I am experimenting with Tasmota 8.2 on a Earykong TYMC-1 Door Window Sensor
(https://templates.blakadder.com/TYMC-1.html)
After installing it successfully I monitored it in node red and noticed that on every event (door open or door close) the device emits 13 messages. See the example below

Many of these messages are not needed in normal operation. Basically only the stat/topic/POWER messages would suffice.
The extra messages make the device less reliable, as it needs to transmit in a limited time, before it goes to sleep again. Moreover, it is an extra battery drain (however limited it might be)
It would be great if there is a mode (battery mode) that switches off these excess messages automaticaly, or a console command to do so manually

Kind regards,

Bert Haverkamp

Did you tried to play with logs settingsto see if you can reduce the traffic?
You can use a lower level logging to the WebLog and SerialLog both default to 2, MqttLog default is already 0.
A word of warning: your device communicate trough serial to the Tuya MCU, setting serial log to zero is probably not a good idea.

That was a bit quick to close. Could you please reopen?
Yes, I have set all log levels to 0 even. This has no effect.
I also made sure I closed the web interface, as I read somewhere that having the webpage open can have an effect on the messages. But also this has no effect.
The minimum I have is 0. The different power messages might be a problem with the way the device reports the changes, so I am looking into that seperately.
But the INFO and RESULT messages are superfluous in my opinion.
On the chat, blakadder mentioned this indeed a known fact but at the moment not configurable without digging into the source

Hello Theo,

Thanks for picking this up. And even providing the fix at such short notice! Much appreciated.
