Volume_Mute - Trying to set state, and not toggle

Configuration
1

Hi there,

I have an automation that mutes the TV on the hour, then unmutes it again 5 minutes later.

This mostly works.

I have two automations, one for each. However I have found that if you run the same automation twice, it behaves as a toggle rather than a set state.

I have a condition in each that says if the TV is muted/unmuted do the other.

Any insights would be much appreciated:
