Hey Scoobs, im based in Cape Town sadly !!! any chance of a video conf or Whatsap connection would be HUGELY appreciated, really keen to get this project finished

Still battling for comms Scoobs, any advice you can give me from the above !! Hugely appreciative

Thanks Scoobs Not entirely sure as to which usb setting I should use, I think S3 was auto selected, I then selected S0 but this returned the same error, I then tried the one that stood out in syntax namely /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 This also failed with same message The hardware list seems to have the same entries they all seem to be appropriately initialised and have the same sequential values the only one that stands out with populated data is this below where there is a clear difference between ttyS0 and tty USB0 ? Strange I have swapped the various usb ports on the NUC with no alteration I then removed the ground connection and tried again with no change I then went back into the mosquito broker and double checked the usernames and passwords as im using it for my paradox alarm integration, with the following certificates and private keys...could these be an issue ? Thanks a ton

Thanks again for all of the help here, a big request for assistance here, so I am still unable to communicate with my 5kw sunsynk, here is my sequence of installation: Purchased the USB to RS485 Converter Cable, 4 Pin adaptor as recommended Then wired a rj45 according to T568B spec as follows: Then wired the converter according to the table in the T568B table as follows: Orange/white to B Orange to A Green/white to Neutral Went through the Youtube installation process, installing the add on etc. As im already running Mosquito on my paradox install I used the same username and password there Used the following settings in the configuration Then plugged the RJ45 into both the BATT485; the 485 port and neither are generating any comms the only other option appears to be the BMS CAN port which I also plugged into and all results were the same all of these returned the same result as pasted below. The log file fails at the initial comms: 11:07:41 INFO Added hidden sensors as other sensors depend on it: Rated power, Serial 11:07:41 INFO Connecting to tcp://homeassistant.local:502 11:07:41 INFO PyModbus 3.4.1 tcp: homeassistant.local:502 11:07:41 WARNING Failed to connect Multiple exceptions: [Errno 111] Connect call failed ('172.30.32.1', 502), [Errno 111] Connect call failed ('172.30.232.1', 502), [Errno 111] Connect call failed ('192.168.68.148', 502), [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument, [Errno 22] Invalid argument 11:07:41 INFO ############################################################ 11:07:41 INFO Could not connect to tcp://homeassistant.local:502: 11:07:41 INFO ############################################################ 11:07:41 CRITICAL This Add-On will terminate in 30 seconds, use the Supervisor Watchdog to restart automatically. I have also been through as many of the online posts to try find out the reason for this but to no avail, this is my second round after getting a similar outcome on the ESP32 option. I have the usb adapter plugged directly into an intel NUC running HAOS which currently runs the cloud (nodered) sunsynk connection with slow update and no ability to write settings back to the inverter. I doubt this could be a conflict. Somehow I suspect that it could be 1. the port settings in the config ? 2. need for separate driver install in HAOS (never outlined in any docs) ? 3. Possible faulty RJ45 termination although these were the push through type and I triple checked them before trimming ? 4. Possible mosquito username/password issue but seems to fail at base comms and have copied directly from the Mosquito config. 5. Other modbus settings I could not figure out im pretty sure Really appreciate any input I can get here Thanks Dunc

Dont know why I cant reply to individual posts but massive shout out to Scoobs for the offer to come out and KellerZA for this great project, im blown away by the level of work done for the community.... I haven't managed to get ESP running but part off these projects are learning HA and some microcontroller logic/programming so went ahead and bought the RS485/USB adapter, seems far simpler, going to plug direct into my HA pc and see where I go from there. HA has been an unbelievable find, have it running Paradox, ezviv cctv, Sonoff (obviously), now ESP32 controllers, Tuya smart DB switches (which is a truly awful integration and battles with Wifi comms from my main panel but sub DB running pool pump is solid) Have a 5kw running 14 x 450 panels w 10kwh batteries, system is maxed out and now with predictive solar I can easily use all the available power on sunny days for pool pump and second geyser. Recon I can probably get over 30kw per day on this system, I do monitor voltages and current rates to make sure im not over safe limits...again HA is incredible for this. Thanks again

Quick one Has anyone managed to get the sunsynk (not solar man) dongle to work ? I have been down the esp32 route and cannot get proper comms, I would like to set this up as it looks super keen. I have a ss dongle that's about 14months old and do see that it states about that this does not work with the "new sunsynk dongle" do older ones work or am I just reaching here ...;-) Thanks

Just saying HI, planning to find some key guides here main one will be where to find the best priced mini PC
