June 27, 20233 yr Hi Guys Please can you help with a couple of questions concerning using the ESP32 Dev ( Slipx06) board to get your data? 1. After Loading ESP32 with Esphome , do you upload the Slipx06 ESPHome-8K-Sunsdynk.yaml file onto the ESP32 or do you add the file to your Home Assistant under the Config ? 2. I watched the youtube video but not clearly explained concerning the files etc. Nothing about Adopt the device etc. Nothing concerning about files and if they get uploaded or added to the configuration file. 3. This is my Log File: NFO ESPHome 2023.6.2 INFO Reading configuration /config/esphome/esphome-web-cf06a0.yaml...

June 27, 20233 yr That's an ESPHome config so you need to copy the contents of the yaml file into your esphome device. Keep your own wifi settings. Use the EDIT button

June 28, 20233 yr Last time I got CRC errors was when to 2 wires got too hot from the solder and kinda melted together, but some of the values were actually coming through. I cut of the wire and soldered again and my issue was gone. I see plenty people are removing their terminating resistor between A and B, that has never been the case for me. Usually when I get errors this shows me something has poor contact. All I can say is that it is normal to struggle a bit. I once spent a whole afternoon de-soldering(and burning my finger) and testing, scratching my head, re-doing... and it turned out that the RS485 module was actually dead. I started measuring resistance over the various points and compared with a working module. I also noticed later that the little red light was not lit Thus far 1 out of the 14 I ordered was dead. Good luck Edited June 28, 20233 yr by iiznh
June 28, 20233 yr Author I have a extra board, I try that one and will not remove the resistor as shown in the video. I am using the those small female plugs. I try rather solder the wires and see if that makes a difference. Thanks for the advice
June 28, 20233 yr Author @iiznhCan you tell me why am I get a warning when using GPO 04 ? ( WARNING GPIO4 is a Strapping PIN and should be avoided. ) ? Is this normal etc , everyone else is using it Thanks
June 28, 20233 yr @Vaughanza GPIO4 is used while the processor boots up, if you pulled it high/low (cannot remember which but I think it was low) the processor will fail to boot. Been there done that, thought I killed my board. Unsoldered the pulldown resistor and hey presto the ESP started booting again, I think it was during my smart relay build that I used to dump excess power into the geyser It is normal to get a warning message. It is just a warning In your case you are using it for flow control only after the bootup finished so it does not matter. Maybe post a photo of your module. I also battled initially, that is precisely the reason why I built a ready made module for Deye inverters. People want to focus on making their homes smart, not on soldering and studying the specsheet of espressif processors Edited June 28, 20233 yr by iiznh
June 28, 20233 yr Author @iiznh I have managed to get Data from the Sunsynk 8k inverter but the reading says Unknown with all the sensors. The sensor name comes up etc but the actual reading of the sensor says Unknowm, What am I doing wrong or setting Thanks
June 28, 20233 yr 15 minutes ago, Vaughanza said: The sensor name comes up etc but the actual reading of the sensor says Unknown The only time when I see unknown is when I am flashing a new version remotely and rebooting the module (effectively it stops communication and drops off the network) once it is rebooted and joins the network again it takes a few seconds and all values are showing again. Try pinging the IP to makes sure it does not drop off the network from time to time (I think I solved this by disabling power save mode)
June 28, 20233 yr Author Thanks to everyone for the help, eventually found the problem. Had to connect 2 and 7 ( rj45 wires ) to A & 1 and 8 ( RJ 45 ) to B. As soon as I did this, data came through. In the video it does not say anything about connecting 2 pairs . Thanks again and particular @iiznh , appreciate it.
June 29, 20233 yr @Vaughanza Great! Glad to hear. With your inverter now part of your smart home you will hopefully give less business to Eskom and gaining better return on investment on your solar system! How many hours would you say you spent on getting this ESP32 project from discovery to getting values showing up? Just as a reference for other people? It probably took me a good 2 days to get my esp32 module working even though I already read all the threads on the topic (incl the time I was looking and trying to understand which parts would be the best and what the differences are between them) My journey over many months: I started with the node red flows that I ran for quite a while on a Pi Zero (but it was going offline frequently due to the pi zero dropping off wifi) Installed a wired access point close by with strong wifi, but the pi zero was still not happy Then moved my home assistant server (running on raspberry pi 4) to the inverter and installed the kellerza plugin (still had network issues, home assistant does not like to run over wifi, you need a wired network point, at least the plugin worked brilliantly) I tried the esp32 route and for the first time my setup was stable, had 0 disconnections and everything finally worked the way it should. (Rasp Pi moved back to router) I moved my home assistant to a VM on my home server because I integrated my cameras with Frigate (and automated my security) and needed something with better storage for video footage

Hi @Vaughanza It isn't necessary to connect two pairs, once pair works.

removed from send queue The entities show up in HA, but the values are Unknown: The Inverter Connector Wiring: ESP Pinout Diagram: ESP Wiring: RS485 Wiring: DI>TX, R0>RX, RE>P5 I've tried it with both 2 and 7 to A 1 and 8 to B and only the single pair. I have 2 RS485's one with R7 and one without, no joy on either! Any ideas why its not gathering data?!?!?!

Is your inverter set to modbus address 01? I also suspect that you are building the wrong firmware for you 5KW, the registers differ alot. Sun12K looks like the 3phase But even with the wrong messages the inverter should be responding with data, it will just not make sense Edited June 30, 20233 yr by iiznh
June 30, 20233 yr THANKS!!!!! I swopped A & B around, but that didn't work. What did work was the VCC cable was unplugged and it started pulling data! When i connected the VCC again it stopped! Now the question is, do I need the GND and 5V connected on the RS485? Well I answered my own question. If I disconnect the GND I get CRC errors. This is what it looks like now: ESP32: RS485 Front: RS485 Back Also I need to setup the correct registers and then I'm all good! Any idea who's repo I can use for the Deye 5.5KW? I'm doing this for a 8KW next week, do you think the same connections will work? Thanks again for the help!!! Edited June 30, 20233 yr by Ar135

You allways need GND/Neg this is the reference point. 18 minutes ago, Ar135 said: Any idea who's repo I can use for the Deye 5.5KW? There are various open copies floating around... but imho they are pretty much a verbatim copy of the nodered flows, lots of things need fixing on them, maybe @slipx fixed some of the issues in his version? I haven't looked in months since I built my own version, maybe I'll opensource it once recouped the sunken costs I believe there are links and code snippets in this thread
July 1, 20233 yr @Ar135 Most inverters seem to use pretty much the same modbus register, the only significant differences are between the 3-phase and single phase inverters mostly on the grid & load side for pretty obvious reasons. You can use the files from @slipx's Github page and he has a file for the Sunsynk single and 3 phase inverters, that works on the Deye's as well. For interest sakes, there is a standard for inverter communications that a lot of the manufacturers, include DEYE, have signed up for https://sunspec.org/sunspec-modbus-specifications/ .So it is not only Sunsynk and DEYE that these integrations will work with.

Was about to give up but disconnecting the VCC I managed to get readings from the inverter (Sunsynk 5kW).

As soon as I did this, data came through. In the video it does not say anything about connecting 2 pairs . Thanks again and particular @iiznh , appreciate it. Thanks for this! This solved my issue too!
