Ill post one up or you can google Airsonos. I had to mix and match from a couple of guides to get it working but it was quite straight forward. Hope this helps people with their home automation which is going to be the watches "killer app".
