A sincere thank you to @fredrike and everyone else who has contributed toward getting the SkyFi (BRP15A61) integration working 
I’ve been running some very spaghetti-like node-red to automate my Daikin SkyFi system for a few years, and am now working to convert this to Home Assistant.
The most useful reference for SkiFi commands that I have found is this one; https://github.com/pabloNZ/DaikinSkyFiNZ/blob/826ad0f82e6c768bfe23bf695bcaeac85754a138/SkyFi%20http.txt , which will refer to below. I have found a few issues with this integration as follows:
-
On these systems, the “auto” fan mode is in addition to the fan speed, not an alturnate to the fan speed (lines 19 to 32 of the link refers). In my node-red spaghetti when I send power on or off (/set.cgi?pass=XXXXX&p=1 or 0), the fan auto setting is retained at the previous state. When I use this integration to power off and then power on, fan auto is always set off. I notice that when my air con is running at “MED/AUTO” the reported state on the States page is “fan_mode: Medium”, which isn’t completely right. Fan auto state is idenitfyable from the “fanflags” attribute from the /ac.cgi or /set.cgi response.
-
Only the first two of my three zones have been recognised (lines 72 to 85). The output of my /zones.cgi?pass=XXXXX is “nz=3&zone1=Lounge&zone2=Guest%20Room&zone3=Spare%20Room”, but a switch has not been created for the last zone. I’m not sure if there is a way to refresh the zone detection?
-
The zone switches always show “off”, even with the zone on. When I toggle the zone switch on, it reverts to off within a few seconds. The log details are as follows:

- My logs are filled with updates failing or taking too long. I understand the connectivity of these units is flakey despite a decent signal strength, indeed a lot of my node-red spaghetti involves catching errors or re-sending if the state fails to change. In my experimentation I found the polling interval sweet-spot to be 20 seconds; more frequently and the device gets overloaded, less frequently and it seems to go to sleep. It definately cannot queue commands.
I’m very new to Home Assistant, so will not be surprised if there is something I have missed at my end. Now that I have this up and running, I would be pleased to do what I can to help test and troubleshoot to get this integration working as best we can.
