HI Guys

I watched Solar Integrations ( Youtube video ) and not getting the Data from my Sunsynk 8K inverter. I am able to connect to the ESP32, I have checked the cables, tried the alternative pins however the Data is not coming through ?

Anyone else had the same problem etc  Any suggestions are welcome,

Thanks 

Hi @Vaughanza

Post the logs from the ESP32 on ESPHome, makes it much easier to try figure out where the problem lies. 

Hi guys

I also watched Solar Integrations Youtube videos, thank you very much, very helpful and informative.

I'm also having issues trying to get my ESP32 and ESPHome to read data from my 5kW Deye inverter.  I've gone through everything 2 or 3 times and can't figure out what the issue is.

My device is set to Master and Modbus is 01

 

Connected my cables to D4, D16 and D17 which is GPIO4, GPIO15 and GPIO16 according to the diagram

 

 

That then connects to the RS485 board as follows, also removed resistor R7.  DI -> D17,  RO -> D16 and RE -> D4

 

My ethernet cable : 

 

I get the following from my logs : 

logs.txt

 

And my config yaml file is : 

Deye.yaml

Your YAML code says 

uart:
    id: mod_bus
    tx_pin: GPIO15
    rx_pin: GPIO16
    baud_rate: 9600
    stop_bits: 1
   
  modbus:
    id: sunsynk_modbus
    flow_control_pin: GPIO4

 

But from your photos is looks like you are connected to GPIO16 & 17, try changing your code to the connections you are using and see if that helps

 

Thank you @Sc00bs, I clearly missed that, was going on the diagram in your Youtube video  🤦‍♂️

 

BUT, I'm still not getting any readings at all.

 

Just to confirm, are my connections correct :  DI -> D17 (TX),  RO -> D16 (RX) and RE -> D4

 

I've attached my latest yaml and log files.

Deye.yamllogs.txt

 

That's not a log, looks like one of your cards.

Check in the log file, it should look like the attached log.

Check your power for the ESP32 board is connected correctly. 

Check the cable from the RS485 to the inverter is connected correctly, try swop it around if still not working. 

Check your TX and RX cables are correct, try swopping them around.

 

logs_inverter_logs.txt

Apologies @Sc00bs, I just copied and pasted but it didn't copy from the logs.  See correct logs attached.

Power is connected 100%

Checked the cable to inverter is correct, orange/white on the left and orange on the right.  Tried swopping around aswell, no difference.

Also checked the TX and RX are correct, had them connected as follows : DI -> D17 (TX),  RO -> D16 (RX) and RE -> D4  then swapped the TX and RX around, still nothing.

 

I'm starting to wonder if the RS485 board is faulty....

logs.txt

Try use 

7 (Brown/White) to A

8 (Brown) to B

Unfortunately did that, no difference. 😞

De and Re do not look soldered together on the RS485 board ?

They were, but didn't work so unsoldered them again to see if it worked. Should they be soldered together?

Where about are you WesleyR? 

I am in Kyalami area in Joburg, you are welcome to bring it through to me and we can work through it together if you like.

 

@Sc00bs, I'm in Honeydew but working in Woodmead, so just down the road from you.  Thank you so much, would really appreciate that.

 

Will PM you my details.

I see you will be sorted. No more worries here😃

Why do you guys use ESPhome when you can get all the data you need using Solarman integration that works using the wifi Dongle, you will have an update every minute and 55 entities with all the info you need.

Because with the ESP device it is basically realtime information, not 1min delayed.  

 

But the most important benefit is that you can change settings on your inverter via the ESP device.  So for example you could set the inverter to charge the batteries before load shedding depending on the schedule which can change at any time. This would be all automatic.

It's a good point and I just watch a Solar Integrations comparing 3 ways.

I use mobile app and local mode to configure inverter thru wifi without cloud.

I automate charge and discharge in the BMS of each battery

We have many options in my case I use the KISS method and avoid put extra hardware when I can fill my needs with what I have. 

So you saying you can automate the charging of your battery based on solar forecast or loadshedding automatically, without you having to do anything?

I don't need that automation but if need it I can do it, I have JK BMS and with Batmon I can turn off charge and discharge of each battery to automate it. 

I have been equalizing my bateries and have using this a lot.

I get this with rs485. I do know the comms connection works as it’s fine with another Linux server.
