Thanks a lot. Just to log my experience here. I use a Deye and tried changing mine to 1 but the inverter tripped off and when it was power cycled, it defaulted back to 0 so I just updated on node-red instead and all is now fine. Thanks

Thanks can you kindly confirm where to find the unit ID? what I used on node red in the past was 1

Here is the settings that has been working fine for me. However, after a firmware update today, I have not been able to fetch data with the connection above. Does anyone know if something has changed with the Deye modbus register?

Hi, could you share the syntax you have in the switch node and function node (msg.topic...)?

Are you getting you data to mqtt using node-red? Could share the node-red flow?

I will also appreciate if @Bloubul7 could share the node red flow

Yes its working now, integrating with mqtt is my next challenge, i have mqtt already running could you share syntax of the mqtt import function?

Thanks for the help @Vassenreally appreciate. I was checking the modbus document but could not find the address for total PV, instead it has individual PV do you know?

Yes thats where the rj45 is plugged into

I have set it as serial yet i get same error, how about the serial type and other fields? Edit: Rebooted my pi now i am getting response

Can't find this on the list of nodes, searched for gate, perhaps need to install?

Have a look at my settings on flex getter, is that not correct?

Thanks a lot for helping out, now i have response(attached), but the next time i issued the query i started getting modus failure error again. So what could be the reason for this?

okay now i am getting a different error message(see attached), looks like the connection to the inverter is not established afterall. Guess i need to look at the cable again. I am clear on the converter side of the cabling, can you confirm if the inverter side of the cable in the normal rj45 cate5e T-568B cable arrangement? similar to the pics attached?

pardon my questions, how do i go about that? I was able to connect via node-red but its throwing up the error message below: "TypeError: Cannot create property 'fc' on number '1612780922024'" I have attached screenshot of a single input that i wanted to read from the inverter which is PV1 input for instance, i saw the address in the modbus register is 186 but not receiving any info when i used that

I am trying to get the functions working on my node-red, can i see a sample of what you added to solar_pv_day function node for instance?

I just get connected status even after modifying the cable arrangement, still not data, is there a way i should know if this is working? cat /dev/ttyUSB1 did you reveal any result

Yes I see the port on the pi just not getting data, let me now connect the cables as you have indicated. Thanks

Here is the link to the adapter, you do find it has A and B label and that's what I used, but from what i think you are saying. A is one end of the cable and B is the other end of the cable right? So 2,7 goes into rj45? And 1,8 goes into the usb? No driver requirement was indicated, it's possible it's a driver thing but first I want to be sure I have gotten the cable right.

I used the bottom diagram and then connected cable strand 1 and 7 to the usb. After connection,I ran cat /dev/ttyUSB1 on my pi but didn't get any response. Is there something am doing wrong?

I made a cable using this diagram but am not getting any feedback

Could you share pics of what your connection cable looks like? I am planning to get the attached USB rs485 converter as well, will it work?

Has anyone been able to get either of the webscraper above to work with deye/sunsynk wifi module adaptor? tried with no luck yet

Hello, Has anyone using either of those inverters been able to get the data on emoncms? I already have historical data on my emoncms (when I had MPP GK inverter) and I like to continue to log on the same emoncms which runs on my pi3+. I will appreciate explanation on how to achieve this? Do I use the WiFi logger or do I need to connect a different cable? Thanks

@Halcyonor anyone extracting data from sunsynk/Deye should kindly share
