After upgrading the firmare to 2.75.92 the RUN led is blinking a lot.
Here is a small video https://www.screencast.com/t/ebw9WPnA3RA
Is this normal?
I see no problem in reporting data to cloud, but blinking that much seems odd to me.
Yes, it is normal.
After this upgrading, the wifi module would request the energy data every 0.5 second.(it is 6 seconds before)
So the RUN led is blinking faster.
Please note, that the upload interval to the IAMMETER cloud is still 1 min. If you upload data to your own server, the minimum upload interval is 12 seconds.
If you want to get the data refresh at the fastest frequency(0.5s/s), the only method is to use the Modbus/TCP
