@felmue Thanks so much, that fixed it...

@JourneymanWizard Please Email M5Stack support directly and PM them using twitter.

@erkel
It is working now.
Just a noob issue.
It was the endianesse of the values. it gives the output as expected when converted to little endian, rather naturally reading the value.,

@felmue Thank-you - I had completely misunderstood :-)

@ajb2k3 The relay was not connected. I connected the Core2 directly to a Hub and used the following code. Do you see something that could be the reason for the error?

@mippen
which actually module are you using?

@felmue

Okay, I will try to do that once I've got the required HW and SW to do so.
Thanks for the tip.

@ChSimon My pleasure!
M5Stack releases a new gadget or two every week!
They need to support us Arduino IDE guys and the UIFlow with new drivers (libraries) and examples.
The esp32S3 variant has been a nightmare for then, apparently.
The 'esp32 by Espressif' board def, shift to ver3 was seismic.
This Community website is a resource for them because we find the problems and complain. then their engineers hunt it down and correct it.
The new Unified library helps a lot.
We have a DIY hobby!
Cheers, Terry.

@lnsy-strs
yes you can

@Bipman I don't have one at present but I wonder how we'll it will work with the CoreMP135.

Hi Win,

My is not working too.

Pinout is the same as stated on https://docs.m5stack.com/en/unit/unit_cam

But in Homeassistant ESPHome generates these errors:

@ajb2k3 thanks.

I did not there was a different port version of the sensor?

@ioamas
According to the schematic diagram, the 5V of the Pogo pin is directly connected to the VIN pin. So I think maybe you can determine whether the Pogo pin is connected by judging whether the battery is connected

Hello @ioamas

thank you for reporting back. I am glad to hear you got it working.

And sorry you had to sort out a not so well assembled Battery Bottom2.

Thanks
Felix

@teastain thanks for your response, I understand that.
