Monoprice 6-zone Audio amp items, sitemap & rules

That is a great price for it (I paid $550 for mine in 2014). They may be lowering the price since it’s an older product now, so I don’t know if this is the lowest it’s been or not.

Overall, I’m very happy with it - I use it with a Chromecast Audio as pretty much the only input. Combined it with their in wall speakers and I get quality audio al over the house (using 4 of the 6 zones).

Btw, hopefully their QA got better, but first two amps they sent me didn’t even turn on - third one is solid. Monoprice customer support was top notch though, expedited shipping on the two replacement amps. They let me keep one of the bad ones, so I have spare parts I guess :slight_smile:)

I’ve had mine for about 4 years and it’s been working great. I am controlling 6 zones and have 4 different sources. The only issue I had in the past was integration with my automation system and general control over my network and OH (along with Global Cache iTach Flex) solved that problem for me.

Also note this amp is also sold as a Factor Electronics V-66.

I have found the Factor Electronics manual was better in some areas than the Monoprice version.

Another helpful app I found:

The app works great but doesnt always play nice with my OH rules.

Thanks for the feedback and tips! I ordered one and am looking forward to putting it to use!

Thanks for sharing this wonderful information.

First, thank you all for sharing!
It sure saved me a day or two when trying to get my two Dayton DAX66 up and running with openHAB.
The communication is done with a cheap RS232<->USB adapter on a Linux system.
At first glance everything seemed to work with a single unit but further testing showed issues especially with all the sleeps in the rules. After a few tries I understood that a quick fix wasn’t going to work. So I ended up rewriting all the rules with the previous posted contribution as a base.

First of all. This version will not be my final, just a good enough version for now. There is for sure some more tweaks I would like to do but time is up for now :).

Here is a list of the main issue fix:

  1. To keep the user UI feedback experience at an acceptable level the zone states will not be updated until no input has been given during 1 second.
  2. Issues with the math and integer rounding at dimmer value calculation caused some item values getting stuck.
  3. The rules would grow way too much if support for slaves would be added.

Except for improving timing/sleep issues I also added some new features:

  1. The rules can now fully handle both the Master and any Slaves that may be connected.
  2. openHAB can now detect when master unit is powered ON and will automatically start to update all states.
  3. Three new status items that shows which units that is alive (answering)
  4. The stereo balance gauge is made of two dimmers that is synchronized. (Note: You can still use only one if you want to. It just felt a bit awkward for me with a single gauge for this setting.)

And a TODO list:

  1. The Dimmer calculation rule is quite intact. That part can surely be improved.
  2. Sorry @rlkoshak, I didn’t add a Gate Keeper as sophisticated as your one in your super pattern article.
  3. In order to make the rules significantly shorter I had to fiddle with the Item names to fit a get-item-by-name solution. Don’t know right now if this is a really terrible solution.

It’s been years since I did anything with openHAB so some of my ideas are probably quite terrible but I haven’t noticed anything and it is working smoothly except for an issue with the Google Home binding that is mentioned here

My units are of the type Dayton Audio DAX66 but other identical brands are:

  • Monoprice 10761/MPR-SG6Z
  • Factor Electronics V66
  • McLelland MAP-1200HD
  • Omnitronic MCS-1250

Items (with Master + Slave 1)
Note: All “Audio_Zones_Dax66Amp” strings can be replaced. I think the last underscore in each item name must be kept due to dependency in a rule.

Hey. I am hoping you guys might be able to give me some guidance. I am new to openHAB, coming from Home Assistant.

I am having issues with my Monoprice Amp. I am still learning how to configure everything but I got my Ecobee items, sitemap, and rules working correctly.

I am using a usb to serial device that previously working with Home Assistant. I know the OS see’s the device but not sure how I know if openHAB is seeing it correctly.
“Bus 001 Device 004: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port”

I copied the items, rules, and sitemap from the 1st post here. The rules isn’t working for me but the other load just fine. Maybe it is seeing it and my only problem is I need to fix my rules?

