Another Annex4 driver user for several years.  I have 4 different model LG's and all have worked perfectly for several years - 1 is an OLED.

I'm in my 7th year with Control4.  I use it to control AV, lighting, hurricane shades, security, garage doors, ceiling fans, fireplace and HVAC.  I didn't go through a home automation selection process because C4/dealer is who the builder worked with the most and recommended.  And this is my first experience in home automation.  I guess I got pretty lucky because we love the system (including my non-technical wife).  The dealer also did the network, security system w/cameras (and central vac).  We've kept it up to date and added functionality as we've gone along.  Here's a few things that may help:
If you are into technical DIY, you really need to understand the dealer model before going C4.  I am into technical DIY, but I wouldn't want to be without a dealer; the breadth and depth of the home automation space is just too wide and deep for me to want to "go it alone".  Yes, dealers can only do certain work (i.e. you cannot) and get paid to do it, but there is an ROI because of their knowledge and experience.  But C4 also allows you to do a lot on your own too. Get a detail install plan from your dealer prior to construction start and spend time understanding it before approving.  Our dealer used the house CAD drawings to produce a network/security/HVAC plan, AV plan, lighting plan. etc.  I learned a lot about the system through review and discussion of the drawings with the dealer.  And neither I nor my dealer had any surprises! We spent time on planning the rack space - making sure we had adequate space (we moved a wall a couple of feet pre-build), HVAC supply (we needed an additional air duct run added to the HVAC plan) and dedicated circuit to the rack (a new circuit added to the electrical build plan). If you want great integration to C4, you need to select components that have great C4 integration capabilities already built.  C4 has a very wide range of robust product integrations, but it is impossible for anyone to integrate well with everything.  You basically find you have a new requirement when selecting a TV, AV receiver, HVAC system, etc. etc. etc. - how good is the C4 integration. This forum has great people that know what they are doing and want to help.  I'm really happy I found it early on and have received great help.  The folks on here have been a great supplement to my dealer.  I haven't had a dealer truck-roll in years!  Good for both of us. Good luck with your process and home build.  C4 does a great job and coupled with the right dealer, builder, architect and planning, you will be very happy with your choice!

Thanks, we hope it will be a really useful integration for Control4 users. I can't really speak on behalf of Chamberlain but we reached out a couple of years ago and are thrilled it all paid off in the end!

@IntrinsicGroup This is wonderful news and very good to hear.  I started out with the old MyQ driver and had to implement relays and contact sensors once that solution stopped working.  I know folks are worried about the company and potential longevity of the solution - and I think it's very positive that this is a revenue producing solution for Chamberlain and developed with their cooperation.  I'm very curious to hear your take on why you think Chamberlain now wants to do this?  Did they reach out to you, or did you propose to them?
However it occurred, great job and good luck with the driver!

Happy Christmas everyone.
To all those who celebrate Christmas, I trust that this Christmas will be a meaningful one for you and your families as we remember the reason for the celebration,  God bless.
Thanks to everyone on this forum for your input and online friendship over this last year as we have shared the passion of home automation and, particularly, everything that Control4 can do.
May 2024 be a great year for you all.

2nd the recommendation to go IP.  I changed about 3 weeks ago because of continual issues with IR - basically specific button pushes that either wouldn't work at all, would only work sometimes, or would be an unintended result (i.e. in the guide, scroll right, scroll right, then the next press to scroll right moves forward a day).  I wish I would have converted years ago.  One unexpected result was that halo voice integration with Xfinity worked right out of the box!  No additional steps.
I worked over months several different times and several hours of work each time to move the IR bud to the "golden" spot.  Never found it.
I do have 3 Xfinity boxes in the house and one of the reasons holding me back were the 2 "child" boxes.  I ended up just getting 3 parent boxes - the monthly cost is the exact same.
If you need someone to install the driver, I recommend Mitch @msgreenf - he did mine and it was perfect as usual!
*edit - I see you are referring to a client so you wouldn't need Mitch's help, but I'm leaving that in for others that view.

