you may save state with state node also
Thanks a lot! So I have the current state. If I’m right “vana_magata” is the variable for the volume. So the volume is stored in “vana_magata”.
To be honest, I’m still not clear 
Can you please post the window screenshot of the “Function” node and the “Call service node” whict sets back to the original?
service node and data part:
{ "volume_level": {{flow.vana_laud.attributes.volume_level}}}
and i’m not using function node at all.
sorry screenshots are from different flows, but you should use flow.yourname
Hi, how did you get that output?
This is my flow:
[{"id":"f0e4ec9b.c55fd","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"17f121a5.e5dcce","type":"inject","z":"f0e4ec9b.c55fd","name":"","props":[{"p":"payload"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"on","payloadType":"str","x":970,"y":160,"wires":[["fcb04c1c.2d1d5"]]},{"id":"e555f204.9b437","type":"debug","z":"f0e4ec9b.c55fd","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":1250,"y":160,"wires":[]},{"id":"fcb04c1c.2d1d5","type":"api-current-state","z":"f0e4ec9b.c55fd","name":"g mini","server":"46a5f96a.e810e8","version":1,"outputs":1,"halt_if":"","halt_if_type":"str","halt_if_compare":"is","override_topic":false,"entity_id":"media_player.family_room_speaker","state_type":"str","state_location":"payload","override_payload":"msg","entity_location":"data","override_data":"msg","blockInputOverrides":false,"x":1120,"y":160,"wires":[["e555f204.9b437"]]},{"id":"46a5f96a.e810e8","type":"server","name":"Home Assistant","addon":true}]
This is the output I get:
play something on mediaplayer and look then debug
You don’t need to play anything, just media_player.turn_on, delay 1 second, read state.
I can’t seem to figure out how to set the volume back to the original.
i tried using a call service node with {} or with
{ “volume_level”: {{flow.var_name.attributes.volume_level}}} but they don’t work
here’s my flow:

the initial volume is set to 0.1, msg1 returns 0.2 and msg2 returns 0.2 and I’m expecting msg2 to return 0.1
What do you think?

Not sure why you would need it to be a flow variable. But I think the issue is that you don’t have the" "
When you see your json like this when you open it, something is wrong.
After editing it to and clicking done:
and opening it again you see the formatting is “correct” again.
and the red border is gone from here:
Hi
trying to copy your flow, can you let me know what was in your set.msg_payload?
edit: just saw your flow … thanks
Thanks
Fred
Here you have a node that let you set the announcement volume and after the voice message is played the initial device volume level is restored.
If you want to give a try here you can find more details about the node:

If you send a TTS message to a google device while it is casting Spotify from a cell phone for example, the connected device will disconnect, the TTS message will play then the music will not continue playback.
Have you experienced this?
There a couple of threads around like this one TTS Announcements, Google cast, Music - Issues and workaround
