GoldAir Wifi Fan not being detected as a fan

[jwhite]

This is what I have in my logs....

I will try to set the detection by hand and see what I get.

It's quite different from the schema of the fan that is supported. dps: "1": true, "2": "1", "3": "1", "4": "off", "6": "0", "19": "24"

current fan schema: dps: "1": hvac_mode[false=off, true=fan], "2": fan_mode[1-12], "3": preset_mode[normal|nature|sleep], "8":swing_mode[false=off, true=horizontal], "101":display[false=off ,true=on]

DPS 1 and 2 may match, but the others are all different, and the mismatch of 3 at least is likely to cause the code to throw exceptions and the device not to work at all if manually set to fan.

[jwhite]

No, I mean I was hacking the code to work with the new schema. I forked the repo - is anyone available to give me a quick overview of how to use the toolchain to quickly get my code up and running?

I have docker/build container/code/etc. installed already. I need a quick best practices walkthrough.

[make-all]

For development, I just use a VM environment with pytest for running the unit tests. If you look at .github/workflows/tests.yaml, you should get some idea of what is required. For actual runtime testing, I deploy to my raspberry pi actual HA installation (probably not the best practice, but it isn't a mission critical system).

I think the features of your fan are sufficiently different that you would be best creating a new device. Copy the fan directory to a new directory and start from there. You'll need to figure out what each DPS is for, by changing settings on the fan manually and observing the DPS changes. DPS 19 is in the right range to be a current_temperature reading, which isn't supported by the current fan, so look at one of the heater devices to see how that is handled. Once you've figured them all out, remove the things that aren't supported by your fan, and add in the additional features if you want to support them (things like timers probably aren't useful to support, as there is no easy way to use them from HA). Link the new device in to the top level device.py and climate.py by looking for where the fan is being used and do something similar for your new device (I suggest using the model in the name, like the newly added heaters).

Hi @jwhite, apologies for the delay. As it's been summer I've not been paying as much attention to this integration as I should.

Which model of fan do you have? Would you be willing to do some investigation to figure out the DPS schema? I can help you with instructions. If we can figure out the schema I'd be happy to add support to the integration.

@nikrolls The fan is model GPTF390

You can see the fan here [fan]https://www.harveynorman.com.au/goldair-platinum-117cm-tower-fan-with-wifi.html(url)

I don't mind adding it either - as I already forked the repo to do some testing. I am not sure how to disambiguate it from the other devices however, as there is overlap on the schema. The fan is reporting 1,2,3,19 (on, ?, speed, temp).

Getting a key to communicate with it involved decompiling the goldair apk to remove the encryption on the packets and then doing a remote packet capture. So, I do have raw data as well.

Ideas on how to disambiguate?

I mostly got slowed down on setting up a workable toolchain that pushes the code to my instance. What do you use? File copy to network share?

Cheers! -Jeremy

Is the fan only reporting those 4 dps and no others?

The URL has disappeared, but Goldair has a matching GPTF390 (exclusive to Harvey Norman) on their website. According to the manual, there should be control of power, presets, oscillation, speed, and a timer. And it contains a digital thermometer, so presumably the temperature reading is coming back. So I'd expect at least 6 dps.

The detection by checking small numbers of dps gets harder the more devices are added. Maybe check the type as well if you can't find a combination that doesn't exist in other devices.

dps: "1": true, "2": "1", "3": "1", "4": "off", "6": "0", "19": "24"

So 6 dps.

@make-all

[make-all]

OK, sorry, I see you had all that info back at the start. So: 1 = switch (hvac_mode) 2 = ? 3 = speed (fan_mode) [1=low, 2=mid, 3=high?] 4 = ? 6 = ? 19 = current_temperature

I guess the information needed is which of 2,4 and 6 is preset mode, and which is oscillation, and what values those can take. And is it correct that this is a three speed fan, so the range for dps 3 is 1-3?

[make-all]

This looks like it could be the same DPS layout as the Kmart Anko fan with an additional temperature sensor. In that case, I guess DPS 2 would be the presets with '1', '2', '3', '4' for 'normal', 'nature', 'sleep', 'child' (maybe not in that order), DPS 4 would be the oscillation switch, with either 'off' and 'auto' like the Anko fan, or 'off' and 'on', and 6 will be the timer.
