Let's Control It

Any news/help, to get the 2-channel power measurement-chip BL0939 of the Sonoff Dual-R3 V2.0 to work with Espeasy?

Hmm so far I only found a Chinese datasheet.
At first glance it seems like it may be a mixture of both P076_HLW8012 and P077_CSE7766

As in it does use serial (like P077), but there's also mention of CF like pins to switch between voltage/current measurements. (like P076)

I did see Google mentioning ESPHome seems to support it (not yet looked at it), but it is quite a lot of work to "convert" ESPHome code to ESPEasy code as they often leave out quite a lot and focus on using a lot of core components in the ESPHome code.
Don't get me wrong as that's a perfectly fine way of coding, but since I'm quite unfamiliar with the ESPHome code base, it may take quite a lot of work to "convert" it.

Hmm on another site I found an English "datasheet" which is more like a summary of features and this one mentions it has I2C interface.

So I guess when this will be supported, it must probably have its own plugin.

What I've read is, that the BL0930 the i2c and the BL0939 is the UART-variant.

But plugin 076 & 077 doesn't read anything.

I would really be surprised if those would work, as P076 is absolutely not UART and P077 is using very specific way to decode any data.
Also I don't know which pins are connected to the ESP.

I will try to determine the pin configuration (BL0939 <-> ESP32) on the existing hardware.

I'm also going to give Tasmota a chance...


Edit - Here is a summary of the complete pin assignment:

Can someone help me, to port this BL0939 tasmota plugin code to an espeasy-plugin.

I can done tests and if necessary, I could also send a DualR3 V2 by post for testing.

The Sonoff DualR3 V2 works under Tasmota, but I love the EspEasy interface and how easy it is to use the rules.

This subject is drowning somewhere in my "things I'd like to fix in ESPEasy" list (that's an actual list, but I just did not call it my TODO list...)

Maybe just create an issue for it, so it is more like an actual todo list
