What is the new downlink topic for 4.5?
I cannot see this topic published on my MQTT Server.
application/APPLICATION_ID/device/DEV_EUI/command/down .

OK Now. I can downlink from Home Assistance and MQTT Client.

Problem is solved. We can send Downlink via Android app now.

Would you mind sharing what HA Addon do you use and what MQTT topics are you using to push to Home Assistant?

No special addon is needed. I used Entities Card. Topic to push downlink is
exactly as it is described in manual. application/APPLICATION_ID/device/DEV_EUI/command/down

Payload must also includes devEUI.
