After you complete the steps in the previous post, you will need to edit a proper .yaml file that has the settings and configuration for your meter to communicate with Home Assistant. Also, this will tell ESPHome how to compile the firmware it will upload. See button "Edit" in ESPHome component in ...

Hi All, I would like to report the successfull outcome of my experimentation with the meter.

Hello everyone! It's been awhile since I've last replied to this thread (or took part in any development whatsoever), however yesterday I managed to sorta finalize my `hekrapi-python` library adaptation for ESPHome, and put my power meter on it. So far it has been a blessing to switch from Wisen ...

Hi to everybody. Has anyone got a workaround to be able to monitor and record historical data? I have once been able to see past information on Wisen App, but never got the chance to see it again. The provided Wisen App is not useful at all in this regard. Many thanks! Hello, I am also trying to ...

Hi, finally got home after some days abroad, and have found that the meter has the WiFi disabled. Pressing the settings button (arrow) as indicated in the user manual will not enable it. So I am now stuck. Has anyone here have an idea if it is possible to enable wifi using the RS485 protocol? Is ...

The contact information I used related to the meter itself are: [email protected] [email protected] They kindly replied to my questions. Can you please comment if you were able to set up the Wisen App? If so, you should be able to grab meter information to use with the Hekr Addon with Home ...

I wrote to the author of Hekrapi. He made an example of how to use api. wait... I was in contact with him, and he kindly helped me set up Home Automation (HASS.IO). There are some caveats, but finally I am able to see my meter outside of the crappy Wisen App. Issueing the following command: echo ...

I will keep monitoring the thread.

I will appreciate instructions or directions on how to make this work.

Hello, for all those who have this meter. I share some libraries that I develop through reverse engineering to this module. With these libraries you can fully control the module. To program the module unfortunately it is necessary to disassemble it and flash the esp8266 inside. For now, i share ...

As I understand they use:

• custom ESP8266 module

• ESP8266 communicates via COM

I will try to sniff COM data

WiFi can be replaced with ESP8266-01 for custom firmware tests

Hi, any updates on updating the firmware/making it work with Domoticz?


Thank you!

Just received my meter with WiFi Not tested/opened yet. I will try to use COM sniffer - https://www.compuphase.com/electronics/rs232split.htm Then custom firmware could be build to integrate this meter with other smart home software I use HASS, not Domoticz. Also I will try to use WireShark to ...

Hello! I'm kinda new here, and I'm coming from a different background (Hass.io), and I bought a single phase one for myself just to play around and do some automatic submissions on the side. I have a ESP8266 version, and I think I managed to break the protocol of this small thingy. I'll set up a ...
