Stella Z has no thermostat control in new expert interface

[janw]

I just installed a Stella-Z. So far so good. In the `old blue mode', the thermostat is visible and I can
both switch the mode and the setpoint. In the new exper interface though, the thermostat appears
under control/thermostats, but it does not show the current value and does not let me change the
value. This is not vital to me, but I think worth reporting. Raspberry runs v2.0.0.
