Does anyone know if the newly added GP8403 support in ESPHome will work with the GP8413 device? I can purchase packaged GP8413 module from M5Stack, but not GP8403.
I see that DFRobot has a library:
GitHub - DFRobot/DFRobot_GP8XXX
I’m not sure if that was used in the ESPHome support for GP8403 or not?
Per DFRobot, the GP8403 and GP8413 differ only in 12-bit vs 15-bit resolution.
Bottom line, if I buy device with GP8413, how likely is it to work with ESPHome GP8403 component?
I did find this PR:
@lupinglade - Thanks for spotting & noting that.
Looks like PR is still open, eh?
FYI- I did go ahead & try the GP8413 device (from M5Stack) w existing GP8403 ESPHome component, & it sorta works, but is very non-linear.
Can you post your solution here? I can’t get it to work. I can get the code compiling and installed, but the voltage channels do not respond. I suspect it’s something with a GIO mismatch.
