I have an entity (heat pump status) that switches "on"off"hwc"  
I need to make it turn on for me only when it switches from "off to hwc" or from "off to on", not from "hwc to on" or "on to hwc".  
Now I have it like this, but it switches for me depending on which variant is switched on and not what it is switched from.  
Below in the attachment is what I want to achieve. This is how I do it in HA.

Welcome to the forums @Honzik1234

You're better off seeking guidance from the HA community - all your Nodes are for HA - and many here don't use it.

If, however, you want to skip using HA altogether - then please let us know what APIs your device is using (such as http APIs), as well a link to the device, and how it can be controlled.

Then, we may be able to guide you.

Alternatively show us what the incoming message looks like and tell is what outgoing message you want for the various switch sequences.

Rather than sending the event state node to current state nodes use a switch.

```

or use a trigger state node's custom outputs

The lower 3 outputs correspond to the rules in the custom output section.
