Battery, but the battery looks fine.
If I turn the power on and off. the device picks up. Also, we are talking about minutes not days. After a full charge.

@felmue Thanks let's see if I can figurate something.
The only thing that I want is to know that the battery is low. I don't really need an exact number.

Hi everyone, I am having an issue.

I create a program with uiFlow where I subscribe the decide on a topic in mqtt and change the screen with the text in the topic.
The program worked perfectly for a while, but it looks like it lost the subscription to the MQTT broker because after a period of inactivity stop to reacting to the topic change.

The broker seems to work fine with other devices, so I assume that the problem is on the M5.

Do I have to loop m5mqtt.start() ???

Also, the keep-alive is on 300

@felmue thanks for answering, how I can use this information to know how much battery left is in the device? Sorry if this is a very basic question, I am learning.

I can't find a way to get the state of the battery using UIFlow. Any hint?
