There is an on-screen menu for configuring the RS485. Hold down the OK button for a couple of seconds until it says “Basic Parameters”, and then you can navigate to RS485 settings. (SPH10000-TL3)
Hi Christoffer, yes, I am anware of this settings. We checked with Plawa in an offline communication that his settings is “unused” (other are ShineMaster, VPP and Meter2). For me having set “unused” does not help either. Will investigate furhter over the weekend but seems I am stuck with no ovious reason.

Hello there, im going to buy a SPH3600, i can see that you have export to grid information, is that provided by the GroWatt inverser or dou you use something else?
Thanks
Hi, I got the first MAX3485 hit I got on Aliexpress (the red one with angled pins)…
The graph is just the custom mini graph lovelace card, nothing special
That is provided by my inverter but I can’t obviously guarantee it will be provided by yours…
hi.
This is the esphome code for Growatt SPF 5000 ES.
I’m using a d1 mini with a ttl converter.
This code allows changing the parameters of the inverter. BE CAREFUL !! (The worst thing that can happen is you have to configure the inverter again.)
The code has all the configurations that I was able to find, it doesn’t mean that they are all here.
The names are the factory names, I don’t change anything.
Thanks to all.

So cool! Thanks for sharing.
I will give this a go. Is there no youtube tutorial about this? 
I don’t think so.

And thanks to you I now have immediate local control over the parameters on my SPH 10k-TL3 BH-UP I was most interested in:

Tested, works exactly as expected… this means I can finally build proper logic around low/high tariff use from grid (i.e. I can charge the battery at night using low tariff and then use it during high tariff period - that alone can save quite a few $ around here), be able to prepare for a planned outage and eventually when the market catches up and we can actually sell for spot prices, I can do that too…
Thanks!

This is really a game changer for the battery mangement. I’m going to do the same, using the production forecast I will charge or not the battery, and use the low tariff to charge wen need.
I’ve been waiting for such a solution for a long time, I’m testing it and it works fine.
Thanks !!
Hello Pavel,
do you have found a solution for this problem? Seems i have the same problem.
Greetings
Izi1
Thanks for info. I have ordered two types of converters, now waitng for them to arrive and test.
Until then i am stuck with standard integration with data update from server at 5min.
Hi goodmorning,
Thanks for sharing this.
I read the most of this thread and have ‘your’ version up and running now.
Original Shine WiFi-X stick and flashed with the yaml.
Got rid of the sensors I didn’t have and running in HA now.
Working with the MIC 3000 TL-X.
Thanks to Chris Huitema and Wilbert Verhoeff for helping me pointing in the right direction.
Pieter, what If you add external power to the stick?
5V ( USB Power ) soldered to the board?
Hi izi, no, I did not manage to get it working. Tried two different boards (esp8266 and esp32), two different RS485 converters, different pins (1-5, 4-5), different RS485 settings (VPP, unused) in all possible combinations, but nothing. There is no data coming on RX pin (LED does not blink). I will try the code from candidotsa but I am afraid it will not work. Probably the RS-485 connector is failed or the communication is somehow disabled.
Hi. Jumper You’re rs485 connection is RJ 45? Did you tried the pin 7&8? 7 for A and 8 for B.
Hi caro7372. The code is the same from the 5000es?
I used the next one as found above:
You can try to connect your converter and ESP32 to Easton SDM 630 smart meter if you have that installed and flash the ESP32 with Eastron SDM code. You will see some of the parameters provided by Growatt from there since the invertor is taking data form the smart meter. Here you can find info:
I did not try it myself, but i am planning to do it once i will receive the RS485 to TTL converter.
