Hello, I am trying to create a button to do two actions at the same time with one button (i.e. turn on my left and right speakers), so I created, which is not working:
type: button
tap_action:
action: toggle
entities:
Thank you!
You have to use ‘call service’\toggle and then choose you entities. For the start
type: button
tap_action:
action: call-service
service: switch.toggle
service_data: {}
target:
entity_id:
- switch.office_guest_bed_rm_speakers_switch_4
- switch.office_guest_bed_rm_speakers_switch_3
entity: ''
show_state: true
icon: mdi:volume-high
name: Office Speakers
Some reading for you as you will want more stuff sooner or later

And have a look at this advice:
Thank you, soooooo much! I have been trying to create this for 3 days with no luck, and that works!
In addition, how would I create the color to change when turning the button on or off? Right now I have, and it doesn’t work:
type: button
tap_action:
action: call-service
service: switch.toggle
service_data: {}
target:
entity_id:
- switch.office_guest_bed_rm_speakers_switch_4
- switch.office_guest_bed_rm_speakers_switch_3
entity: ‘’
show_state: true
state:
Thank you so much again for your help. I am not a programmer, nor do I have any formal training in this area, but I am slowly learning how to do this in HA.
Happy I could help as I got no programming background myself. 
Changing the icon color to your needs won’t work in a regular button card that is why I added the reading list above, esp. the custom:button-card.
You would have to use a template for the icon_color which the regular button-card is not capable of.
And three more things:
Thank you!