I bit the bullet a long time ago when MyQ integration first failed and implemented a relay, contact sensor and garage door experience button on both doors.  Works every time and is available local and remote right from the C4 app. No cloud, no delay, etc. etc.  I wish I would have gone with that solution from the beginning when my C4 system was first installed during the house build.  I did the design and all hardware and physical connections myself from reading posts on this site.  Ari supplied the C4 I/O device; got some help with driver install and programming from Mitch.

This is true for the main box. It is a 4K, IP addressable DVR. For a secondary box you would want the Xi6, also 4K and IP addressable. The local stores may or may not carry them (they don't in my city). But the local store is still the best place to oder. Xfinity's online support is the absolute worst for anything that doesn't have a script. It took me 4 contacts, including the last at the store, to get the equipment I needed properly ordered.

That box doesn’t get voice or IP control.
I have multiple IP drivers, using voice, with no problem.  They are the XG1V4 4K DVR boxes. 

As Alan mentioned, if the system is not receiving from the app the "stop ramping up command" due to a network issue, then modding the driver isn't going to solve anything.
Your experience where volume down was sent, and then it did a volume up, suggest a delay or it was still processing the original volume up command.
When the HC800 existed, were the IR plugged into it, or still the IO extender? Might try moving it to the Core5 directly, one less hop.
The only other thing to suggest (other than network) is to add a 1 sec or 1.5 sec timer to programming. When volume up start received, start timer, timer expires send volume up stop. Max volume up ramp would be limited to timer length.

He is fixed. H is system was set up with the TV via IP, not SDDP. Change it to SDDP and everything works

Huh - a remote with no physical buttons.  I wonder what the difference is between that and an iPhone?  I have a new regular Halo and really like it. I’ve been thinking about buying a touch, but I’m not sure if there is enough room between the regular halo and the iPhone app to make enough difference.

In Florida, we call it "reclaimed water", and it's not potable.  But it is cheap!  The water is runoff from the rain and is stored all over in connected ponds, etc.  Pretty extensive system.

I doubt I'd use it much either, but I'm not using HDMI out of the core and the leaf matrix has plenty of pots, as it's hardly used these days either - might try to get it running now that I know its still available.

Didn't used to be.  Louisville water co - making the Ohio river's finest!  I can remember paying my ~$25 water bill that came ever other month - it cost too much to send the bill every month for the little collected.  Then we moved away in 1994 to Nashville and got "water bill shock" (along with real estate shock, etc.) right away.  But I digress 

I upgraded from the CA-16AMP to Triad to get HD sound quality.  I had the CA-16AMP installed for 2+ years and it worked great with great sound.  I've had the Triad matrix and amp installed for 4 years and it's been fantastic too.  Along with the Triads, I upgraded speakers in 3 rooms.  The sound from the Triad is excellent; I wish I would have started there - I would have saved some money!  Don't get me wrong, I wasn't unhappy with the CA-16AMP - I just wish I would have answered my dealer differently when he asked about what quality sound I wanted during the sales process!

When alarm triggers start timer dontmissthetrain.
when bath light is turned on stop timer.
when timer expires play damnit.mp3

Since there has been no power loss, the only other thing I can think of is making sure you have these 3 LG settings "on" on your TV:
QuickStart+ (that may be why your GET_POWER_STATE returns the value of "on" because QuickStart+ puts the TV in standby mode vs. power off state) LivePlus Mobile TV I had to call my dealer a few weeks ago for one of my LG's where I did a factory reset trying to debug a sound issue and they had me check these 3 settings to restore C4 control.  That fixed it for me - hopefully something here works for you.  I have 4 different model TVs on a variety of WebOS versions, but these settings are on on all of them.  Also, I use the Annex4 driver.
btw - I never fixed the sound issue; I'm assuming that it's a TV issue which is weather induced.  The TV is an "indoor" LG installed outdoors on my lanai, so still under roof cover.  It's over 6 years old and been through 2 hurricanes.  Still has a good picture and we run sound through external speakers - so the sound problem is only an issue for native LG smart apps.
