Fixed bug which was causing an error reading the cooling threshold temperature

Reduced debug log verbosity when updating device state to only show essential details
Removed unnecessary .env dependancy used during initial development but no longer implemented

Added error return statement at platform initialisation

Added error return to initialisation to ensure errors are written to HB log
