One of the features of the waterfurnace 0.7 is timingout out stuck
connections on the websocket (which tends to happen after 48 - 96
hours of operation). This requires the homeassistant component to
catch and reconnect under these circumstances. This has turned out to
be pretty robust in preventing stuck sockets over the last month.
Add waterfurnace platform
This adds support for waterfurnace geothermal systems. This is
implemented as a component as there will eventually be some active
control elements. This is not done as a climate platform because
geothermal systems work best when set at a constant temperature as
they are tuned to keep within 0.5 degrees F of a setpoint, and large
temperature shifts are slow and expensive.
This is done in the Data + Sensors model, with the Data component
having a regular update thread. That thread needs to call the read()
function at least every 30 seconds otherwise the underlying websocket
is closed by the server.
