New to M5Stack... A few questions about UIFlow

meatpuppet

Hi,

I am new to this community. I started to develop an UI using UIFlow to show MQTT data from my home automation server.

However despite all my digging I could not answer the following:

When I add Python code to UIFlow, I get an error message stating that the Blockly tab does not correspond to the Python code. Which is normal since I "hard code" additional stuff. Any fix for that?
MQTT seems to cause some issues: when I use PahoMQTT to publish multiple messages, the M5Stack does not receive them. I have to make an individual connection for each publish that I want to show on the M5Stack. Same issue for retained messages: once a retained message is published, the M5Stack simply won't connect to the broker anymore. May I know what protocol for MQTT is behind UIFlow? This may be the issue.
I do not find a way to turn the screen off and get some power saving mode in UIFlow. Are light sleep and deep sleep available, and if so is there a simple sample code to show how a button press can switch sleep mode until another button press wakes the device up?

Thanks a lot for your support to all these,

Regards,

A1 you can try using the Execute code block but it only supports one line of code per block.

Thanks for this quick first answer.

Is it necessary to switch to another environment to get all these features? Such as ESP32 library on Arduino...

@meatpuppet the problem is that while I am working on documents, I haven’t had time too look into the MQTT issues to see what’s happening (I’m not a coder so I can’t fix things) but when I have time I look into issues and give feedback to support. I see a lot of the same MQTT issues popping up and wish I could help. The 1.4.4 update caused a lot of issues, and so finding time to use and break things is something that needs a lot to f help and support from users. I am wondering if the current issues are due to connections between the device and the server.
