Got this sensor up and running now. Comparing it to my old clamp meter the kWh reading was reading 2-3 times higher, the Watts was about right. I added a 0.1uF capacity across the ground and data pins of the sensor and it is working well now.
The graph below shows the comparison of my two sensors. the old clamp meter is Energy previous hour, the new pulse sensor is Temp energy previous hour
You can see they are not aligned, until about 20:00 when I added the capacitor and they drop in line.
@Michiel-van-der-Wulp There was a discussion early this year 2021 on this issue,
see: Contribution Issue with CLA and clahub.com
But unfortunately there is no feedback for a solution from the core team for now.
@Serj-Sam there is a pull request included in that pr. Once this is merged it will be available in development, later in the next release.
If you just downgraded the core, that is persistent until you upgrade the core to 3.x again.
@gryzli133 I have a number of MySensors devices using RS485, it would be interesting to try to run PJON protocol over RS485, it seems like there is such an opportunity, but I could not figure out how to use it in the MySensors library.
@lood29 That is correct, assuming the same radio technology is used. Typically, you set up a separate gateway because you want to run a sensor network on a different radio family due to longer distances or similar.
@BearWithBeard No need to say sorry! You did point me to the right direction, I was clueless
I've tried a different RS485 DE pin, but still no luck.
#define MY_RS485_DE_PIN 4
I've seen people mentioning RS485 transport here in the comments but I'm not sure if anyone actually did test this combination (RF24 & RS485).
