PZEM004T and display - Githubissues

fragolinux commented 5 years ago

hi, is there PZEM004T support in the DISPLAY precompiled firmware? I'd like to add a 1602 i2c display to show actual values of the PZEM004T sensor...

or, how to know what features are enabled in standard precompiled firmwares? Thanks

What about reading release notes?

What about reading release notes?

did you? Already checked, of course, and there's no reference on what's included in DISPLAY edition, in RN...

anyway, i flashed the display edition and setting the device as generic i can see that i can select pzem rx and tx, so i'll try this afternoon and eventually close this issue

nope, no pzem info in main page, even if setup as such:

while just switching from the DISPLAY edition to the standard (IT version) one, the pzem appeared on main page... so it seems i just need to compile my own firmware with both display and pzem support :)

arendst commented 5 years ago

@fragolinux Correct!

To make the display binary as small as possible (prefferably < 500k) I remove the ENERGY_SENSOR functionality. You can find this in file sonoff_post.h lines 225 - 248

why the display firmware allows selecting a not included device, anyway? Firmwares list any supported device in their combo boxes, even though not compiled in the installed version? Thanks, i'll post my setup once completed :)

That's a matter of admin. I will add the (un)defines to solve this.
