Need help for understand dzVents

[albebert]

Hello there,

Since the Yamah plugin is not working anymore ( :'() i'm trying to do that i wan't with virtual switch and dzvents.

but i'm a sysadmin not a developer so difficult for me.

So can anyone help me to do 2 simple things please ?

that i wan't :

- a timer trigger that check the yamaha amp status and change the virtual switch (dimmer) according to amp status.
- change volume of amp when i change it on the dimmer virtual switch.
- change the dimmer volume according to amp volume
- add a selector to switch betweens input (and change it when input is changed directly on amp)



The amp work with http GET (and some POST) and return JSON.

for example in order to get status :

curl -s http://ampli-salon/YamahaExtendedContro ... /getStatus

return :
{"response_code":0,"power":"standby","sleep":0,"volume":76,"mute":false,"max_volume":161,"input":"hdmi5","distribution_enable":true,"sound_program":"surr_decoder","surr_decoder_type":"dts_neo6_cinema","direct":false,"enhancer":true,"tone_control":{"mode":"manual","bass":3,"treble":0},"link_control":"standard","link_audio_delay":"audio_sync","link_audio_quality":"uncompressed","disable_flags":0,"actual_volume":{"mode":"db","value":-42.5,"unit":"dB"},"contents_display":false}

so the interesting value are :
.power (standby or on)
.volume
.input

so i started by creating a event in domoticz UI using http request

Code: Select all

return {
	on = {
		timer = {
			'every 1 minutes' -- just an example to trigger the request
		},
		httpResponses = {
			'trigger' -- must match with the callback passed to the openURL command
		}
	},
	execute = function(domoticz, item)

		if (item.isTimer) then
			domoticz.openURL({
				url = 'http://ampli-salon/YamahaExtendedControl/v1/main/getStatus',
				method = 'GET',
				callback = 'trigger', -- see httpResponses above.
			})
		end

		if (item.isHTTPResponse) then

			if (item.ok) then
				if (item.isJSON) then

					local status = item.json.power  -- just an example

					-- update some device in Domoticz
					domoticz.devices('Ampli - Zone 1').updateText(someValue)
				end
			else
				domoticz.log('There was a problem handling the request', domoticz.LOG_ERROR)
				domoticz.log(item, domoticz.LOG_ERROR)
			end

		end

	end
}

so if anyone can help me to do this..

Thanks i advance

Hope this initial script will help to get you going.

Code: Select all

local scriptVar = 'Yamaha'

return {
    on = {
        timer =
        {
            'every minute' -- just an example to trigger the request
        },
        httpResponses =
        {
            scriptVar
        }
    },

    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = scriptVar,
    },

    execute = function(dz, item)

        local testing = true
		local maxVolume = 161

        local volume = dz.devices('Yamaha volume') -- switch (dimmer) 
        local input = dz.devices('Yamaha input') -- selector switch with all possible input strings as levels

        if item.isTimer then
            dz.openURL({
                url = 'http://ampli-salon/YamahaExtendedControl/v1/main/getStatus',
                callback = scriptVar,
            })
            return
        end

        if testing then
            item.json = dz.utils.fromJSON('{"response_code":0,"power":"standby","sleep":0,"volume":76,"mute":false,"max_volume":161,"input":"hdmi5","distribution_enable":true,"sound_program":"surr_decoder","surr_decoder_type":"dts_neo6_cinema","direct":false,"enhancer":true,"tone_control":{"mode":"manual","bass":3,"treble":0},"link_control":"standard","link_audio_delay":"audio_sync","link_audio_quality":"uncompressed","disable_flags":0,"actual_volume":{"mode":"db","value":-42.5,"unit":"dB"},"contents_display":false}')
            dz.utils.dumpTable(item.json) -- just for test / debug
        end

        if item.isHTTPResponse and item.json then
            volume.dimTo(math.floor(item.json.volume / maxVolume)).silent()
            input.switchSelector(item.json.input).silent()

        else
            dz.log('There was a problem handling the request ', domoticz.LOG_ERROR)
            dz.log(item, dz.LOG_DEBUG)
        end

    end
}

Ok it's work !

