ESPHome modbus Growatt ShineWiFi-S

RT1080 · July 3, 2023, 7:43pm

Hi everyone, with energy prices turning extremely negative (we hit ca 40c negative including taxes for multiple hours last Sunday) I would like to explore the following use case:

disable PV
charge battery from grid

Right now I flip the PV switch manually and instruct the battery via modbus to charge at x% for x hours. Obviously as this is expected to occur more often I would prefer a software solution. Anyone know if this is possible on growatt sph? I could not find anything in the modbus commands.

I am able to set an export limit but that only results in a net export cap to grid as opposed to a cap on PV production.

Any tips would be much appreciated (and I suppose that many people on dynamic contracts are looking for the same)

I solved my Problem to control the Output Power via Mqtt.
I used this

- platform: mqtt_subscribe
      name: "mqtttest"
      id: mqtttest
      topic: the/topic 
      on_value:
        then:
          - lambda: |-
              esphome::modbus_controller::ModbusController *controller = id(growatt);
              uint16_t reg = 3; // Register: Max output active power (in %)
              float value = id(mqtttest).state;
              uint16_t register_value = static_cast<uint16_t>(value);
              modbus_controller::ModbusCommandItem setOutputPower_command = modbus_controller::ModbusCommandItem::create_write_single_command(controller, reg, register_value);
              controller->queue_command(setOutputPower_command);

One thing I noticed is that only the kWh are recorded in 0.1 steps. Is it possible to change the resolution?

Just go to my repo, i created a new version, u can setup the update speed, etc.
been running for weeks now

Today I added my second inverter to my ESphome. Working fine.

I was wondering how you guys handle the unavailable state in HA when the inverter is offline. Any tweaks for this, or just accept it?

RT1080 · July 29, 2023, 6:51pm

Did anyone implement export control on the esp modbus setup?

Would like to implement a switch (on / off) - that part is easy. Not sure though how to interpret “Export limit power rate” which suggests -1000 ~ +1000 in steps of 0.1% - how would this range work? Especially the negative part. Any tips more than welcome!

I own a MIN3600TL-X.
You must wire to pin 3 and 4 on the SYS COM port for the 485 MODBUS interface. 3 is A, 4 is B as per the picture you added.
Then in the ESPHOME script you must specifiy the TX/RX pins on your ESP board to which the TTL board connects. And these pins depend on which ESP board you use.

In my script:

esp32:
  board: mhetesp32minikit
  framework:
    type: arduino

...

uart:
  id: mod_bus
  tx_pin: 23 
  rx_pin: 19 
  baud_rate: 9600
  parity: none
  stop_bits: 1

Hope this helps

I made mine like this

- platform: modbus_controller
    name: "Export Limit Power Rate"
    address: 123
    value_type: U_WORD
    min_value: 0
    max_value: 1000
    step: 50

Can you show me all your code for this can`t seem to get this work with a button to push to set.

More exact how did you make it stick?

Hi candidotsa. Have you fixed it? I have the same problem with: Got Modbus frame from unknown address 0x02!

candidotsa · August 17, 2023, 10:55pm

Hi. Not yet. Just finished to change the D1 to a esp32 and the problem is the same. Do you have any issue (error) in the inverter? I think that this started when the inverter start showing the error in the temperature later in the ac but always working fine. Recently they send me some files to update and now I have no erros. The fault problem is fine but the Modbus no.

candidotsa · August 18, 2023, 12:02am

I changed the address to 0x02 and I get the value 128 to all of the readings.

nikiyahoo · August 18, 2023, 1:39pm

I also tested addresses 0x02 and 0x03 and yes, most of readings are 128. I do not have any errors in inverter. I think it is error of decoding data from invertor. ESP receive two addresses but device is one. I am not familiar with Modbus. Someone to help?

lamare · August 24, 2023, 6:16pm

Have been thinking about this and it seems to me one needs a stick with original firmware in order to keep the app working, so one would need a solution with a “man in the middle”.

I see two possibilities for how to do that:

Remove the serial to usb converter on the stick with original firmware and connect the serial leads to a uart on a second esp board or stick.
plug the original stick into a board with support for serial over usb, such as a RPI and connect that board to the inverter using RS-485 by either plugging a usb-to-485 converter in the inverter’s usb port or use the shinebus connection on the syscom port. The latter is a problem in my case, since that’s already connected to a current meter for measuring the current to/from the grid. So, I was thinking about using the RPI I have HA running on and use a usb-to-485 converter on that side as well, so I can connect the RPI over 485 to the usb connector of the inverter, which should work with https://github.com/WouterTuinstra/Homeassistant-Growatt-Local-Modbus without needing an esp.

For both options the board in between the inverter and the stock stick needs to relay modbus frames from the stock stick to the inverter as well as the responses from the inverter back to the stick, meanwhile communicating with the inverter for it’s own purposes when the stock stick is quiet.Thus it needs to present itself to the inverter as a modbus master and to the stock stick as a modbus slave.

candidotsa · August 25, 2023, 6:32pm

Hi. Thanks for your response, since the beginning that I’m using a TTL adapter.

Nickthegr8 · August 29, 2023, 5:18pm

same here everything just stopped after HA and esphome update to v20230802 with similar error,

if anyone finds a solution please let us know, thks

BigJ0 · August 31, 2023, 7:33am

Hi all,
I can confirm that this configuration is working. I have the same setup with SPH10k, Wifi Stick for growatt cloud, esphome device on port RS485-3 (pin 1 & 5) with a cycle of 15s for local storage. Works like charm. Thanks for sharing.
But one question remains: which version of the growatt RS484 documentation is the base for your sensor configurations? I compared with version 1.2.4 and 1.2.0 and both only fit partially.
Thanks again

Nickthegr8 · September 1, 2023, 11:06am

@candidotsa @nikiyahoo did anyone find a solution? I have same setup as u candidotsa, i even was able to revert to a previous ha backup but still it isn’t working, give duplicate modbus …

candidotsa · September 1, 2023, 9:03pm

i’m working on that but i’m stuck can you post your logs?
