@Jon_Hope please share your code. I’d be interested to see if I can get this integrated.


(Jon) #23

Sure, I will send you a private message when I’m in front of my computer and can easily cut and paste.


(Paul) #24

Just wondering if you got any further with this? Or for that matter if anyone else has?

I’ve got an EU v2 and its reporting Volts at 89:

Are you all still using the DTH linked by @daleajones above.

Cheers

Ive got the mihome (Energinie) hub and whole house monitor. There is a smart app to hook that into smartthings.

Hub will also give you other connected device and swicth capability…

and here is the monitor

for smart app…


(Chris Irwin) #26

Hi Jon

I have a Wattson and Energyhive hub so would be grateful if you could share tyhe code you developed. I want to link my Wattson to Smartthings.


(Chris Irwin) #27

Hi Jon, please can you share your Wattson code. I have one and want to link it to Smartthings.


(Jon) #28

Hi, sorry I have not logged in for a while.

here is my code, though sadly im only here because my integration stopped working.

I’m currently pretty close to getting this to work with energyhive:


(Jon) #31

So just to update you I managed to get version 3 of the efergy device handler working with energyhive. I had to comment out lines 1052 and 528 from the code as written, because I think energyhive’s api is subtly different has has no support for the tarrif rate. Once those lines are gone it seems fine.

Good luck!

Hey, do you know where I can buy the Aeon HEM you’ve mentioned? I’ve just set myself up on InfluxDB/Grafana using your guide and would love to pipe in the power consumption data for my whole home
