Yes, the Esphome Modbus specs do say an ESP32 is preferred although an ESP8266 should work too.

https://esphome.io/components/modbus_controller.html

busy trying to flash my esp32 with esp home... keeps on failing, where as the esp8266 (slightly smaller chip) went easily, this is on my MAC, did try on a Windows box also, same issue with esp32. I'd prefer to use the esp8266, it being a bit cheaper... but if it's going to cause problems then I'll have to figure out how to get the esp32 working... ps I did use arduino to flash a simple getchipid onto the esp32 and it worked (from MAC).

can add the esp32 shows a red light while connected where as the esp8266 showed a blue.

hmm, let me see if i can find a distro of esp home that i can flash using arduino

ideas ?

Grafana 9.2.3 Canvas Visualizations can do a similar thing.
https://grafana.com/docs/grafana/next/panels-visualizations/visualizations/canvas/

system32, any chance you're good at Grafana and/or SVG... 

I got a sensor that measure water level of a water tank, and would love to input a percentage full and have it visually display it in HA, minnyou I'd love to be able to show the same JoJo tank in Grafana and show / water level based on a input %.

"My" ESPHome code, which is a combination of others work before me.

But I believe the Deye registers are completely different?

Hi Corne.

I'm trying to figure things out. eventually got esp home installed on my esp32 using the esphome-web-tool.

I'm guessing I need to get the above code onto my esp home now ?

do you have matching HA dashboards ? and/or Grafana?

I will use Sc00bs esp32 -> RS485 dev board wiring to connect the R485 to the esp32.

Please help, never used a esp32 before, nor esphome.

PS: inverter is a 5Kw Sunsynk...

... ok I'm slowly working through the 13 odd pages here...

I got a esp32 that I've been able to flash with the demo image using https://esphome.github.io/esp-web-tools/

but now i'm lost... discovered you can't load you devices after the flash, it seems you include your devices in the image you flash.

Can someone help.

have a sunsynk 5.5 Kw inverter that I want to integrate with HA using one of these examples.

@system32 @Sc00bs  Thanks for confirming, I thought as much. It would be nice to have the added safety of having the geyser on non essential, but i suppose it is not necessary and also the reason i am going for an 8kw instead of the 5kw so i can add more panels at a later stage. 

hi, so I'm helping a friend n his Sunsynk atm, but I have a Victron, but how I did it...

Put my Geysers and stove on the non essential, but they are connected to the db onto a contractor, which then connected to a isolator.

I use 4 channel sonoff tasmotized with which In control/ open/close the contacts points. so my load is carried by a contractor, I control them via sonoffs. The sonoffs themself are on my essential circuit so they always powered.

with this setup of contractors and sonoffs it allows me to intelligently control my geysers and pool pump via timers in HA or NodeRed flow.

Excellent work i have my setup all have gone with Pi zero sending Data to HA on pi 4b and all looking really good.
Now with the load shedding animal i need to be able to change my charge settings on my Sunsynk Inverter similar to the settings that you can change on Solar Assistant 
A lot of work that i still need to get going on grafana but i have some graphs working lekker thanks to Scoobs and Bloubul 7 

I just need to figure out how i can change these settings on my inverter and if possible have the schedule changed automaticlly with these hectic schedules we have at the moment but for now if i can just change it using Home assistant or Nodered and write back to the inverter 



 

Farcus.

I'd be keen to know how you did this on a Pi platform, I have some lying around and would love to understand/know, might be easier for me as I know them vs the ESP32 platform/builds.

please DM me.

Hi Folks,

Been building the ESP32 and RS485 project up to connect to an inverter (I am UK based).

Anyway bought an ESP32 DEV board and this TTL > RS485 board

I've wired them up as described and followed the instructions. I can now see the ESP board in Home Assistant fine but when I click on it there is only 1 entity which is "ESPHome Web 137a18 Firmware".

I have tried the following:

• Removed the R7 resistor
• Tried a second TTL > RS485 board
• Tried a second network cable
• Reversed the network cable wires that are in the TTL > RS485 board
• Remove the plugin fully (Including removing the old directory left) in Home Assistant
• Flashed the board a few times.
• Re-seated the RJ45 into the inverter 
• Reheck and re-soldered the wires again 

When I check the logs I only get a few lines around the setup see the attachment INFO attached ESPHome 2023.7.1.txt (I have hashed out the MAC), there is no data coming from the Inverter other than the output.

I am not sure what else I can do.

Any help I would be greatful.

Regards Ivan

Not sure if this will help but I found that I initially needed to add just the ESP32 to HA with nothing connected it. Once it's added to HA and online, add the rest of the YAML code to it and upload it wirelessly.

Once this is done, connect the TTL > RS485 board to the ESP32.

Then try connecting it to the inverter.

Hope this helps

When you say the rest of the YAML code, which part are you referring to please?

I'm not sure what Inverter you have (assuming it's an 8KW Sunsynk as this is where you've posted but this is the code I'm using courtesy of @slip

As he is using a Nodemcu, you'll need to change this plus Wi-Fi details etc but everything from the captive portal should be copy and paste

esp32:
  board: esp32dev
  framework:
    type: arduino

OK so I have the 5.5kW inverter and I have also change the board to the one listed. I have wired it up like the diagram and adjusted the following config based on the PINOUT diagram, I am much closure but not yet across the line.

