AC On/Off Control Via CBus

Hi All,

Installed my coolinkhub and coolplug on my Mitsubishi Heavy Industries ducted A/C, got it working on there app remotely. Just need to somehow connect this RS232 to my Cbus network. Jaycar wants $190 for a serial to Ethernet converter, don't really want to spend that considering I ordered the new Wiser Automation unit last week for $1300 big ones. Can't wait to get this all working together on the Wiser.

Regards Matt

 

Can't use Ethernet on the CoolLink?

 

The Ethernet is currently hooked up to my router, on the older Coolinkhubs they had an RJ11 Interface Jack and that has been replaced with the 12-24v power supply jack. The way the manual says to connect to Home Automation is via the RS232 Plug.

I am however willing to plug the Ethernet into my Cbus network to give it ago. I am still waiting on Djaggar to send me some Logic code for my Cbus as I wouldn't have the slightest idea on how to get them talking.

 

No don't do that.... You might blow up the CooLink.

Your Wiser will need to talk to the CooLink via ethernet. i.e.. both plugged into your router.

 

Yes the serial API is exactly the same on Ethernet/TCP.

 

Hello Matthew
Dave's Coolmaster files are here http://www.cbusforums.com/forums/showthread.php?t=15957
edit Sorry I just noticed you might need a modified version for the Coollink.

Can you post the exact model of your Coolmaster device.
The first step should be for you to set up the Coolmaster independent of CBus.
Read the instructions.
Send some commands to it with telnet on your PC to check it is all working.

 

My code runs on anything with a Pascal Logic engine i.e. not the new LUA logic engine on the SHAC/NAC ... but I'm happy to port it if there is demand ... but I don't have one of the new controllers so I'd need to borrow one ...

I haven't released the Coolmaster.Net code here purely because the guy I first wrote it for never came back to me if it was working robustly (he just said it was all good and then fell off the face of the planet), so I'm not 100% sure it is at full release status ... once someone confirms it's rock solid I'll do another drop in the Logic Code Examples thread ... I'm being pretty picky, it's unlikely there is much wrong with it (if anything) as it is very similar to the original code.

Those that have sent me their email address by PM should have the latest version (v2.4) in their InBox

 

@djaggar
I think it is worth to mention your pascal code for Coolmaster is still working great.
After all these years.
Right now I am looking for someone to write a Homebridge plugin for Coolmaster and a bit like 10 years ago I realise that might not be me.
Any tips?
I'm not even sure where to start.
I did mention it to Igor.
A bridge device for Coolmaster interface to Apple Home would be a handy gadget.

 

Hey DarylMC,
Ended up calling Daikin as you suggested and they were able to help me programme the daikin wall controller to use the return air sensor and use the touch screen as the on / off. Worked a treat and really simple fix, thanks heaps for your guidance was a real life saver.
Cheers!
