Use inlet temperature sensor as current_temperature state attribute for the water heater, for easier reference/visibility in HA.

(Currently tested to be working well in my install.)

Shouldn't the temperature of interest be the outlet temperature?

I would have thought so too, but I think the default naming of these sensors are mistranslated (or something to that effect).

The 'outlet' sensor has remained at -50C at all times - nonsensical and uninformative.
The 'inlet' sensor matches the current temperature reported in the Tuya app, and sensibly increases when the heater is running, decreases over time and with hot water use, etc. So I am quite confident this is the correct information to use for current temperature.

An Aquatech Dynamic/X8 branded device appears to be compatible, but reports
the water temperature in dp 16, which was not present on the original
Hydrotherm branded device (it may in fact be gen 7). The inlet temperature
is reported as the cold water temperature at the inlet, as expected, and not
the hot water temperature as PR #1686 observed.  Both devices report outlet
temperature as -50, so that appears to be unused.

To handle these together, an optional dp 16 was added as the
current_temperature, which redirects to inlet_temperature if it is missing.