I can see lots of logs coming out the ESP32 unit now which is a step in the right direction.
 

uart:

id: mod_bus

tx_pin: GPIO17

rx_pin: GPIO16

baud_rate: 9600

stop_bits: 1

 

modbus:

id: sunsynk_modbus

flow_control_pin: GPIO4

Hi thanks for the advice @XAB@XAB it turned out to be exactly this. All the guides say top left port and it even says RS458. I came accros that 2 in 1 port and thought to myself there is no ways as mine is has a dedicated RS458 and its on the top left. Anyway when reading @fStofs post I thought just maybe and the plugged out battery cable and it just worked. sorry I couldn't reply been working. Made myself a 2 in one cable for the time being and have ordered one of those rj45 splitters. Just need to get the rest of the dashboards graphs working as some of the sensors have esphome in them.

[XianZA]

Hi @georgelza Im also new to esp32 but once you do it correctly one time its starts to make sense and become quite simple. I got a blue led on my esp32 when using GPIO2 and GPIO3 trying to troubleshoot.. But the esp32 supposed to be red led when its working. Make sure you using the top middle port marked RS458/CAN. If your battery is in there just unplug it to test. I also struggled the first 2 weeks as the esp did not have full wifi. Post some pics so we can see at which step you stuck at

Edited August 13, 2023 by XianZA

[georgelza]

so some figuring out.

esphome web tool will and can work... you just have to press the "boot" button on the esp32 when you click on the install option in the web tool... 

what makes it more interesting... doing this for a friend, so trying to figure out as much as I can at my house, now to go and install the physical bits at his, allowing me to return to my house to then remotely work on his HA deployment.

eventually figure out that I install ESPHome as a add on onto my HA. I then flash the esp32 and tell it to register with the local esphome running on ha. at that point I can add the yaml in esphome running on my HA to then do the sunsynk config.

need to relook at various bits of yaml i copied to make sure I copy/past the Sunsynk 5.5 kW yaml and not the 8.5, as they are all over the sight... just keeping track of the things i made notes off.

about to pop over to friend, see if i can do the physical on prem bits.

will "remove" the R7 resister also, as it seems it's a common across the board best option.

Hi @georgelzayou getting there. I also looked at all the different code. I never saw a difference between the 8kw and 5kw. Eventually I settled on slipx version as his seems to be the most versatile and upto date. And he has intergrated certain things from other peoples code but most importantly hes got some things in that others dont have. In the end he has a 8kw and I used his code just fine on my 5kw

 

[Ivan_E]

Hi Folks,

I am well and truly stuck. I have the the setup by @Sc00bs in his video https://www.youtube.com/watch?v=VxhmD2GAJv4", not sure if I have to fully remove this before I start with the ESP32Dev \ RS485 build?

I have the SunSynk 5.5kW inverter plus batteries. I have check the wiring and can confirm I have followed this wiring diagram to the letter.

I have installed the drivers from the ESP website and can see the ESP module when I plug it into my Windows PC on serial port 7. 

In Home Assistant I add the ESPHome add-on and then prepare the ESP module for initial setup where it joins the ESP module to my Wifi network, this is sucessful, I then click on Adopt in ESP add-on plugin.

I then remove the module from the USB port and plug it into a USB powersupply. After a few seconds the Add-on in Home Assistant shows as online.

I then add the device in Home Assistant under Device and Services.

I go back to ESPHome and click edit, to view the YAML that is installed on the board, I then copy in slipx06's code and change the  board: esp32dev, I update the encryption key.

I also update as the pins I am using are different from the one slipx06 uses.

uart:

  rx_pin: GPIO16
  baud_rate: 9600
  stop_bits: 1
 
modbus:

  flow_control_pin: GPIO4

I also update the fall back SSID \ Password and the OTA password. I then Save and Install the settings and all appears to run through. I start to receive logs but entity values never appear in Home Assistant and they are marked as Unknown.

I have download the log  Log.txt

and noticed there are lots of these

[11:07:11][W][modbus_controller:113]: Duplicate modbus command found: type=0x3 address=81 count=1
[11:07:11][W][modbus_controller:113]: Duplicate modbus command found: type=0x3 address=84 count=3

and these

 

[11:07:07][D][modbus_controller:032]: Modbus command to device=1 register=0xBE countdown=0 no response received - removed from send queue
[11:07:09][D][modbus_controller:032]: Modbus command to device=1 register=0xF3 countdown=0 no response received - removed from send queue

Is this normal?

I've also noticed when I push the code down it displays a warning about using Pin 4 for flow control, again is this normal?

pls send me your yaml you pushed onto the esp32,

are you running 5.5 or 8.5 kw inverter

looking for code for 5.5

Hi George,

Are you running a sunsynk 5.5 inverter and trying to get the ESP32Dev board and TTL>RS485 board working?
I am almost there but I am seeing in the logs

mind pointing me to slipx's code... can't recall if his was for a 5.5Kw or 8.5KW inverter.

atm my HA running ESPHome on a little Pi3 is crashing when trying to compile/link/install the bits onto the ESP32.

what you running your HA on? wish my friend have upgraded his Pi3=>Pi4 by now...
