A Domoticz plugin to control the Smart Temp SMT-775 Inspire Thermostat

WARNING <<<<<<<, the company appears to have made a change to the thermostats software.

When attempting to get the temperature from the thermostat, I just get the message:

I've removed the MAC address and changed the encrypt key in the below example of the output I am receiving:

{"mac":"REMOVED","dev_type":775,"dev_ver":1,"encrypt":"0e9a778a1c16ac00c6355340d596e3ba"}

Attempts to control the thermostat appear to be ignored (I assume it now requires whatever encryption mechanism that appears to have been introduced).

Configuring the plugin:

• "Domoticz Lan IP" is the static IP address you have given your computer that is running Domoticz
• "SMT-775 Lan IP" is the static IP address you have given the SMT-775 either by setting a static IP on the unit or by using the DHCP settings on your router.
• "Number of Zones" is how many seperate air conditioning zones you have (you can find this out by looking in Zones on the SMT-775 physical screen.
• "Temperature Drift" is how far the thermostat should allow the temperature to vary from your set temperature, the default is 1 degree either above or below your setpoint.

It was nessesary to combine the cool and heat setpoints into a single temperature with a "Drift" allowance in order to accomodate home automation appliances such as Amazon Alexa, eg: "Alexa set the thermostat to 22", the plugin takes care of setting the thermostat to heat at 23 degrees and cool at 21 degrees.

Note that Alexa has been tested and I can confirm that it is working nicely in my environment. Note that a seperate Domoticz plugin is required for Alexa support.

Todo list:

• Add zone temperature sensor readings
• Sync Domoticz device status with changes made on the SMT-775 physical screen
