The MQTT Push Client app is a universal solution for push notifications on mobile devices. The app and server solution works with all MQTT environments. Any MQTT client can issue push notifications which will appear on the mobile device within seconds.

The RadioShuttle LoRa boards can also send notifications via the LoRa to MQTT gateway software which is included with the boards. The push server is hosted by RadioShuttle.de.

It is free of charge for noncommercial use.