just a litle problem with volume max volume on amp is 161 so when volume is at max on amp, dimmer is at 61%.

i've added htttp query on selector

so for now, selector is working great, power too.

so need to ajust dimmer volume to amp volume, and control amp volume from dimmer volume.

i'm not alone that have a problem.

and now, my old domoticz is not working anymore with this plugin :

i d'ont know why, issu open on git but no response from dev :'(

so i manage to bypass this

Adjusted the above script to convert ampVolume ( 0 - 161 ) to dimLevel ( 0 - 100 )

thanks ! (i've do this to achieve same thing : volume.dimTo(item.json.volume/161*100).silent() )

so now a little problem, when i change dimmer level, amp goes ON, but the script seems to change level each time, so if amp is off, when the script run, it goes ON.

there is a way to change this ? (if dimmer volume change don't power on) or i think that we can add an condition like this :

Code: Select all

if item.isHTTPResponse and item.json and item.json.power = on then

and the last thing, need to change amp volume when i change dimmer volume.

No but maybe you can split the functionality. So one dimmer to display the volume and one switch to switch power of the amp?

and the last thing, need to change amp volume when i change dimmer volume.

What is the url to set the amp volume?

[albebert]

there is the url http://ampli-salon/YamahaExtendedContro ... ?volume=50

i'm testing a thing but no luck

Code: Select all

  if item.isHTTPResponse and item.json then
            dz.utils.dumpTable(item.json)
            if item.json.power == on then
            volume.dimTo(math.floor(item.json.volume / maxVolume)).silent()
            input.switchSelector(item.json.input).silent()
            volume.quietOn()
            end

        else
            volume.quietOff()
        end

the "if item.json.power == on then" does not math (i've the dump table in log so i enter in first if but not in the second.

edit : ok with right syntax it's work "item.json.power == "on' "

if amp is off, script d'ont update dimmer volume (not needed) !

[waaren]

there is the url http://ampli-salon/YamahaExtendedContro ... ?volume=50

For setting the volume based on dimmer
Something like ?

Code: Select all

local scriptVar = 'Yamaha'

return {
    on = {
        timer =
        {
            'every minute' -- just an example to trigger the request
        },
        devices =
        {
            ''Yamaha volume',
        },
        httpResponses =
        {
            scriptVar,
        },
    },

    logging =
    {
        level = domoticz.LOG_DEBUG,
        marker = scriptVar,
    },

    execute = function(dz, item)

        local maxVolume = 161

        local volume = dz.devices('Yamaha volume') -- switch (dimmer)
        local input = dz.devices('Yamaha input') -- selector switch with all possible input strings as levels

        if item.isTimer then
            dz.openURL({
                url = 'http://ampli-salon/YamahaExtendedControl/v1/main/getStatus',
                callback = scriptVar,
            })
        elseif item.isDevice then
            dz.openURL('http://ampli-salon/YamahaExtendedControl/v1/main/setVolume?volume=' .. (math.floor( item.level * maxVolume / 100) ))
        elseif item.isHTTPResponse and item.json then
            volume.dimTo(math.floor(item.json.volume / maxVolume)).silent()
            input.switchSelector(item.json.input).silent()
        else
            dz.log('There was a problem handling the request ', domoticz.LOG_ERROR)
            dz.log(item, dz.LOG_DEBUG)
        end

    end
}

[albebert]

hum i think that another script that react to dimmer change is better no ?

[waaren]

hum i think that another script that react to dimmer change is better no ?

Why ?

[albebert]

because it can react on change not after 1 minute.

i think

[waaren]

because it can react on change not after 1 minute. i think

That's why I added the devices = in the on Section. The script now also reacts immediately on a device change

[albebert]

sorry missed that !

so i tested, and amp goes of after 1 minute :/

amp is on, don't touch anything, but dimmer is set to 0 so power off
