Enhanced SNZB-02 As a Thermostat/ TRVZB Emulation

A thought for Sonoff: There are situations when it would be desirable to have the features of a thermostat in a small simple device like the SNZB-02. Features found in TRVZB (Thermostat Mode: OFF- Manual - Auto, Status: Heating - Keeping, Smart Schedule) to create a virtual TRVZB for controlling other switching devices. A TRVZB without the mechanical drive to a radiator valve. Thank you.
