Starting a new thread as this was getting lost in the Hints, Tips & Troubleshooting thread.
Post details of your integration with Home Assistant etc.
Is there any harm to be done querying an input register as a holding register and vice-versa? I received a modbus document from KStar only it lists all registers without stating if they are input or holding.
It just won't work, will return an error.
That's good in that I can determine which is which. Thanks.
Can someone help with this oddity? I want to write some code that updates the time on my inverter because it never keeps time and doesn't update on DST switch.
My KStar inverter uses the following registers for date and time...
I adapted some code to output what is currently at those registers...
and the output is...
The date and time are correct on the inverter. Other than month and minute, everything else makes no sense at all.
The responses are BCD. Convert them to hex and they'll make sense (use the hex() function). Except for the year register, that still makes no sense. 🤔
hex()
Thank you. Looks like another email heading to KStar. I am beginning to feel like their guinea pig.
No need. Installed with the wrong date. I have updated it. All good.
Anyone know what type of logger this is, and how maybe to reset it - or what the default logons might be. It's connecting to my SSID fine, and gets a DHCP address, but when I browse to the address, it prompts for creds.
As like allof the other loggers, it's also working in AP mode and so I can connect that way, and when connected, you can get to it by browsing to http://10.10.100.154, but again, when hitting this page, it prompts for creds.
I've tried admin / admin and other normal ones, but no joy
Loving the nest hub, so much better than the esp stuff and easily controllable 😁
Looks like a Solarman LSW-3. Easy way to confirm is whether tcp/8899 is open or not.
Does it work if you turn off Nabu Casa Remote Control? I have Nabu Casa but don't use it for remote access, only TTS and Google Assistant integration.
Not if I turn it off no.
But apparently if your HA instance is on https (mine isn't since I have nabu and never bothered with it) it should also work then but I can't test it.
Port 8899 is indeed open when I telnet to it
Finally a reason for me to get nabu casa, have the smaller nest hub in the kitchen, any guides or does it just work?
This seems to indicate there is a reset button.
Just found that same link myself - thanks
Yes, as Jonathan says, it's a LSW-3 (Type 1) with a D-connector. My KStar uses the Type 2 with a circular connector. They come with the same installation guide. Next to the antenna you might see a button; give it a 10 second press to reset the logger, which might clear the new password. Otherwise, there's nothing you can do further than that.
Just works, you add the Cast integration and you're set.
Here is a handy guide. I just tried it and it works perfectly.
Does anyone have their logger working on the 2.4GHz band whilst also running the 5GHz band. I had fibre installed today and to make the most of it I enabled 5GHz (with a different SSID) and the logger immediately stopped working. I had to turn the 5GHz band off. Also, my smart plugs have stopped working and no amount of pairing them again is working, even though 5GHz is off.
Is the SSID the same? Did you change your wifi point?
Since the clocks change my energy dashboard in homeassistant is 1 hour behind everything else. Anyone know how I can sort this? The actual time in HA is correct.
I've the logger connected to a 2.4ghz wifi repeater due to distance, but have the 2.4/5 issue with other devices. My router allows for the bands to be split so they're broadcast as separate SSIDs. Check if you can do that.
I have noticed that the loggers appear to lock onto the MAC address of your WiFi. I was actually going to ask here if someone knew about an updated firmware which just tracks the SSID.
What I had to do was to setup an SSID on my phone (hotspot) with a different name, save it, go back in again and select the SSID I wanted, and it then changed it ove
You'll see that the table of WiFi SSID's has the SSID, the channel and the MAC address.
So you can't really therefore have two AP's within range, because it could start flipping over to the wrong one, but not connect correctly
SSID is different between the two bands. What is meant by "wifi point"?
And I have the same SSID for both 2.4ghz and 5ghz
And make sure your 2.4ghz uses only ch 1, 6 or 11, and has modes b and g enabled. A lot of these type of devices know nothing about n (802.11n)
All modes in operation. No choice of channels.
I'll keep 5GHz off for now. I may put devices that need a high speed connection on a LAN or put 5GHz on, read the inverter off the COM port and get compatible smart switches.
Lots of projects. Nice to be back into computing in retirement so long as it doesn't interfere with the vegetable garden or the DIY synth.
This may be interesting. Having issues with my zappi with vhub dropping server connection which is breaking my homeassistant energy dashboard. Local data would be great.

myenergi API data is in UTC with no DST adjustment in the integration 😖
Added some usb powered pc fans over my invertor to draw away heat. They switch on based on the internal temp of the inverter. Using home assistant and givetcp (givenergy) using a givenergy smart plug. Seems to work pretty well. Last nights inverter temp plot.. peaks at 35c, fans kick in and they drop down to around 30 pretty quick.. fans switch off after about an hour.. been running last few nights and see the same behaviour
HA now running with KStar inverter via Solarman integration.
For KStar owners who want to use Home Assistant, the set up is on Stephan Joubert's GitHub page at https://github.com/StephanJoubert/home_assistant_solarman
The yaml configuration file for KStar can be found at https://github.com/StephanJoubert/home_assistant_solarman/pull/253/commits/95ac7f74bedb6f0f9a5c5374cc0d66e12cc29d39
Make sure to name this inverter definition file as custom_parameters.yaml and select that when configuring the Solarman integration.
You might also consider updating your inverter firmware to the latest iteration by contacting KStar at service_solarinverter@kstar.com with your Solarman logger serial number. The battery was not recognised on my system until after the firmware update.
With MyEnergi now selling rebadged KStar inverters, this inverter will become more common. However, MyEnergi uses their proprietary Libbi device connected to the COM port rather than a Solarman logger so a MyEnergi integration will be required for Home Assistant to see the MyEnergi version of this inverter.
I now have my Smart Life (Tuya) sockets and eWeLink temp/humidity sensors integrated with Home Assistant and am now starting on immersion heater integration. Hopefully, that will be followed by an Air to Air heat pump and its integration.
Thanks to all in this thread (and Stephan's) who assisted me. Many hands make light work.
