Yeah ok, so this is not ideal for computing one devices energy usage(without braking its cable), shame :/

But, i would still prefer clamp. Using clamp i wouldnt need to take wire off from main electric box to fit it in to wire.

Hi ! The PZEM-004T is in the "testing" mode, and I'm pretty sure we didn't port it to the 2018-03-13 version. I might try to compile it for this version on week-end, but won't have any hardware to test it anymore :/ Or you can use our development version here https://www.letscontrolit.com/forum/vie ... =30#p21383
Hi, aleph0
Did you have time to compile a newer version? ))

Officially supported in Tasmota 5.10.0b :D
On which device name ? Just did install latest sonoff-tasmota, but cannot find pzem under devices ?

I can see it enabled in config.user, but its not in devices list ? Is it supported only through sonoff device ?

No problems ! I can test the new version.
And report the results. )))
I would be happy if you trust me to test the new 2018-03-13 version. )
Ok then ! Here it is in version 2018-03-26, tell us what ;-)

I expect some problems because I recompiled it against the ESPeasySoftwareSerial provided in the 2018-03-26 to avoid duplicating the libraries, but it's not the version recommended by the original author of the plugin. So let's try and see !

JST 2.5 XH 4-Pin Connector Plug

That seems to be the connector that fits to white 4pin connector on pzem.

Hello,

Today I tried to setup PZEM-004t with domoticz but without success.
I received this error in domoticz log:
2018-04-01 20:00:49.208 Error: EventSystem: in pzem1: [string "--[[Script to read infos from espeasy/pzem-00..."]:42: bad argument #1 to 'match' (string expected, got nil)
Image

Can you please tell me how can solve the issue?

Regards

PS. I solved the issue with domoticz update.
