Sometimes it happens that even though the message is reported by code.py as published, the MQTT broker does not receive it - at least according to the output from mosquitto_sub -d -t "devices/terasa/shield". For better robustness it might make sense to subscribe to the topic and verify the message was received. If not, throw an exception to retry.

I don't this will help. The nature of the issue is likewise somewhere in the WiFi or TCP/IP stack.
