Send or receive entity id's from or to KNX to another entity

Hello there,

I try to send the value from one entity id to another one. Like an KNX entity id (Switch Pool light on/off) to an Jandy (Pool Control) entity on HA.

KNX entitiy id is: switch.light_pool_knx

Jandy (HA) entity id is: light.pool_light

I’ve found some solutions but no one works very well.
I would like to get the easiest way to pass through the telegrams in both direction.

Thanks a lot, Marcel

Hi :wave:!
The recommended way would be to only use one entity. You can control it from Knx using an interface device trigger. And you can send back the status, if needed, with expose.

Otherwise use an automation coupling those two entities on state change, but imho that’s more error prone.

Hi,

thanks a lot. I’ve use the automation coupling an its running great with binary DPT’s.
But what can i do to send a temperature value from KNX over the HA to the pool control? In KNX it’s an 2-byte DPT. I’ve find no solution for that in the automation menu.

Greets, Marcel

Either use a Knx sensor or, again, an interface device trigger with the GA (if you have your project loaded - otherwise a knx_event).
