hi

I'm would like to use a  WiFi energy meter WEM3080T .

my installation is 3 phases and i have au PV systeme on a single phase (small power of 500W max at the moment)

actually, it's connected and runs well, but sometimes there is too much sun and the PV power is higher than my home consomption (ex: 150wh in home and 350 wh from PV system) so  the difference goes to the grid (200wh). i must have a special contract for that and i dont want it. my

i want to use the "overpower" to heat water by using a home made PV router.

in the document 7.7 " Integrate with Third-Party Server", i can see :

-"Working as a TCP client, the meter can post the data to remote TCP server every minute"

and

-"Working as a TLS client, the meter can post the data to remote TLS server every minute"

each mode it's every minute, not less.

i need  faster PV router made whit Arduino or Raspberry, less 1sec.

Hi,
There is two ways to get more data less than 1 min.

1 use our local api ,  please refer to  https://www.iammeter.com/docs/integrate-with-PVOutput

The data would be refresh every 6 seconds, so you can also call this api every 6 seconds.

2 use http post method (not tcp or tls) in integrating with third-party system. Please refer to https://www.iammeter.com/docs/docker

You do not have to use our docker system. It just an example.
There are three method in sending data to other server, tcp, tls and http post.
Tcp and tls will be update data every 1 min, while http post will update data every 6 seconds.



Sorry ,I forgot the function of post data to other server every 6 seconds is only present in the firmware version above 1.75.48.
So please upgrade to the latest firmware version firstly.

Hi,

6 Seconds is good but I have too a application that need the current value faster. A Update in the local API every Second, better all 500ms.


Is this possible to make this in next Firmware Release. Is there a way to integrate this in the webpage to change the value self. Thanks for anwser.

Hi,

In my opinion ,if you need sample rate more quickly(around 1 second), the RS485 interface with modbus protocol is a better choice.
