May 27, 20224 yr As per the subject: I would like to know if anyone started a project of collecting local data from a SunSynk WiFi Dongle? I am sick of server-outages and lost data and am thinking of either hi-jacking the traffic (on my router) to SunSynk's cloud storage or cracking open the dongle and re-programming the NCU chip... My Question: Has anyone thought or started something like this? regards Aubrey (aka cyber7) ps - as an afterthought, this could even work for that "other" dongle we all got with our systems for free Edited May 27, 20224 yr by cyber7 make the circle bigger
May 27, 20224 yr Author ps - thought about it and it will be easier just plugging a "serial cable" into the inverter...
May 27, 20224 yr When you say the "Sunsynk dongle", are you talking about the new Sunsynk dongle or the older Solarman dongle that plusg into the Sunsynk inverters? I don't know of any projects using the new Sunsynk dongle's as yet There are a number of projects using the Solarman Dongle for connection via Wifi to Home Assistant. https://github.com/StephanJoubert/home_assistant_solarman Otherwise you can bypass the dongle altogether and connect using the RS485 port on the inverter with a USB/RS485 converter to you Home Assistant box. https://github.com/kellerza/sunsynk or you can use the Node Red Flows created by @Bloubul7
May 30, 20224 yr Author Jup, but it is going to take just one small upload to overwrite the firmware on that nodemcu
May 30, 20224 yr @cyber7Which wifi dongle are you talking about, the Sunsynk App or the Solarman App one? Would be useful if someone could work out how to query readings & write inverter setting changes directly to the Sunsynk dongle.
May 31, 20224 yr Indeed there are loads of information regarding the Solarman Logger - However, info on the new Sunsynk Data Logger seems impossible to find. If @cyber7 was talking about the newer logger, then please confirm and we can utilize this thread going forward to explore the possibility of reading and writing data to the Inverter via the Sunsynk Data Logger. This is what the Sunsynk Data Logger looks like: Edited May 31, 20224 yr by valienté

June 1, 20224 yr Is an ESP32 MCU, would be cool to reflash with ESPhome and pull all the data from the inverter that way.
June 9, 20224 yr Author If you look at the board and the data-sheet - URL TO PDF - you will see only a few pins are being used... Should be able to break into the board quite easily by running wireshark and looking at the data coming out of the network...

I briefly used Wireshark back in the day, but that only gave info on the Device it was running on... How would one get the info from the Logger running on the network?
July 16, 20224 yr To confirm do you want to pull the firmware from the nodemcu, or just utilise their API? It might be easier to just write some HA integration which directly talks to the SunSynk cloud APIs to pull the data. For the SynSynk API see below.

August 16, 20223 yr Good suggestion @frankie that would be pretty cool @kellerza Did a similar Integration for HA for the Solarman Dongle, not sure how similar they are, is way above my paygrade lol https://github.com/kellerza/sunsynk Oops, sry, the KellerZa integration is via the RS485 port. There is one using the Solarman dongle, just need to find it Edited August 16, 20223 yr by Sc00bs

September 18, 20223 yr So the "Sunsynk Data Logger" is basically this product from e-linter ? inteless.com, minus the RJ45/Ethernet http://e-linter.com/smart-energy/goldfinch https://doc.inteless.com/page/p/goldfinch/manual/db9/index.html According to the documentation, the comms between the inverter and the Data Logger is RS-232. I'm not entirely sure what protocol the RS-232 port on the Sunsynk inverter presents, but I'm going to guess it's probably ModBUS over RS-232. If someone can find a binary blob for the firmware of the dongle, I can probably take a stab at reverse-engineering it. Solarassistant.io seems to be capable of supporting it over RS-232 directly. Edit: Seems like this document in this thread confirms that it's modbus over RS-232 at 9600bps. The cloud API stuff seems like a pretty closed ecosystem, other than the interesting API information that @frankie has posted earlier. At worst, using those API's might be the best way to get the data logger into Home-Assistant, but I'd prefer something that doesn't depend on inteless's cloud API. @frankie did you sniff the application traffic on a phone to get a hold of the API calls ? If so, nicely done. The image that @Sc00bs posted suggest that on the top right hand there are pads for T/R/G which I would assume is the ESP TTL Transmit/Receive/Ground, so in theory those could be used to flash it. The device's web interface itself doesn't offer more than upgrading software or changing WiFi SSID. There doesn't appear to be any ports open other than http(80). I might just try and give it an ESPHOME image and see if it's willing to upgrade to a new custom firmware. Edited September 18, 20223 yr by TheRoDent

Whilst it would be great to get this going, as a home-brew, I just took the plunge and installed @SolarAssistant on a Raspberry Pi, with a USB-RS232 adapter. Simplest, easiest integration I've ever done, and solarassistant.io is superbly slick. Well done. I now have a useless Sunsynk Data Logger, which I shall attempt to brick at my own leisure using ESPHome. Edited September 18, 20223 yr by TheRoDent

Solar Assistant currently doesn't do that
October 3, 20223 yr I pulled the firmware off my dongle, which looks slightly different to the pictures that were posted earlier. My ESP32 is a RISC-V based C3. I'm happy to share some of the partitions, but a couple of them have my home WIFI details embedded in them. I had a go at reverse engineering them with Ghidra, but ran into the problem of specifying the memory map, which I am not quite sure how to do. But yeah, I'd be quite keen to get an ESPHome-based firmware running on the Sunsynk dongle. While kellerza has done a sterling job with the sunsynk plugin, I'm trying to move away from the MQTT server towards native ESPHome protocol. If I need to do any firmware updates, I can always flash the original firmware back, since I took a copy. Edited October 3, 20223 yr by RoganDawes

This is what the Sunsynk Data Logger looks like: Got a surprise the other day. Previously sunsylk issued a magneto data logger with their inverters (looks like it) . We could not understand why we can not find the client on the sunsylk app. Then saw they gave us a magneto data logger that can only work on solarman. I also ordered an add data logger 6mnths ago. When we wanted to replace the magneto data logger that was issued 2yrs ago with the installation we found out they gave us again a magneto data logger. Still gotto contact the supplier. I want to know how could they sell a magneto data logger to us if the order stupilated a sunsylk dongle. Anyone else with the same problem?
October 6, 20223 yr I can provide a wireshark capture of the logger traffic, if anyone is interested to try and decipher it. At the moment I'm pulling the modbus data directly from the inverter, so I'm not really motivated to use whatever the logger is pushing out.

At the moment I'm pulling the modbus data directly from the inverter, so I'm not really motivated to use whatever the logger is pushing out. I’m running OpenWrt on my router, so have wireshark captures already. I think what I need to do next is capture the serial traffic and the tcp traffic at the same time, to see what the dongle is adding to the connection, or if it is doing any protocol translation.
