Q: Where can additional documentation on Ydoc data loggers using MQTT be found?
A: In addition to the info in the data logger manual, consult these documents:
https://ydoc.biz/docs/datalogger-mqtt-iot/
https://ydoc.biz/docs/remote-data-logger-configuration-by-mqtt-ftp-and-http/
T: When using a hosted MQTT broker they might apply rules conflicting with logger constraints like very long user names or passwords with diacritical marks. Most brokers can change these rules for you on request. More information can be found here:
