A simple Java app that simulates a Daikin Heat Pump. Its purpose is to play around with ESPAltherma and D-checker.

It works in two different ways, based on theconfig parameter 'mqtt':

• standalone (mqtt = false):
  • read register data from file 'work/data.txt'
  • you can modify this file (do not alter its structure!) and the app will reload it on the fly
• mqtt (mqtt = true):
  • read register data subscribing to MQTT 'espaltherma/log'
  • you can modify the file 'work/spoof.txt' (do not alter its structure!) and the app will reload it on the fly
  • this file overwrites bytes received from MQTT where the file has a value != '--' (it's easier to do than to explain)

The app will calculate CRC on its own, so do not include CRC values in these files. The first line of both files is a header and it is not parsed, so don't modify it.

• import this repo inside your IDE (I use eclipse)
• create the config file 'src/main/resources/config.properties' (copy 'config.default.properties')
• set the parameters with your values
• build and launch (no command-line args required/supported)
• eventually give firewall permission for inbound port 50000
• wait for data, if using mqtt mode
• launch D-checker
• configure options (only the first time)
  • click 'Options'
  • select 'COM port' = 'TCP/IP(WiFi)'
  • set address to '127.0.0.1'
  • fill 'Service office' field with whatever
  • fill 'Responsible person' field with whatever
  • click 'OK'
• click 'Recording'
• add a customer (only the first time)
  • click 'Add new'
  • fill 'Customer id' field with whatever
  • fill 'Customer name' field with whatever
  • click 'Ok'
• double click the customer row you want to use
• click 'New'
• ensure the checkbox 'With BTSC/Wi-Fi' is not ticked
• click 'Altherma'
• wait for detection to end
• select an option for the field 'Data label file'
• click 'Ok'
• select the tab 'Op. All data'
• now, you should see 6 tables of key-value pairs

At this point, you can modify the data/spoof file and you should see the changes reflected into D-checker GUI.
