Daikin HVAC integration lessons learned

Hi there - thought I might post up some quick lessons learned with my Daikin integration, if it helps same anyone time in future with similar requirements/issues. I have recently moved on to OH3, and decided to take the plunge and move all my config from text files to the UI based config, and moved from sitemaps to OH3 UI. As part of this journey, also got around to extending the items I am controlling on the unit, beyond the basic on/off & temp…

At the same time, I decided to upgrade the Daikin wireless control firmware to the latest version, after all, what could go wrong? :slight_smile: (Yes - I do normally know better than that!!)

First things first, my setup is as follows:

  • 1 * BRP072A42 wifi adaptor in a ‘Standalone’ split-system
  • 3 * BRP072A42 wifi adaptors in a ‘Multi-Zone’ split-system (3 internal units, one external)
  • OpenHAB 3.1.0 (Stable)
  • Daikin Binding (3.1.0)
  • BRP072A42 Firmware version 3.4.3

Note that the 3 way split system has some limitations, which don’t matter whether you are using the remotes, or the OpenHAB binding - They can all be in either Heat or Cool mode, but not different (but a unit can be in “Fan-only” mode whilst others are in heat or cool). The system will pickup the mode from the ‘Master’ indoor unit (Set on the outdoor unit) if there are differences. In my to-do list, I will setup something with groups and/or rules to control this, but for now, just need to use OpenHAB like I would a remote.

So, firstly - The integration issues that arose after moving the config into OpenHAB UI, and upgrading the firmware;

  • After a lot of reading, I had convinced myself that this was related to tokens being required after the firmware upgrade, and went down that rabbit hole for a long time
  • When using the browser to test, I would get an error message from the adapter such as: Access to dkac-lvng.local was denied You don’t have authorization to view this page
  • After lots of wasted time, found (via a browser) that whilst the new firmware would not allow me to browse to the hostname or FQDN (http://dkac-lvng.local/common/basic_info), the IP Address worked fine (http://192.168.xx.xx/common/basic_info)
  • Once I changed the hostname to an IP address in the OpenHAB binding, it also worked just fine
  • It IS a firmware issue within the adapter, NOT a name resolution or OpenHAB Daikin binding issue !!

Moving on from there, I decided to leverage the great work done by @maxmaximax with the Daikin UI widget (see: Daikin Aircon / HVAC ) I had to make a few modifications as follows:

  • Fan speed & swing are not supported by the wifi adapter/heatpump combo’s I have (Nothing to do with OpenHAB binding). I have added some properties to be able to hide these unusable items.
  • Some Operation modes are not supported. I took a shortcut here, and didn’t use properties to control their display - Just removed the other modes leaving the main modes used (heat, cool, fan. dehum)

From there, I have jammed all 4 heatpumps into a swiper card, which allow me to easily move between the widgets, while limiting the screen real-estate used.

Only issue with using the swiper card, is occasionally on the mobile, you can grab the temp ‘circle’ and unintentionally set the room temp to 'Bake" :slight_smile: instead of moving between widgets. Pretty rare, and very happy with the result overall.

Pretty much the same as the orignal posted by @maxmaximax, with the surplus items removed,
and incorporated into the swiper card. Note the outdoor temperature is not showing when the unit is off - A limitation of the heatpump, not the OpenHAB binding. I could modify the widget to hide this item when the unit is off, but bigger things to move onto now !!

Hope this is of use to someone, and thanks to those in the community who originally shared their work, and gave the inspiration/starting point to help get me to this result. As well as the UI widget, this also includes the Daikin Binding author/maintainers - This binding has been rock-solid in my installation since OH2.x (Other than my self-induced ‘external’ issue described above!!). Cheers
