Thermostatsupervisor 1.0.7

Monitor remote thermostats and correct deviations from schedule.

ThermostatSupervisor:

supervisor to detect and correct thermostat deviations

Thermostat & Temperature Monitor Support:

1. Honeywell thermostat through TCC web site (user must configure TCC web site credentials as environment variables).
2. 3M50 thermostat on local net (user must provide local IP address of each 3m50 thermostat zone).
3. SHT31 temperature sensor either locally or remote (user must provide local/remote IP address in environment variables and setup firewall port routing if remote).
4. Mitsubishi ductless thermostat through Kumocloud on remote network (monitoring) or local network (monitoring and control).
5. Blink camera temperature sensors.

errata:

1. Honeywell thermostat support through TCC web site requires 3 minute poll time (or longer). Default for this thermostat is set to 10 minutes.
2. a few other low frequency intermittent issues exist, refer to issues in github repo for details.
3. KumoCloud remote connection currently only supports monitoring, cannot set or revert settings.
4. supervisor_flask_server not currently working on Linux server.

Run the Docker Image:

docker run --rm -it --privileged --env-file 'envfile' 'username'/thermostatsupervisor:'tag' thermostatsupervisor.'module' 'runtime parameters'

• '--rm' removes the docker container when done
  
• '-it' runs in interactive mode so that output is displayed in the console
  
• '--env-file' specifies your env variables from file 'envfile', see below for required env variables
  
• '--privileged' runs in privileged mode, this may be required to avoid PermissionErrors with device objects
  
• 'username' is your DockerHub username
  
• 'tag' is the Docker image tag (e.g. 'develop', 'main', etc.)
  
• 'module' is the module to run, (e.g. 'supervise', 'honeywell', 'kumocloud', etc.).
  
• 'runtime parameters' are supervise runtime parameters as specified below.
  

GitHub repository environment variables required for docker image build (settings / secrets):

• 'DOCKER_USERNAME' is your DockerHub username
  
• 'DOCKER_PASSWORD' is your DockerHub password
  

Execution Information:

debug / diagnostics:

updating environment variables:

• Linux: update file ~/.profile and then "source ~/.profile" to load the file

• docker image: export the env files to a text file and specify during the docker run command
  

Source Code Information:

supervise.py:

This is the main entry point script.
runtime parameters can be specified to override defaults either via single dash named parameters or values in order:

• '-h'= help screen
• argv[1] or '-t'= Thermostat type, currently support "honeywell", "mmm50", "sht31", "kumocloud", "kumolocal" and "blink". Default is "honeywell".
• argv[2] or '-z'= zone, currently support:
  • honeywell = zone 0 only
  • 3m50 = zones [0,1] on local net
  • sht31: 0 = local net, 1 = remote URL
  • kumocloud, kumolocal: [0,1]
  • blink = [0,1,2,3,4,5,6,7,8]
  • emulator = zone 0 only
• argv[3] or '-p'= poll time in seconds (default is thermostat-specific)
• argv[4] or '-c'= re-connect time in seconds (default is thermostat-specific)
• argv[5] or '-d'= tolerance from setpoint allowed in degrees (default is 2 degrees)
• argv[6] or '-m'= target thermostat mode (e.g. OFF_MODE, COOL_MODE, HEAT_MODE, DRY_MODE, etc.), not yet fully functional.
• argv[7] or '-n'= number of measurements (default is infinitity).
  
  command line usage (unnamed): "python -m thermostatsupervisor.supervise <thermostat type> <zone> <poll time> <connection time> <tolerance> <target mode> <measurements>".
  command line usage (named): "python -m thermostatsupervisor.supervise -t <thermostat type> -z <zone> -p <poll time> -c <connection time> -d <tolerance> -m <target mode> -n <measurements>"

supervisor_flask_server.py:

Production data is at root, subfolders provide additional commands:

• /unit: unit test (fabricated) data
• /diag: fault register data
• /clear_diag: clear the fault register
• /enable_heater: enable the internal heater
• /disable_heater: disable the internal heater
