===Message/Power: Multi===
The '''Message/Power: Multi''' Condition includes checks for the current <span style="text-decoration: underline;">States</span> of Power channels. If a Condition checks for a power channel state to be On or Off, then that Condition is true even if the power was set previously. It doesn't have to act like an event that just triggered. Note that at least one of a Multi's conditions needs to be triggered during the previous cycle for the script to activate.

<div class="spoiler">'''<span style="text-decoration: underline;"><span style="text-size: 15px">Detecting Power State Broadcasts</span></span>'''
Power broadcasts can be detected by either the Message: Received or Message/Power: Multi conditions. Power: Check simply detects broadcasts for On or Off States. It is only triggered when a Power State changes to the State it's set to listen for (On or Off). It will not detect when an action attempts to set a channel to its current state (no broadcast).

Message/Power: Multi can be quite complicated, but it detects Power change broadcasts just like the Power: Check condition does. It also has a Toggle option which detects a Power broadcast whether it's changed to On or Off. A Multi condition with Minimum of 1 with only one Power condition set to On or Off works exactly like the equivalent Power: Check condition. If the same script is changed to the Toggle setting, it detects both On and Off broadcasts.

'''<span style="text-size: 15px"><span style="text-decoration: underline;">Testing Power State On/Off Values With Multi</span></span>'''
Message/Power: Multi is the only way to test the value of a Power State outside the moments it gets changed and broadcasts. The Power State On and Off conditions within Multi conditions evaluate to true (and count as 1 for the Minimum to trigger setting) whenever that Power State currently has that value. It's not limited to when Power channels broadcast when they change. However, at least one of the conditions set in Multi must be broadcast to trigger the Multi condition.

The Power State Trigger and Message Send conditions within Multi can only trigger as a result of broadcasts.</div>
