revert changes in files not related to the driver. Take a look in other drivers how Tasmota logging is done

Hi @Jason2866 I reverted changes in unrelated files, and fixed logging. Best

Do you expect only to read higher new values? Comparing new value to old value this way will never show lower values....

[woczach]

It was obvious for gas existence, and I am bit not sure, as I consider gas detector, as kind of canary and we sent data like every 5min i want highest value. I don't want last zero value to hide positive high value that was before.

[sfromis]

IMO, reporting false values to satisfy a specific intention should not be how a sensor driver works, but instead to be handled backend where you can react to the changing values, and decide what to do after getting an alarmingly high value.

Connecting to an ESP32, you could also use Berry to create logic about how to react to changing values, and even create an additional sensor keeping up the max even after the real reading fell again.

[arendst]

This is very expensive memory use.

Redesign your code to use floats and ints from DFRobot_MICS_data. Then use Tasmota specific "float to string" code like

ResponseAppend_P(PSTR(",\"DFRobot_MICS\":{"\"Methane\":\"%2_f\"...,&DFRobot_MICS_data.Methane,...

ofc will do
