Python Question

[toadleyb]

I have been reading and playing for days with the Echo Ha bridge and eventghost. I have all kinds of home automation running great but I am stumped on the following.

I have created a device in ha bridge called receiver. I use it to control the power off and on on my Denon receiver. I am trying to use the dim function to set specific volumes. I need to send the command MV30 where the 30 is the volume I want to set. I have the bridge sending the command as HTTP.denon.dim [u'30']. The problem I am having is sending this on to my Denon using python. The Denon expects to receive this with the 30 as an integer and the only way I see to send it is as a string. Here is the code I have.

Code: Select all

v = str(80-int(eg.event.payload[0]))
volume = "MV"+v
print volume
eg.plugins.NetworkSender.Send_Custom_Action(u'volume')

The log shows the command correctly as MV30 but it is not doing anything on the receiver. Any help would be greatly appreciated.

Could you instead change and try

eg.plugins.NetworkSender.Send_Custom_Action(volume)

[toadleyb]

tried that still does not work.

Well I don't completely understand it but I did get it to work. I am completely new to python so I have just been reading and trying things. Here is the code that finally worked. I am sure there is a better way but this works.

Code: Select all

v = str(80-int(eg.event.payload[0]))
volume = unicode("MV"+v)
print type (volume)
print volume
eg.plugins.NetworkSender.Send_Custom_Action(volume)

You were correct I did need to remove the u' in the expression. Thanks for the help.

why are you not just using the denon plugin??

and controlling it directly from EG without the middleman

I am using that plugin. This is a custom action using that plugin to send a specific volume to my receiver instead of just and up or down volume command. The line "eg.plugins.NetworkSender.Send_Custom_Action" uses that plugin to send the command to my reciever. It works great except that the plugin keeps losing its connection to the receiver.

how do you know it's losing connection??

i know with some of these network attached receivers if they are doing something else your request gets blocked. so what you may have to do is have the script send the folume command and then query the avr for the current volume and see if they match and if no or you do not get a response then to send the command again.

or does it tell you it's not connected?

and does the plugin for the avr have an option to do an automatic connection and one to do a static and have you tried both?

Thank you for all the help kgschlosser. It appears the problem is with my receiver dropping its network connection. Not an issue with Eventghost. I am working on troubleshooting that now.
