Description of Change

We find device.endpoints sometimes is disordered, like “ep0, ep5, ep1, ep3, ep4, ep2“. So we plan to sort device endpoints in ASC before judging the device type of equipment,

Summary of Completed Tests

We added Unit Test and tested with real device.

I think a slightly more generic version of this function could be:

local function get_device_type(device)
  local device_type_found = {}
  for _, ep in ipairs(device.endpoints) do
    if ep.device_types ~= nil then
      for _, dt in ipairs(ep.device_types) do
        device_type_found[dt.device_type_id] = true
      end
    end
  end

  for _, id in ipairs({
    RAC_DEVICE_TYPE_ID,
    AP_DEVICE_TYPE_ID,
    THERMOSTAT_DEVICE_TYPE_ID,
    FAN_DEVICE_TYPE_ID,
    WATER_HEATER_DEVICE_TYPE_ID,
    HEAT_PUMP_DEVICE_TYPE_ID
  }) do if device_type_found[id] then return id end end

  return false
end

This ensures that we're not just basing the logic on which device type we see first, but rather the order of "precedence" that we give the device types in the drivers. I tested this and confirmed it works with your test case. Thanks

We also think this is a more generic version and updated PR.
We tested with real device, it works fine, thank you.
