This is really good work!
I have just installed two of these amps as master/slave and will be trying your code out.
It would be nice to also see some examples how you have set up the audio sources together with the amps in the UI. What kind of players do you use and how to make a good user interface?
@mrfrenzy
The sitemap code above is the majority of what I have done for an interface. I am using Habpanel for an interface in one of my zones (a bathroom) and I intend on expanding the usage of Habpanel in the remaining zones, as I get time/need.
I currently have all 6 output zones from the amp set up. Currently, I only use 3 inputs/sources. I have a DirectTV STB, and Onkyo and Yamaha receivers. The receivers are completely controllable with currently available OH bindings.
I can control all I have hooked up with the sitemap, although it is very basic.
On my todo list, is setting up the PA functionality of the amp to work with the voice functionality in OH.
Here’s what my sitemap looks like (I haven’t incorporated @swamiller 's code improvements into my setup yet, but you’ll get the idea:
OFF:
ON:
I’ve connected 4 inputs on my amp, but mostly use the Chromecast Audio I have connected to it. I have 4 zones outputting around the house and in my shed.
@swamiller, I’m trying to merge your code changes back into mine (have to use only a single status item for serial connections and remove the hex characters), but I think I’m having a problem getting the mapdb persistence to work (which is making all my commands send to a “null” zone and error out). I haven’t used mapdb persistence until this (still using rrd4j). Can you post your persistence strategy config file? It would be useful for everyone implementing this, I’m sure.
Thanks!
EDIT: Ignore this post, see my response below…
So, after looking over @rlkoshak’s suggestions again, I saw the “triggeringItem” variable he mentioned - what a wonderful, long-overdue addition to the rules engine!!! 
I removed the mapdb persistence from your rules, @swamiller, and edited my top post to add the serial-based implementation of your changes.
Thanks again for your hard work improving my original code!
You already have examples code here to consolidate a lot of this code. Note, you can consolidate even more if you were to upgrade to the 2.3 snapshot and use Features for Rules that work with Groups. I’m not recommending that, but be aware there are changes coming in 2.3 that will make rules like this even easier.
rule "Process Update"
when
Item MonoPrice_Status_G3 received update or
Item MonoPrice_Status_G4 received update or
Item MonoPrice_Status_G6 received update or
Item MonoPrice_Status_G7 received update or
Item MonoPrice_Status_G8 received update or
Item MonoPrice_Status_G9 received update or
Item MonoPrice_Status_G10 received update
then
val num = MonoPrice_Status_G1.state as Number
val type = triggeringItem.name.split("_").get(2)
switch(type){
case "G3": postUpdate("MonoPrice_Z"+num+"_Power", if(triggeringItem.state == "01") "ON" else "OFF")
case "G4": postUpdate("MonoPrice_Z"+num+"_Mute", if(triggeringItem.state == "01") "ON" else "OFF")
case "G6": {
val vol = (triggeringItem.state as Number) / 38 * 100
postUpdate("MonoPrice_Z"+num+"_Volume", vol.toString)
}
case "G7": {
val tre = (triggeringItem.state as Number) / 14 * 100
postUpdate("MonoPrice_Z"+num+"_Treble", tre.toString)
}
case "G8": {
val bas = (triggeringItem.state as Number) / 14 * 100
postUpdate("MonoPrice_Z"+num+"_Bass", bas.toString)
}
case "G9": {
val bal = (triggeringItem.state as Numnber) / 20 * 100
postUpdate("MonoPrice_Z"+num+"_Balance", bal.toString)
}
case "G10": {
postUpdate("MonoPrice_Z"+num+"_Source", triggeringItems.toString)
}
}
end
You can collapse your switch statements in your zone rules to
val znum = triggeringItem.name.split("_").get(1)
val zone = znum.substring(string.length() - 1)
For the treble rule you just need to add the line:
val tone_z = zone+"TR"
Even if there were not these String parsing shortcuts, you could use a lambda to consolidate the switch statements
These suggestions should drop your LOC by a third or so. No arrays necessary.
@rlkoshak, VERY COOL!! Thanks for the heads up, that Member Of group handler will do wonders for my rules, especially the metric crap-ton of JSON rules in my MQTT LED strip implementation ( NodeMCU MQTT LED Strip Controller Build & Config How-To Videos ). I could already improve that code tenfold with triggeringItem, but I’ll wait until 2.3 is officially out and then do it all in one shot.
BTW, the post you replied to is ~2.5 years old, back when I was just starting my adventure with OH
Somehow I got mixed up.
At least pointing out the group triggers was useful.
This amp is currently on sale. I’m wondering if this is truly a sale or if it’s just been marked down as it’s a few years old; has anyone been keeping track?
For those who own it: are you overall happy? I’m thinking about picking one up for my new house, though I haven’t purchased the home yet. I’m wary to pick up yet another piece of equipment to move, but the sale price is compelling.
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 )
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.
https://www.mcssl.com/store/factorelectronics/001v-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:
Except for improving timing/sleep issues I also added some new features:
And a TODO list:
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 https://community.openhab.org/t/help-with-a-few-item-warnings-oh-2-3/45832
My units are of the type Dayton Audio DAX66 but other identical brands are:
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.
Thanks.
What you’re seeing is just poor error-handling on my part 
- 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.
