Solis S3-WIFI-ST (Gen 3) Data Logging Stick #63

Open OneScuzzie2k opened 2 years ago

OneScuzzie2k commented 2 years ago

Dont seem to be able to use this stick? as its a a 14 digit serial number with letters and numbers, any suggestions?

Ghostofapacket commented 2 years ago

Resolving this to "work" is a case of changing the end of line 30 on "config_flow.py" from )): int, to )): str,

However I am currently in the same boat and having done this, I am now testing to see if this can even poll the inverter correctly.

OneScuzzie2k commented 2 years ago

This allows me to enter the serial but does not talk to it still

Ghostofapacket commented 2 years ago

Agreed, I did some more work on this and it is due to the hex encoding where it is expecting an int but we're now passing it a string.

I need to spend some time to see how the developer has been doing this request and even if this request is possible on the newer model of loggers.

I have one here, I will do some looking over the coming days and report back

Thank you for your work on this. There are quite a few people at HA Community in the same boat!

Thank you also for your great work on this. I really hope a way forward can be found with this issue as it seems all new installations are having this new logger.

I have a week old installation in the UK and have the new stick. I cant even get in with admin:admin even though it obviously has a web page and I can ping it.

The username is admin and the password is your wifi password - however, port 8899 is not open on the S3-WIFI-ST stick so none of these Solarman integration libraries will work. I've not yet found anyone that's managed to read / write directly to the modbus port via this stick so it may not be possible. I also have not yet been able to find a source for the solarman based data loggers that DO expose modbus.

Ended up replacing the stick with a Pi Zero and modbus adapter, reading values perfectly now, just need to work out how to write them

blongden commented 2 years ago

@NickSutton Looking at doing exactly the same thing so I can talk to the modbus interface over wifi. How did you hook up the modbus adapter to the pi? Can you power the pi from the +5V pin on modbus?

I used this https://github.com/incub77/solis2mqtt with this adapter https://www.amazon.co.uk/gp/product/B016IG6X7I/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1, soldered it all together and it even fits in the original SOLIS Wifi stick case. Powered by the 5V pin from the solis

Any success with being able to write?

NickSutton commented 2 years ago

Nope. I was thinking to find a Python guy on Fiverr or something to see if a freelancer can make it happen

jonathanfurness commented 1 year ago

Wondering if there is any update on this thread? I self-installed the Solis Hybrid 5G inverter with a Solis Datalogger WiFi stick (v3) and as others have described, won't work with Solarman.

Nick, as a Pi person, would love to find out more. Have you documented this any where?

dezfutak commented 1 year ago

I found a Gist which enables direct communication via an RS485 to USB converter connected to the COM output on the Solis (so no Solis dongle) & have it all working - just been too busy to document & tidy up all the code properly, but the work in progress is here:

Would swapping the S3-WIFI-ST stick with a Solis DLS-WIFI work for a RHI-4.6K-48ES-5G inverter?

If the same as S4-*, then you can try port 502

Should work, works for me with Solis RHI-3P10K-HVES-5G, check the SN mentioned in readme
