Hi all, I'm looking for the best approach to put an entire tag provider (or a certain folders) to publish plain MQTT (non-SpB) on change. I currently have an on-change tag event working (script below) but I'd like to design something more scalable instead of putting scripts on each tag. I"m thinking a gateway event could do this? Basically I'd like all the functionality of the MQTT transmitter but not have it in SparkplugB format. Script ----- tagvalue = tag.value system.cirruslink.transmission.publish("Chariot SCADA", tagPath, str(tagvalue.value).encode(), 0, 0) ---

Hi all, Referencing [this post](https://forum.inductiveautomation.com/t/mqtt-engine-error-processing-edit-for-tag-path-cannot-accept-children-tags/69578) on IA forum, and [here](https://docs.chariot.io/display/CLD80/MQTT+Engine+Custom+Namespace) on Cirrus Link forum, looks like if I use a custom namespace, it may be a work-around for SpB ---

Probably worth mentioning the new[ish] UNS Transmitter in MQTT Transmission, as this wasn't available at the time of this original post. - [https://docs.chariot.io/display/CLD80/MT%3A+Configuration#MT:Configuration-unstransmitter](https://docs.chariot.io/display/CLD80/MT%3A+Configuration#MT:Configuration-unstransmitter) - [Which MQTT Transmission Transmitter should I use - MQTT Modules for Ignition 8.x - Confluence](https://docs.chariot.io/display/CLD80/Which+MQTT+Transmission+Transmitter+should+I+use) ---

Ended up not using MQTT, MES vendor bypassed Ignition to go direct to the equipment controller with their native edge connectors. Ugh.... ---

Hi @Kevin.Collins I got it working and thanks for the links. I do have another question, I noticed in the broker when i send a temperature for example, there are two topics, Temperature.props = {} and temperature = {value:mysuff}. Any idea what the temperature.props = {} is used for and if I need it or can remove it? Thanks again!
