I am currently looking at either purchasing the Daikin DCPA01 which exposes MODBUS, or using the controller from Arnold.
For the latter we would need to help with reverse engineering some elements of the protocol.
(It is already working for heat pumps, and single units)
Has anyone successfully made this work with modern Daikin Air cons? I have been talking to their tech supports and they given me docs to help with controlling via ModBus. I have no idea how to make this work.
I did see this example of modbus working and not sure if we can do something similar - Setup FoxESS and Home Assistant using RS485/Modbus - YouTube
Hello braverynew
Please, can you help me with the image for raspberry? I’ve been trying to get the condinionter air control of 7 daikini teams working and in my country I can’t find support, thanks in advance
Hello
Pls source code for rraspberry ? Clone image ?
I have a very old version of the controller, I’m trying to upgrade it and get the website to work directly with Home Assistant. Hit me up if anyone wants to actively work on this. Not sure how I missed the email notifications.
If anyone has worked with WebSockets on HA it’d be incredibly helpful.
Yeah the image for Raspberry Pi and I have been going through the website code which can be found at /var/www/html. It’s a standard Apache server with a Ruby backend.
I’ve built an integration for the Daikin DTA116A51 DIII-Net/Modbus Adapter.
Waiting for it to be added to HACS.
Should be able to manually add the repo for the moment.

great work!!!
I ended up buying their BACNET module when I saw one come up second hand
Thanks for the integration.
I noticed that the Daikin data is being fetched every 10 seconds. Could you clarify if this polling is counted towards the 7,000 control commands per indoor unit per year limitation?
Is it possible to integrate a third-party temperature sensor with the climate card? If I’m not mistaken, the temperature sensor is located in the control panel, but all my control panels are hidden away in a cabinet. Hence, the temperature readings won’t be accurate for my case.
My interpretation of the documentation was that the 7000 control commands was for writes, not reads. If not, my system must be on its last legs at over 500k reads since I implemented it.
I’m not sure how you’d integrate an external thermostat into the climate entity as it needs to be provided in the one integration. There may be 3rd party control that can integrate separate entities into something like the climate interface. I’ve broken out most of the functions into individual entries as well to make them easier to access by other controls.
