Re: Flow switch recommendations - and integration to HA server

["noel" <noel@xxxxxxxxxxxxxxxxx>]

Hi all,=20
Reviving this one as I'm finally looking to buy one, due to speak with the
=
company this morning re the flow restrictions, one further question though.

I'd like to use the flow switch to do two things:

1 - Turn on my mirror heat pad

2 - trigger an increase in volume through my HA server (music needs to be
l=
ouder when showers on), to do this I'll need to get something that can
brin=
g inputs into the server unless I can do something clever wirelessly with
x=
10 or similar?

How would I go about doing both of these from the same flow switch, and
any=
thoughts on how I could achieve the second one?

Thanks

Noel

that's not =
enough for a good domestic shower fed from a combi boiler?? Looking to
