Hi,
I would like to know if there is some plan to implement and support the zero export with AhoyDTU using DDSU666 smart meter. I am very please to use AhoyDTU ‘Good job Guys’.
thanks
Maybe in future versions with the Fusion PCB. Fusion V2.x has an RS485 connection. But if you run a RasPi, why do you not implement it with it by yourself ?
Thanks for your answer. To answer your question, coding is not something I like to do, anyway why not :-)
This project is driven from people who implement / test new features. As the maintainer I only implement features which I need or like, but merge almost everything people provided via pull request. Tell me a reason why I should implement this special power meter? Your last response sounded a bit snooty too me - I don't like that. Does this power meter use some common Modbus addresses / registers? Do you have a datasheet?
@lumapu, whoa my answer was absolutly not snooty, it was more I don't know how to implement. Sorry if my answer was not appropriate.
I am looking for such implementation because I do have such meter already in place, today I have Hoymiles DTU which use this for Zero injection. but I am not happy with this private and closed solution. as far as I know yes this meter use common addresses/register. Mine is DDSU666 Single-phase I have a paper datsheet, below is a link of this meter. the communication with this meter is done using rs485.
In case this project will be supported, I will be very pleased to help and test it under my environment.

Ok sorry for getting you wrong.
If your meter does use common adresses I assume it can be supported once we implemented the RS485 feature for the Fusion board which @knickohr mentioned. Currently I'm implementing its ethernet shield which also has connectors for RS485 😀
That’s a very good news, many thanks for your answer and support, very much appreciated 🤩 Hopefully I do have 2 DDSU666, one from Hoymiles and second one which is more standard. If any help is required for testing let me know I will be happy to help. Take care guys, you are doing a very good job.
Hi, Could it be possible to get an update of this feature ? If you need beta tester, I will be very happy to help at least with DDSU666 smart meters.
If it can help, I build a .sh script to be integrated in the reserve85 project. The script read powermeter values from a DDSU666 Monophase using USB 485 connected to a raspberry pi 4 to perform HoymilesZeroExport.
