ESPHome modbus Growatt ShineWiFi-S

Correct, in my case, the USB is just for power.

The green/white wires are cut and don’t connect into the USB-A connector.
Instead, they connect the RS485 converter to pin 3&4 of the COM port.

Red and black take 5v from the USB-A, over to the D1-mini and the RS485 converter.

This was the RS485 converter I used: Stable UART Serial Port to RS485 Converter Function Module RS485 to TTL Module k | eBay

And this is how its wired:

I had previously tried the ESPHOME ‘growatt_solar’ sensor platform with this hardware.
On my 1500TL-X, it read one or two values. But most were NaN.
However, with the code here, it populates all values perfectly.

Internal: false needs to be added to all exposed sensors as of the last esphome version

45

Thank you for keeping an eye on the topic! In this case it is only about the homeassistant platform. So no worries.

46

Sure? It’s says All sensors. Not in line with the title of the issue

47

Yes im sure. The GitHub pr is a little misleading. I updated my device today and it is al fine😉

48

I found a way to upload to pvoutput.org, from home assistant.
PVOuput Uploader - #26 by rieschard

Next step is to do it in esphome. That shouldnt be too hard

49

Is this code also working on three-phase inverters?

I’m preparing to test it out on a Growatt MOD 5000TL3-X with ShineWifi-X in a few weeks, when the inverter is powered up

Yes. Get the code for de X Growatt/shinewifi-x.yaml at 696aab77c35bceb7e72333253cfb7fa8c6d04c1e · WilbertVerhoeff/Growatt · GitHub if you need help, please let me know.

For everyone that is using my previous code. This is better and far more accurate and reliable.

Grid Power Today can be used for incoming old power if you’re grid connected (input)
AC Output Today is all AC Output from the device.
Charge Power (today) is how much AC charging from the grid.

This lets you put in accurate values into the Energy tab. I’ve tested all of these values against a calibrated meter and they’re within like 1-2% of real. Let me know if there are any other values anyone would find useful. (for other inverters there are data points for multiple PV inputs etc. and this should work for all “off grid” inverters. It won’t work for grid connected.

I’ve modified @pasarn’s code for the ShineWiFi-X to include PV1 and PV2 power.

As it turns out DcPower presents only presents the power of string 1 (PV1). If you have a dual string inverter like me (Growatt MIN 5000TL XE), you can include the following code in the sensor part to get the DcPower of string 2 (PV2) as well.

  - platform: modbus_controller
    name: "${devicename} DcPowerPV2"
    address: 10
    register_type: "read"

    device_class: power
    icon: mdi:flash
    value_type: U_WORD
    accuracy_decimals: 1
    filters:
    - multiply: 0.1

I would also suggest to rename DcPower (from @pasarn’s code) to DcPowerPV1 if you have a dual string inverter.

Hi, I have a Growatt 750TL-X and a spare D1 mini and I’m trying to make the cable from @chopwood so that I can read values off my inverter with ESPHome.

I’ve just noticed my TTL to RS485 converter has different labels on it though? Yours has VCC, TXD, RXD & GND on the left, mine has DI, DE, RE, R0 on the left. Did I buy the wrong thing?

54

Okay after a bit of research I think I connect DE & RE together and also to the GPIO defined as the modbus flow_control_pin. DI goes to RX, RO goes to TX. Cross fingers.

55

Here is my configuration for a 3 phase Growatt inverter MOD 8000TL3-X-AU with 3 string input (even though it only appears as 2 DC inputs)

Pretty straight forward to flash on a Shine-wifi-x, just pop off the cover and connect your programmer to the header inside. Flash with ESPhome and load the code via OTA after that. I bought a second wifi-x module off ebay so I didn’t mess up the registered one for service/repairs.

here is the doc I used to figure out the modbus registers.
http://www.photovoltaicsolar.in/Growatt_Manual/MAX%20Series%20Modbus%20RTU%20Protocol.pdf

Just a note, where there is a high and low in the modbus map - ie the power values, you want to select the address for high (the lower address), and make sure you read as double word value_type: U_DWORD all the others will just be a single word value_type: U_WORD

I checked what values I wanted from the shinephone app, select the datalogger, all parameters, then other data. these values match up to the modbus map perfectly. from here I could see the 3 strings, strangely it was stings 1, 3 and 4

i try to flash my shinewifi-x via esphome. but it is not working. the first question is do you flash it whitin home assistants esphome orw with a different flasher (esptools or somthing). and then you need set de gpio0 to GND on the x self or do you need fom gpio0 to de gnd on the usb to ttl module?

58

AFAIK (just managed to flash my wifi-s) I connected ground and gpio0 and connected the pins to my usb-serial converter. Had to fiddle with rx tx, but then lo and behold, it worked.

And oh, I used the USB port on my home assistant/esphome host. Flashed it through de web server.
Hope that helps?

I use a USB to serial flashing device. They are pretty cheap, and I just used jumper cables to connect to the wifi-x terminals. They are pretty clearly marked. And the gpio0 was connected between the wifi-x and the USB programmer

I did have issues jumping it to the download mode… can’t remember exactly, but I think only 2 of the 3 leds are on… Or maybe all 3 were on in the end… i was in a rush to get it done before school pickup. But I just kept hitting download and power cycling till it worked.

As the new version of ESPhome is out… and its nighttime… i decided its a great time to open up the unit and flash it via USB. this is whats inside

to flash you need to jumper GPIO0 and GND together and then plug in the USB. only 2 LED should be lit. no need for an external programmer

after this just flash via USB from ESPhome as normal.

And dont be an idiot like me and spend 10min trying to get USB logs out of the thing to make sure its working… they are disabled! it worked instantly with wireless logs

Now that I know what’s inside and have a better idea of what’s inside I think any ESP device with USB should work, like a $7.50 d1-mini. Seems a waste to spend $75 to get the pretty unit unless you need the water resistance the cover offers.

perhaps one day someone will work out the RTC and make some pretty status lights. i think it would be wise to set the time in the inverter for error logging.

i have try it but it fails it say Failed to initialize. Try resetting your device or holding the BOOT button while selecting your serial port until it starts preparing the installation. but i have try to upload the firmware to a esp8266, and that works great it runs now for 2 days and its amazing. thanks all for your help.

62

Yeah I did get that message a lot, then I just kept plugging in and out till it worked.

Did you get the 2 led’s or were all 3 lit? Or sometimes all were off

The most consistent way was to bridge gpio0 and gnd then plug in the USB.

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?
