More Datalogger Register Commands

[rany2]

This is for ShineWifi-S but might apply for the rest.

I was messing around with my datalogger and found some registers that might be of interest. While the inverter registers are well documented, datalogger ones are not. For this reason I decided to put some info here as some kind of "crowd-funded" effort.

Previously mentioned in https://github.com/johanmeijer/grott/issues/123:

• Register 4: reporting interval in minutes
• Register 8: serial number
• Register 17: growatt server IP
• Register 18: growatt server port
• Register 21: firmware version
• Register 31: datalogger time
• Register 56: wifi SSID
• Register 57: wifi pwd
• Register 76: wifi signal strength in dBm
• Register 80: firmware URL set when attempting update from site

Newly found:

• Register 32: only WRITE, when not zero it restarts the datalogger
• Register 35: only WRITE, when zero it clears log (not sure)

Thanks! I will start documenting it in the wiki soon.

curl 'http://localhost:5782/datalogger?command=register&datalogger=[dataloggerserial]&register=16'

Additional

• Register 16: MAC address of Wifi
• Register 19: growatt server sub.domain.tld - can be used instead of ip (register 17) to point to sub.domain.tld hosting the grott server

On my Shinewifi-s I can't read or set any of those registers. I get an error: "Read Param Failure". Sadly I cannot even change the interval.

[johanmeijer]

Do you use the blockcmd parameter?

[smallbitt]

Oh yeah. It was blockcmd parameter set on "true". So does the interval register works only through grottserver or even directly to growatt server?

[johanmeijer]

It also works with grottserver. See also #93.

Be aware using the grottserver the interval can not set to low (I think not <2 minutes).

I have been doing some testing, and now I have some more to add:

Register 5: Modbus range low Register 6: Modbus address Register 9: Hardware version Register 11: FTP details Register 12: DNS ip address Register 20: Device type Register 22: Version Register 25: Subnet mask Register 26: Gateway ip address

There are lots more with values that I am not sure of their purpose yet?

[rany2]

@cyberdiamond These don't apply to SHINEWIFI-S, or at least the values appear uninitalized on my unit.

[cyberdiamond]

I am using a Shinelan box so maybe some are specific to that?

[cyberdiamond]

To be more exact for any one finding this in the future it is a ShineLink (which is a combination of ShineLanBox and ShineRFStick @ 433mhz)

[cyberdiamond]

A couple of possibilities:

Register 28: Offline data number? Register 30: Timezone (looks like its default set to China timezone)?

curl -X GET "http://127.0.0.1:5782/datalogger?datalogger=NAC5Axxxxx&command=register&register=30" {"value": "LLT+8"}
