Hi

I have a Logo 8.4 that controls a few lights using relais. I am using homeassistant with the modbus extention to turn the lights on and off. In homeassistnat i have configured a few swtiches; this works quiet well, as I see instantly the status of a swich/light.

Now i want to implement also pysical push-buttons to turn the lights on and off. The solution I would actually prefer would be that the buttons change the status of the switches in homeassistant and respectively the lights contected to them.

This doesnt seem possible. Can someone give me any idea how I could get this thing to work?

I tested the method with buttons in home assistant. that way I also needed to put some indicators next to the buttons to monitor the light status. 

but the indicators sometimes needed a couple of seconds to show the actual status of the lamp. how can i improve that?

LOGO Network output. Map real output status to Modbus coil address via VM area (in LSC ethernet mapping table) and read (poll) in HA Modbus coil status. Minimum interval seems somewhere near 100ms.

Setting LOGO as Modbus slave device is a bit harder in this case, but this prevents need for HA constant polling.
