Chromecast Polyglot NodeServer

I've added bool value into new version, 0.4.5. See if it fixes anything. I won't be able to test it myself until next week.

xKing · July 20, 2018

Update from the Polyglot store did not work since you apparently mess with server.json so in order to update from the polyglot - I needed to "git checkout ." first.

Anyway - status in programs is fixed

I have the same (or similar) problem with my own "production" polyglot. It functions fine but looses all status labels. Development seems to always work fine but it's only working for short time usually. I'll get to the bottom of it.

I wonder if this could also be related to the incorrect online/offline reporting?

Can you elaborate? I update version and description in server.json. Am I doing something wrong?

Or does polyglot update fail because server.json timestamp is different?

Amazing, whatever you did in 0.4.5 fixed the issue. All chromecast devices are now being reported as "online: true". Chromecast device status is available in conditions to trigger events. Status updates immediately when I trigger something via the ISY.

Is it possible to decrease the polling interval for status updates, or receive status updates automatically (push) from the Chromecast? Right now, it takes several seconds to get a status update from a chromecast device. I plan on using this plugin to control my amplifier power state based on chromecast playstate. A several second delay after playing begins (plus the time it takes for the amp to warm up) is relatively long before the music starts.

Finally, as xKing has said, updating the plugin is difficult. The steps I've had to take are as follows:
1. delete AVRemote from Polyglot dahsboard
2. uninstall AVRemote from store tab
3. install new version of AVRemote via polyglot store
4. SSH into RPi and delete polyinterface and pyyaml lines from requirements.txt
5. Reinstall polyinterface v2.0.28 each time per xKings instructions
6. run install.sh
7. Add AVRemote to Polyglot via web interface

This works reliably but seems like a lot of steps

Thanks!

Ben

Also, a couple additional features, if possible, would be great:

-report back to ISY which app the chromecast device is running (none, Spotify, Google Play Music, Youtube, Netflix, default media receiver, etc)
-report back to ISY artist, track name
-report back to ISY current volume level (%)
-allow discreet volume level control (i.e. set volume to x%), in addition to current volume stepping that's allowed.

Thanks again,

Ben

Here's the deal with status updates. Status is updated right after command executed or on short poll.

If you don't see status updated right after command, it's possible device is not updating yet. I've put 1 sec sleep between command and update. Perhaps it needs to be bumped to 2 or 3. I will make it configurable.

Short poll - not related to executed command - can be configured in polyglot dashboard. I think it defaults to 15 sec. You can make it smaller but keep in mind it's a load on your network. But I think 5 sec is perfectly fine. Edit. After re-reading your post, short poll is what you need to adjust for status updates not triggered in ISY.

As for your other request, the latter 2 are easy.

The former 2 are hard - you cannot send arbitrary strings to ISY. It has to be pre-configured and pre-loaded (and requires Admin Console restart).

So app can be possibly added, if you pre-configured them in dashboard, similar to play lists. Find the command with pychromecast where it reports it. I don't have regular chromecast. Mine doesn't seem to report app. But just paste it here and I'll make blind change.

Artist and track name is even harder. Unless you, again, create those values by hand. Polyglot framework doesn't really support it right now.

We'll try to figure out why you cannot just update. But:

You should be able to just go into ~/.polyglot/nodeservers/RESTRemote and run 'git pull origin/master'.

polyinterface can also be linked locally, instead of updating your global installation by hand.

Not sure about pyyaml problem. That one you have to sort out on your own.

if I do "git pull" and then start the node server, subsequent "git status" will show that server.json has changed after the "git pull", therefore new "git pull" will fail as there are local changes. Either don't touch server.json programmatically or add it to .gitignore

Can you try to do 'git diff'? git shouldn't pick it up as changed if the content is the same. And it should only change when version or drivers change. So unless you make some explicit change, git shouldn't pick it up.

I'll separate generation command away from install but trying to understand what it could be.

Also, I've used to have it in .gitignore but polyglot store needs it.

Hi,

About an hour after the plugin started, I started getting errors in my log file, attached. I also lost status of AVRemote and most of its nodes in the admin console (image).

FYI, I restarted the nodeserver and for some reason it's not initializing any devices other than "bedroom speakers" (online) and "ceiling speakers" (status), even though it finds all the devices:

I assume that's why there's no online reporting or status for the other devices.

I think polyglot keeps the state and will not update if it thinks state haven't changed. But I'll take a look at your earlier logs.

Does the right click and "Query" on the nodes return status?

firstone · July 23, 2018

It seems like there's a problem connecting to one of your devices and that might have locked up whole node server. At least I don't see any communications but attempts to connect. That's controlled by pychromecast but I'll see if I can turn off this behavior.

I will need to reproduce this behavior before I can fix it. Not sure how long it's going to take. Probably a few days.

DaveStLou · July 23, 2018

I tried to update to the current version from 0.3.3 and I ran into a "pullRepo:undefined" error. So I uninstalled, deleted the AVRemote folder on the Pi and attempted to reinstall. After adding the server, it starts up but after a minute or two disconnects. When I look at the configuration it is empty which is different than I recall happening before. I remember adding my second Onkyo but I thought there were default, empty values already in the configuration file.

The AVRemote log ends with the following:

What versions of everything are you running? Do you know how to link polyinterface 2.0.28? pychromcast, unfortunately, causes this logger issue when it finds chromecasts on the network.

No, I don't know how to do that. Can you point me to instructions?

Here's how to install Polyinterface 2.0.28 and this will fix the logging error (complements of @xKing) :

mkdir -p ~/src
cd ~/src
git clone https://github.com/UniversalDevicesInc/polyglot-v2-python-interface.git
cd polyglot-v2-python-interface/
cp polyinterface/* ~/.local/lib/python3.5/site-packages/polyinterface/

Restart polyglot and AVRemote should work again.

firstone · July 24, 2018

A better way is to do this, after you git clone per above:

cd ~/.polyglot/nodeservers/AVRemote
ln -s ~/src/polyglot-v2-python-interface/polyinterface polyinterface

This way any successive install will not overwrite polyinterface.

So far I'm not having much success reproducing it. I believe it's a bug in pychromecast. Which doesn't mean I will not be able to fix it but I need to reproduce it. I have a couple of google minis - I'll hook one up tomorrow and pull the plug, hopefully this will get it into the same state.
