I'm struggling with receiving data from my Ginlong Solis as well and this seems to be a very straightforwarded approach.RoyT wrote: ↑Thursday 02 April 2020 7:48 After some failed attempts to get data sent to "Server B" on my Ginlong inverter, I've resorted to a very simple PHP script that runs on a Raspberry Pi (same one as Domoticz runs on). It's executed via cron every minute. It takes data from the local status page on the logger, and sends that to a dummy kWh Meter I created in Domoticz. This adds the current power, and today's total.
Thanks @devros for this old example code. I am now able to fetch 5 minute data from shinemonitor.com for my 3 Deye micro inverters and feed into Domoticz!devros wrote: ↑Monday 03 September 2018 21:57
hello, afaik they changed something in url here is my latest dirty working code
without success .....Although slightly ambiguous that TCP is a selection hidden under menu-item Solarman-Customer, and (probably?) not menu-item Transparant Protocol.#Configuring the inverter Log onto your inverter and click on 'Advanced' Now click 'Remote server' Enter a new ip address for 'Server B' (your computer) enter a port number (default 9999) select 'TCP' Click the 'Test' button and a tick should appear. Click 'Save' and and when prompted 'Restart'
That invites to retry .......Code: Select all

So far, it's works very well. Only downside is that Domoticz shows e.g. 9W at night, because that was the last known value before the device shut off. It's easy though to add some code that sends 0 values between sunset and sunrise, as PHP can calculate those times based on geolocation. Right now, I'm not too bothered by it (the totals are still fine, because I've set the device to use "Energy read: from device").
The script uses a built-in PHP function to do an HTTP GET, so there are no dependencies on CURL or any other library besides the default PHP installation.

I used this script for a while now and it worked perfectly until a week or so. It seems that the www.shinemonitor.com/ws part is not working anymore. I have tried to find out how to work with the api but I get stuck on the company-key so no avail there. Would love your insights to see how I can get it working again.sincze wrote: ↑Wednesday 16 August 2017 21:53 So forum member devros and myself have been playing around to see if we could modify the initial shinemonitor script in such a way that it should work for all kinds of inverters that report their data to shinemonitor.
Kudo's to the devros and his wireshark skills.
Pay special attention to the following values:
pn= on your wifi stick or can be found on the shinemonitor portal after signing in the regular way
sn= the serial number of your inverter. Can also be found on the official portal
devcode= this tricky number you have to extract using for example chrome f12 (under network) to see an initial string between your browser and shinemonitor. It seems every brand has its own devcode.
Just run with Python3 as cronjob every 5 minutes or so.
Have fun!!.

Yes I've the same (local read-out), however if you monitor for other people that don't have Domoticz
it will become a different ball game in the near future.
