i have 2 leds on blue and red. still not working. you need to keep the bridge between gpio0 and gnd still insert when you upload the firmware?
I kept them bridged

Did you sort it out @Maarten1 ?
I’m also trying to flash my ShineWIFI-S but having a hard time getting it into boot mode and getting the same message as you mention.
If I short the GND and Gpio0 pins the green LED stays off and red and blue on, is this correct?
no i dont get it working.
here the same with the leds. the green led stays off red and blue ar on
I mixed up Rx/Tx and was able to flash it now using esphome-flasher.
Did you find a way to integrate the upload to PVOutput in esphome?
There is a way, but having it done by home assistant made it go down on my priority list
Well last night i flashed both of my shine sticks where flashed without any problem
i have a growatt 15kw 3phase model and a growatt 6kw 3 phase model.
But they just started and are producing, just got no outputs ;(
i used the script from @chris.huitema for my shine sticks.
When i check the webserver/log i can see this :
any ideas what to try ?
looks like the pins are mabe different on my board or ? it can’t get any data and just a few sensors from pv1 only.
Looks like it has no modbus comms to the inverter. What is the exact model number? And is the dongle the WiFi-x
thanks for the fast reply,
the models i use are :
growatt 15000tl3-s
growatt 6000tl3-s
I have a picture of the board here , it has a esp07 on it.
This is the S. Try change the baud_rate to 9600 of the red module.

The dongle is different, but as far as i can tell they still use the same pins GPIO1 and GPIO3, and Modbus Address 0x1
Did you set the logger baud rate to 0? to prevent the logging going out through the serial port?
1 Like
Ah i might have one of the earliest versions then i guess.
I did set it on 0 to prevent it indeed like you have in the config you posted.
Now it is uploading as we speak with baud rate set to 9600
thanks both
ah yes… just went back up through the comments above… and noticed the same thing, its the baud rate
seems to work now 
it does give a red error in the log file and not all the info is loaded yet.
And the total lifetime output is a bit onj the high side, same as today, don’t get me wrong i would love it if this was true haha
Edit: i am trying to change the multiplier untill i get values that are more real time.
Are some of the sensors not supported now with this script like the AC output current? these did use to give something in the growatt logging app.
edit: well ive been busy from this morning till now but can’t get the right multiplier formula , thought i had the right one calculated but an hour later when i checked the total in esphome and total on the inverter it was way off.
Also tried the standard growat script that can be found on the esphome.io page, this does give the values for the phases how much the voltage it etc.
But there i miss 1 phase.
Also the total day and total output is not visible there.
So for now this is all not fully working

You will need to check the registers for your inverter and which ones are actually available
Search for your inverter model and modbus and you should find a pdf. Have a look at my notes above about the word and double words to make sure you get the right size
Most values should not need scaling except a few that are divided by 10
It seems to work now slowly ., thanks all for your time
I am having trouble to get values from the rs485 interface, hope somebody can help.
Maybe i am doing something wrong.
I have a growatt inverter MIN-3000TL-XE
connected the wifi growatt dongle which does a upload to the growatt siet, that is working fine.
But i also wanted the data from the inverter in Homeassistatnt, so i also have attached a rs485 module connected to a NODEMCU.
I used the code earlier in this post:

Buti don’t get any values from the inverter.
i don’t have connected the flow control pin.

Can somebody say what is wrong with this information?
i think you have the ShineWifi-X. your baud_rate: should be baud_rate: 115200
No ik have no shineWifi.
I have a Nodemcu with esphome flashed on it, and an rs485 module. I have tried 2 different rs485 modules. (RS485 to TTL) and (HW-97)
Als tried baurrates 9600 an 115200
both the same.
Maybe something wrong in the registers?
