Philipp Zehnder commented on STREAMPIPES-461:
---------------------------------------------
Hi,
yes I know that the problem was with the MQTT adapter, I only wanted to check
if the problem is with the JSON format or if the problem is with the protocol
(MQTT).
But it seems it is neither of that. The problem is with the preprocessing rule
transforming the float to an integer value. There seems to be a problem within
the current release (0.68.0). I also checked it with the current development
version and it works there.
We implemented many new cool features, like multi-user support and improved the
service discovery with consul. This should especially improve the deployments
in kubernetes setups. The implementation of the features is completed and we
are currently working on the documentation and testing everything for the new
release.
Do you need to transform the data type for your use case or is it possible to
keep it as a float for now?
