Capture Blinking Digits
The Feature
My meter blinks the digits every 10 seconds or so for 0.5 seconds. This makes it very hard to capture.
Could we detect first poll for something dislayed and then stard recognition?
This would need another module which continiously analysis the camera picture, maybe even in a kind of video mode. This is a major developent and not planned at the moment. Also it would require a deeper change in the internal logic, as this is based on a constant time triggered flow. Effort rather high - currently not planned.
I have this request as well, since I have the same measuring hardware.
One way would be to have a long shutter time and not use the flash. By this, the numbers should be caught in the image. The other option would be to be able to somehow trigger a switchbot to press the button (black button right of the display) that will keep the numbers visible for a longer period of time.
Would love this too because my counter displays values only periodically. Would it be possible to read them anyway with an uneven polling time so that you will take a picture of the numbers sooner or later. How long is the processing time for a taken picture?
I do not know how fast the picture taking is of the esp32, but in stead of video you could take a serie of pictures, and then use the picture which has no NaN? this is off course a big change in the way it work now.

Did you find any solution for this?
I am closing this request, because it is not feasable with the way the project works. We would have to implement video recording and realtime analyzation. The ESP for sure has not the power for it.
