  1. I have a Deye, OEM Sunsynk. All the Sunsynk guides I followed worked 100% without needing to convert. The Modpus protocol sheet also 100% compatible. The only difference I know of is the physical enclosure and the menus / icons on the little lcd touchscreen... Innes
  2. Hi everyone, I still have not figuered out how to write (change) addresses using Node Red - I.e. enable / disable time of use etc. Reading info from inverter using @Vassen info works great but even after looking up the relevant protocols I am still missing something. Anyone able to post the flow? Thanks
  3. Thanks for the answer Bloubul. I understand how Modbus works now. I am able to get information on my queries and also push this info into Influxdb now. My only unanswered question is how to write to the inverter? I would like to monitor the load shedding schedules and enable / disable "time of use". I use Node Red and Modbus Write / Modbus Flex Writer but cannot seem to get all the info / syntax to the particular address correct. Thanks
  4. I used 192 "load frequency" and it seems to work. Thanks for pointing me in the right direction @Achmat
  5. I'll give it a go and revert. Thanks for quick response!
  6. How would you measure / report on power fails / load shedding? I can monitor "Grid side L1 power" (167) that reports correctly that there is a 0.00W supply. If however the PV panels supply more than needed this also goes to zero, really messing up automations as there is not a power failure but at a state that power from the grid is not needed. How would you monitor power fail (i.e. no incomming power from grid) vs "no supply needed as there is enough" ? Secondly: How would you write to the registers? I use node red and use to read: (example reads 248 "time of use" s
  7. Thanks for the response Justin, I managed (with lots of help from a friend) to get data flowing. Using a different Modbus reader (a PI Hat) and Node Red Flex Getter nodes. All starting to come together. Innes
  8. I am not sending anything - sorry I am a real noob on modbus. I sounds like I need to send a request and will then get an "answer"? Not sure how. I was under the impression that the inverter will "stream" info automatically and I wil then decode and use what is needed / useful. I can send text via nodered as a test - what do I send though? Please excuse my ignorance - I need advice. Innes
  9. Hi everyone, thanks for a very interesting thread. However I have tried everything but cannot get comms from the RS485 port. 1. I made a cable using Justin Schoeman's diagram (bottom picture) 2. I am using a RS485 to USB TTL (https://www.communica.co.za/products/bmt-usb-rs485-ttl-converter-ftdi) 3. Plugged into a RPI3 running the Modbus TCP Gateway (https://github.com/3cky/mbusd) I am not seeing any RX/TX leds flashing on the TTL converter so I am assuming it is not sending anything. The inverter is connected to a Pylontech 3000 on the CAN port and I have a Sofarsolar

  11. Hi this is very interesting. Awesome work! @Bloubul7 can you possibly share your Node Red flows? Thanks a lot
