Open McAndersDK opened 1 year ago

McAndersDK commented 1 year ago

Am i missing something or dont this repo have info about how to connect the board to the genvex? :) I have been looking into the following: Optima 250 and Genvex GE Energy 2 The genvex GE Energy 2 have the following connectors on the mainboard to the Optima 250: L2 image and from the genvex connect documentation I can see the pin outs for the Optima 250: image but im still not sure what to connect to what? :)

So far I have found this: for a nodemcu-32s Board <-> Optima 250 5v <-> power module <-> 23 ground <-> power module <-> C1 rx_pin: GPIO16 <-> ? tx_pin: GPIO17 <-> ?

Did you get this working?

McAndersDK commented 1 year ago

no not yet.

Well... you need a modbus module. ESP32 -> Modbus module -> Optima Easiest is to buy a complete module. I believe this will work, cutting one end of the RJ45 cable and connect the wires to the optima display. Not sure if it can power the device from the optima display, or if power using the USB port is needed https://ustepper.com/shop/home/18-esphome-modbus-module.html https://github.com/heinekmadsen/esphome_components/blob/main/components/genvexv2/Betjeningsvejledning_Modbus_Communication_OPT250_V3.1_20.11.14_EN.pdf
