  1. I got am I5 slightly older version for R1500 on Facebook, is way faster than a Pi3 and loads more space, 16gb ram and a 256gbSSD
  2. Hi TJ On the Modbus document that I have, it has the 417 Register marked as R/W so strange that it cannot be written to. Maybe someone else who has more experience with Modbus can comment, can only guess that there may be some other setting/value that needs to be changed to allow that value to be written. Good luck, keep us posted please. sunsynk_modbus - no chinese.docx
  3. I have been thinking of trying out a Waveshare RS485-Ethernet converter for my connection to the Inverter as it would allow me to move my NUC from out of my garage next to my inverter. Has anyone else tried one of these out? https://www.waveshare.com/rs485-to-eth.htm I have one lying around so will give it a bash in any case and see if it works better than the USB - RS485 adapter
  4. Hi Rhys It will all run on an Intel Nuc Box running HASS with the suplimentary apps installed. Home Assistant brings everything together and provides connections to most IOT devices, MQTT for direct current values in HA, Node Red for the Automations & linking to the Modbus connection on the inverter, Influx DB for storing all the time based data that it gathered by Node Red and Grafana for being able to format the data in a graphical way that is easy to understand and customise. The flows that Bloubul7 wrote have been updated and are being maintained by Jacauc on his Guthub page https://github.com/jacauc/SunSynk-NodeRed to include the feed from NR into the MQTT running on HA. It took a little time for an "average joe" like me, to wrap my head around, and a LOT of youtube videos on Node Red and Home Assistant, but in the end it is reasonably easy to understand the basics once you understand how everything links together. If you get stuck just give us a shout
  5. Will change that as well, thank you for the suggestions, am still working out how this thing works so all appreciated.
  6. Ok, so if I am understanding you correctly, by putting the names of the devices into the message parameters, I could cut out the 4 individual loops I have, one for each individual device, and replace it with one loop. Makes sense, thanks for pointing that out, that can be my next project
  7. I have a Sunsynk Inverter linked to Home Assistant running on an Intel Nuc so I can get the Battery SOC and how much power I am getting from the sun etc into HA. I am using Bloubul7's Node Red Flows to get all the data from the Inverter I built a Node Red flow to cycle through all my geysers, once one has finished heating up it switches to the next one (have three geysers and a borehole pump so they can't all switch on at the same time) Geysers are controlled by Ewelink/Sonoff compatible breakers switches which give power draw as well (so I can tell when the thermostat kicks out) Checks the time, power production and battery SOC levels before starting the flow & heating the geysers and sends me a Whatsapp when it is finished. I still have the timers enabled on the Sonoffs in case the Node Red doesn't run for some reason (wifi issues etc)
  8. My heavy load cycling flow is now working pretty well in my Home Assistant/Node Red setup and I have simplified my initial one to make it easier to maintain. I am using the EZ-Timer pallette in Node Red and all my sonoff devices are running in HASS to provide connectivity into Node Red. I am using Din Rail mounted Ewelink/Sonoff compatible breaker switches for my geysers & borehole which do power monitoring so I can tell when my geysers thermostats have reached temp & kicked out. These are available locally as well but are quite a lot more expensive (R720 each last time I looked) The node red flow checks production from the inverter to make sure I have power available and have charged the battery sufficiently, it will then cycle through the connected loads one by one until they have all completed their cycles after which it will send me a Whatsapp message to tell me it is completed. Still a work in progress but definitely getting there I still have my timers running on my geyser to just make sure I have hot water incase node red doesn't work for some reason (I have had wifi connectivity issues to the breakers from time to time) flows (11).json
  9. Watched the Youtube review last night, is frikkin hilarious, it got beaten by a guy on a bicycle in a drag race when it was loaded with 4 people!
  10. Hi D No settings on the Inverter. Are your Node Red flows working? Make sure you disable the write ones otherwise you will end up overwriting your Inverter settings. If you are polling your RS485 adapter correctly then it is probably something to do with the connection to the inverter. How have you got it connected up?
  11. Welcome tjs000 , I would suspect that it may have something to do with the format in which you are trying to write the settings. Maybe if you try the process the other way around, you may be able to get an answer from DEYE on how to set it up manually and then just write those settings back to the inverter. Firstly I would have a look at Bloubul7's Node Red flows and see if it currently reads the 417 registery settings (I would guess that it doesn't) and then rewrite the flows to just read the 417 registry. Store the setting so you can write them back when necessary. I would then try and set up the inverter manually to switch off the unused inverters, if you can get that to work then read the 417 registry again to see how the settings are changed with the unused inverters switched off and then save those settings. The 417 registry is marked as R/W so you then should be able to just switch between the settings by writing the settings that you have stored. Good luck.
  12. Thanks JaseZA, will try it out and see what happens Have also been working on one to manage my geysers and run them in sequence when there is enough solar. Seems rather complicated and I am sure that there must be a better way of doing the checks on power and battery. flows (9).json
  13. I want to use this as a base for creating another flow to cycle through running my heavy loads i.e. geysers, borehole pump etc based on very similar criteria but thought I should start off with something simpler so any comments on how I should go about doing that would also be appreciated.
  14. Hi Guys I am a total novice and only just getting into Home Assistant/Node Red I am looking for comments/suggestions on my first Flow which I created to switch my pool pump on based on: Time - to run starting at 09:00 Check Solar Power being generated - more than 2000W Check Battery SOC - great than 50% Once my pool is on, check Power & SOC every 10 minutes and switch pool off if not meeting requirements and then retry every Time - turn off at 15:00 and then to start the whole process again at 09:00 the next day. flows (8).json
  15. There is a lot of discussion on this board of linking up the Inverter to Home Assistant using Node Red and the Canbus connection on the inverter. Works like a charm.
