Having a strange problem trying to use C4 with Heatmiser. Anytime I try to increase my radiator temperature via C4 OR the Heatmiser app, the temp keeps falling back to the scheduled.  

Does anyone know how C4 talks to Heatmiser for home thermostat control? I’m struggling to understand the two way process between C4 and HM. Does C4 "pull" from HM? 
 

Hi all

Does anyone know how C4 talks to Heatmiser for home thermostat control? I’m trying to understand the two way process between C4 and HM. 

Eg: If I set the C4 thermostat degrees and schedule, does it “override” what is set in the Heatmiser app? Or will the C4 “pull” the data from HM? 
 

Or, must I set both the schedule and the degrees for the thermostat in both HM and also in C4? 
 

Thanks. 

Amp replaced. All working OK now. No idea what the fault was, it was a brand new amp which packed up after 6 months of general home use. New one now installed and working. 

Moved ATV from rack, fitted behind the tv. 4K HDR (and Dolby Vision) works brilliantly! Image is ultra crisp, razor sharp. 

Pleased for now.  

Thanks all. I personally love the Apple UI, and the family are all comfortable using it. Android OS is ok, but I find the Apple to be faster to use and far easier to operate. 

Prior to starting this thread, I was not aware the HDR 4K is only supported unto 30Hz. I am glad I'm not the only one who feels this pain!

Rather than splash out on a new AV receiver, I will do what most have suggested - connect the ATV 4K directly into the OLED TV, eliminating the matrix. Hopefully this will work without too many glitches. Its a big shame though, as that means moving the ATV box out of the current rack, fitting it somewhere nearer the tv - hopefully out of sight - and finding power and ethernet and HDMI cables to install neatly etc. Its just a hassle! 

EDIT - Can the Control4 SR260 remote still control and talk to the Apple TV, IF the ATV is not connected via ethernet cable - i.e. just Wifi? 

Also, if the Apple TV 4K is connected to the TV only, if I play Spotify thru the Apple TV, can I still output the music to the Control4 ceiling speakers? 

Thank you. However, my requirements are much simpler than that. I just need 4K HDR video from my Apple TV. I do not need any different audio options. 

Lots of stuff - such as Apple TV+, NBA, and Disney.

Thanks all.

I simply wanted one TV in the main family room to support the full 4K HDR experience. It seems as though now I might have to invest in a separate AV receiver in order to achieve this.  

Could I connect my Apple TV 4K directly into my TV via HDMI, enabling the 4K HDR content to work absolutely fine? If such is the case, having invested in C4, it is highly frustrating to learn it has this limitation....unless I am missing something. 

Thanks for the link, will check it out and get back to you.

Try 4K HDR at 30hz

Whilst that resolution does work, the image when playing back content is visibly a lot darker, naturally. 

The optimal setting I've found is 1080p HDR 60Hz which although works great, it rather defeats the object of having a 4K OLED screen with 4K Apple TV, if Control4 doesn't support it. 

If that is definitively the case, I find that rather disappointing. Do you know if there are any plans for this to be supported in a future release?  

Thank you for all the replies so far, very helpful from all.

The Control4 matrix doesn't support 4K HDR at 60hz unfortunately.

Really?! Very surprised by that. What about HDR @ 50hz? 

That was my understanding, too. 

For the avoidance of doubt - my Apple TV4K IS  - most certainly - connected to the Matrix. The Sony OLED TV also supports 4K.

However, when I try to switch the Apple TV 4K to HDR 60 or 50 HZ (in the ATV menu under 'Settings'), it does not work and switches back to 1080.

Hence my question - does C4 need something doing in order to support the HDR output? What is "zone lock" - can I do this, or is it a dealer configuration?  

Apologies if my question was not clear. 

EA5 Controller

Apple TV 4K

Sony AG8 OLED 

Matrix Switch UHD 6x6 

I have an EA5 controller and C4 Matrix. 

The Apple TV is connected via HDMI into C4; it is NOT connected directly to the television.  

I have a Sony AG8 OLED television, which supports a HDMI signal of 24, 50, and 60 Hz. However, I cannot switch my Apple TV 4K to the HDR setting for 50 or 60 Hz. It does, however, seem to work at 24Hz, but the image looks quite poor, as expected. 

Does C4 allow the signal from the Apple TV 4K to output at the higher resolution? I'm certain this used to work, but ever since my last system reboot, the Apple TV 4K no longer outputs at the higher resolution on the Sony TV. Any suggestions?  

Quick Update: the Dealer came out to my house, but was unable to fix the Amp. This has now been processed via RMA, awaiting delivery of replacement. Will keep you posted. Thanks all.

Not extreme at all.  You have a problem.  Tried reboots to no avail.

Only other option is to get it replaced under warranty.

 

Agreed. Thanks for the advice.

Your dealer is handling the issue, correct? Sounds like they are involved. Coming here for more help seems reasonable, but I think most will simple tell you its probably broken if the resets and power cycles didn't work and your dealer is already looking at it.

If the noise came over your speakers without a source on then it sounds like there is a real problem.

I'd suggest that if you want to still mess with it you could work with your dealer and test swapping the input connections and cables. I assume you haven't had the dealer out to the physical location yet.

Thank you. 

Yes - Dealer is handling, just awaiting to hear back from them re: next steps. They are yet to attend site, will keep you guys posted. 

a Return Merchandise Authorization? Seems a little extreme, is there nothing else that can be tried in the meantime? 

Hi all. First time poster here, please excuse me if this has been posted in the past. 

I have an EA5 controller, with Triad PAMPS100 8-Zone Amp. 

A few days ago, I noticed a very 'high pitch' sound from a number of my ceiling speakers. It was a continuous sound, very high frequency. I played some music to all zones, then ended the session and the speakers were fine. Few hours later, the sound came back so after instruction from my dealer, I powered down the Amp as it was getting very late. Unfortunately, since powering the amp back up, I cannot get ANY audio to any of the speakers in any zone. The high pitch sound has also gone. It seems like there is a problem with the Amplifier, but it has been working fine and has not been touched in months. 

My C4 Dealer did a hard-reset yesterday, powering everything down then back up again. Sadly, that has not made any difference as the Amp is still not producing any output. 

Does anyone have any knowledge / experience with this issue please?
