Two fixes:
- New logic for set_temperature that conforms to new service definition.
Now it sets the mode (heat, etc.) if provided, and has better input
checking. - Better behavior when one or all units are unreachable.
If no units are reachable at startup after 10 tries, it gives up. This behavior
is designed to accommodate users who power down their units seasonally.
If a unit that was properly set up becomes unreachable, it will retry only
once (instead of for each attribute) on the next update. Such units will show
as "unavailable" in HA and will reappear if they become reachable again.
Update to pykumo 0.1.10 for #2 above.
