Hi everyone, I just flashed my first smart socket using a T34 and BL0937 with OpenBeken. 🎉 Had to fiddle a bit with the baud rate, but once that was sorted, everything went smoothly. After calibration, the socket is working well. However, I have a question regarding the BL0937 message output:...

This is related to stat_updatesSent variable in code Long story short, the values are published via MQTT only if there is a change between reads or if given time interval between publishes passes. I don't remember the exact logic behind it, but it just reduces MQTT overheat, more or less.

Hi everyone,

I just flashed my first smart socket using a T34 and BL0937 with OpenBeken. 🎉 Had to fiddle a bit with the baud rate, but once that was sorted, everything went smoothly.

After calibration, the socket is working well. However, I have a question regarding the BL0937 message output:

What do the terms "changes sent, skipped, and saved" actually mean? Are these related to MQTT messages? In my case, the skipped counter keeps increasing steadily, but I have no idea what it signifies. I couldn’t find any explanation in the GitHub documentation, wiki, or forum posts.

Also, a newbie question: How can I reduce the output shown on the "main" page? Is that controlled via the log level settings?

Thanks in advance!

Best regards, Dirk
AI: Could you let us know which version of the OpenBeken firmware you’re currently running on your smart socket?
OpenBK7231N_QIO_1.18.145
AI: Are you using MQTT integration with your setup, and if so, could you share a bit about how it’s configured (e.g., enabled/disabled, broker settings, topics used)?
I don't use MQTT atm.

This is related to stat_updatesSent variable in code https://github.com/search?q=repo%3Aopenshwpro...BK7231T_App%20changes%20skipped&type=code

Long story short, the values are published via MQTT only if there is a change between reads or if given time interval between publishes passes.

I don't remember the exact logic behind it, but it just reduces MQTT overheat, more or less.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
