Rain data does not reset at midnight

We had 2.4 mm rain yesterday. Today it still shows 2.4 mm with no reset at midnight. Other data is normal.
I didn’t have this problem so far. What did change yesterday evening was enable to plot the AQI. I’m getting the pm2.5 from my sensor through an airquality2.txt file. I’ve been logging it for a while but started plotting it on the main screen only yesterday. Besides that, the pm2.5 and aqi were calculated to negative values since my sensor is not calibrated and could send such values occassionally.

I didn’t reset the WD yet.

was there any error under view, program event log?

Unfortunately, I’ve restarted the WD before checking it. Now the log is clear. I will see if it resets at next midnight. In the meantime, I’ve fixed my sensor not to send negative numbers (set to 0 instead). Since I did nothing else, I suspect it has something to do with plotting the (negative) AQI. Let’s see.
Could you tell where should I set the rain to 0 for today? It is a bit unclear. Thanks!

Today it did reset so all back to normal. Rainy days are coming now, I’ll keep an eye.
