"It looks like you haven't set up any Homekit accessories..."
I have been using the HomePods to control my central heating with no problems until now.
It is telling me I can set it up with the Home app but I already had.
I do not see a way to remind Siri that it is connected to my thermostat.
Why has it forgotten and how can I 'remind' it?
(This is fairly important since it is not going to switch the heating off when I leave.)