“2019-01-09 18:52:27.435 [INFO ] [el.core.internal.ModelRepositoryImpl] - Loading model ‘monoprice.items’”
“2019-01-09 18:52:46.845 [INFO ] [el.core.internal.ModelRepositoryImpl] - Loading model ‘monoprice.sitemap’”

then I get errors with he rules.
“Error during the execution of startup rule ‘MonoPrice Status on command change’: No match found”
“Rule ‘MonoPrice Status on command change’: No match found” and so on.


What you’re seeing is just poor error-handling on my part :slight_smile: - not an actual error with your rules. Basically, when you created all the items, the String item that contains the message going to/coming from the amp is empty, and the rule that parses it errors out on the Regex pattern match. I haven’t had a chance to try @tony_alpskog 's rewrite above yet, but his rules do a better job of error-checking.

Do any of the switches on your sitemap work to control the amp zones? If not, you’ll need to make sure that the String AudioMTX is actually being populated with your commands, and it’s getting responses from the amp (basically, troubleshoot the serial connection to the amp).

Thanks for the reply!

No, so far I haven’t gotten the switches to do anything with the sitemap. I wasn’t sure if it was because the error in the rules (Like I said, I’m new and still learning everything.)

I will take a deeper look. thanks!

I’ve adapted your streamlined version of the rule to use my Globalcache iTach Flex (serial over network) adapter.

I must say it was a bit of a learning curve for me since OH and coding is a hobby for me. I learned a lot about how your (and any) lambda works, although it’s still a little mysterious to me.

Have made any updates to what you posted?

No updates. The reason for the improvement was that I had bought one unit on discount and I wanted to know the limits of the interface before buying a second one. So I just made the whole thing on a “good enough level” to fulfill my requirements. Got the units but they are not installed yet. I will probably continue the work when I’ve got the whole thing installed. No date so far for that :). The test sitemap is a quite crappy hack but I could add it if someone wants it.

Thanks, Tony! I appreciate your contribution. I bought a second unit over the holidays and your code performed well detecting both. The only “issue” i’ve had is the refresh doesn’t seem to work on my system, but all the other functions work.


It’s still my first stab, and it does work. I need to do some work to make it more robust though.

Woohoo, love it! I was actually going to suggest to @swamiller and @tony_alpskog if we should convert this to a dedicated binding, given that it seems to be gaining users (and supports other amps, as well)…Looking forward to trying it out!

While I want you to get excited that it is coming, don’t get too excited. Getting my whole home audio system fully running is pretty far down my list. I’ve been focusing on improving the HomeKit service first (adding support for lots more accessory types, and being more reliable), but I need to get a big jump on it - right now it has an (Apple) limitation of 150 accessories, and I’m already at 130, with lots more smart devices coming soon. So I gotta get that fixed. And then I need basic connections with several more device types. Then I can circle back around to this.

Ah, but the important thing is you got it started! I haven’t had time to even consider writing a dedicated binding for it. The rules I originally wrote have worked just fine for 4+ years, improved by the folks here over time, but I’ve always thought this was a large enough interface to warrant its own binding, especially after @tony_alpskog mentioned that it works for about 5 different manufacturers’ models (and also because a binding should do a better job of refreshing/holding the amp zone states). Maybe we can all collaborate to get it to a point where it’s included in the OH2 snapshots, even if your focus will be elsewhere for the time being. So, thanks for kicking it off (the hard part, I think)!

I fixed the major communications issues. Once I get it running, it seems to work just fine now.


Thank you for the information you shared, I’m trying to get price of Factor X-66 but there is nothing on the site neither on Amazon. could you share where did you got pricing?

thank you!

@AlejandroG I bought mine directly from The amp is the exact same as the Factor Electronics version. My comment was in regard to the manual. The Factor manual is better than the Monoprice manual.

One note with Monoprice, the prices will fluctuate quite a bit so you may want to watch pricing a bit before you buy.

Thank you @swamiller for your fast response, probably from the coding stand point they are the same but the one you referred has some little but interesting differences I would like to explore while coding an improved UI for it. the problem is they don’t have prices, resellers or dealers so don’t know how to buy. I sent them an email we’ll see if they respond! again great thread! thank you again!
