Thanks JT, that’s interesting, especially if you are already using MQTT. I think it boils down to what integrations/apps that you are already using that can do the job rather than adding any more moving parts. I am looking at using Telegram notifications to send commands to Tasker now since that is what I’m already using for alerts. And it’s free.
In the HA Tasker thread, @CentralCommand documented how to use rest_command to send HA messages to the Tasker AutoRemote plugin. I found there is also a SimplePush integration in HA which is another inexpensive paid app for Android to receive messages. Ditto for PushBullet, and HA’s Android Companion.
