Thanks for links. I have been using the information and resources and have several Pi forwarding MQTT from GPIO serial connected devices over long range radio.
Two tings here really…
The first key bit of information and example I am missing is understanding how to translate this to using the handy phone utility MQTT Dash. I have limited experience of using MQTT so just need some graphical examples or specific text example of what goes into which box. E.g. what gets put into the configuration screen here:
I have the pre screen sorted that sets up the
Name (can this be anything ?)
Username from settup
user password from settup
Client ID (must this be unique per phone ? )
I think I have a pretty sound understanding of the structure of MQTT and pub / sub etc. It is just how to make the folders and exact formats within the detail of filling out the boxes I am missing.
The documentation and data types is good and extensive but the way the information is put into python In the phone here for MQTT ( and python examples ) I am still working on making the connection. I reaslise seems to be exact
The documentation section is good and covers the 4 main methods and code examples Extensively. The Manually Publish section is good. I guesse I am asking for at least a starter along the same lines on Dash MQTT.
The Documentation section I feel would benefit greately from having a section with just a few very basic few lines of python for a minimum of Pub-Sub Digital-Alalogue. Just txt.py would be fine. No need for extensive video and screen captures unless time and space permit. At present we seem to be diving in and out to one off various third party project examples that then need reverse engineering ?
I have python working and several projects with multiple variables passing easily but all variables in coming at present are degree c data type I.e. some simple py lines of client.celsiusWrite(8, data) alternative data types. I have atempted without success to change celcsius in the python so far but not ‘cracked it’ yet. ( Or the tpye can not be changed once already added and config’d on the dashboard).
The way Cayenne accepts my present pythin examples and faithfully and Very reliably sets up new devices is sheer magic ! Well done on that front.
The Documentation is extensive and ‘good’ but a little bit hidden wayyy down the bottom ?. New sub section pehaps / edit ?
And perhaps just a few lines of pi py please ?
