Starting a new thread as this was getting lost in the Hints, Tips & Troubleshooting thread.
Post details of your integration with Home Assistant etc.
Bit4 corresponds to Battery Reserve mode.
I suppose the question is, do I set 43110 to 33 when I want to charge from the grid and then set it back to 49 when I want to stop charging from grid?
Yea, I also found Forcast.Solar to be quite inaccurate... And when looking at it as a graph in the Energy Dashboard in HA, it can hide how in-accurate it actually is: It updates its forecast all through the current day, so what you see at the end of the day is the result of a series of updates all through that day. But... this is of no use if you're deciding to charge... you need a forecast that is accurate at e.g. 2am, and the value it gives you at 2am is often very different (and more inaccurate) to what it'll tell you at the end of that same day (what it shows you in HA)...
Here is my actual generation vs Forecast.solar (taken at 1:45AM every day) for the last couple of months. (I don't use Forecast.solar for charging)
And here is a home-rolled forecast based on met.ie data (I use this for charging)
Yes fine the same with forecast.solar being way off. I find solcast to be pretty bang on for me but now broken with latest home assistant. Be interested in the other forecast details for winter time as that is showing incredible accuracy
Thanks will give this one a go.
Is solcast working for you on latest home assistant? Since updating mine is way off and shows forecasts if 2000+kWh a day!
Can I ask how you got the graphs from Solcast on HA? as when I choose Statistics Graph, there is no entries for it?
Probably: Set each mode you want on the inverter and read the register. Then "replay" that via your automation whenever you want to set that mode.
(I only say probably as its difficult to give absolute advise remotely here...)
Does anyone know how I can get over this please??
Fixed in git. Until the next stable release, overwrite config/custom_components/solarman/inverter_definitions/solis_hybrid.yaml with this:
config/custom_components/solarman/inverter_definitions/solis_hybrid.yaml
https://github.com/StephanJoubert/home_assistant_solarman/blob/main/custom_components/solarman/inverter_definitions/solis_hybrid.yaml
The 33/35 values are different for you because you have battery reserve (Bit4) enabled. Your "33/35" is therefore 49/51. Check out the programmer mode on Windows Calculator and it will make sense.
Can I pick someones brains, I want to automate how much my battery is charged by depending on predicted amount the next day using solcast. I have a 6KW System, 10.2 KW Battery, I use between 800w-1.1kw hourly every hour. At present I am by scripts I am manually choosing how many percent to put in my battery between 4-7 (when its cheaper) how is it best to work out automatically how much to put in from the next day predictions? hope that makes sense.
Someone else had submitted a PR to fix the state_class on the battery (dis)charge sensors, but there is a typo in it. I'll submit a PR to fix it later.
In meantime, change line 505 as per below.

Yes all sorted thanks
I don't use Solcast with HA. I use their API to get data, parse it and do my own calculations and then just push it to tsdb and mqtt. I only calculate the total expected value for the day.
I had it here https://www.boards.ie/discussion/comment/119035238/#Comment_119035238. The logic is simple
Daily average(kWh) - remaining battery(kWh) + solar forecast(kWh)
if result is negative then charge the battery to bring it above 0
Will give that a shot later once the battery is not 100%
Thanks
According to the Solis Facebook group, it's possible to setup the new S3 WiFi stick with homeassistant. I'm going to plug away on it and see if I can get it to work.
First up is local access. I wasn't able to connect to the stick, username/pass combo for the solarman doesn't work. I stumbled across the login details for the S3 on a search for something else related to it.
SSID password for it's WiFi network is 123456789. Login to portal 10.10.100.254 for local access. Username is admin and password is 123456789. Super safe, but you can change the password if you want 😅
It seems that it's pulling data from the inverter every 10 seconds but uploads are only every 5 mins.
Have a look through this thread https://www.boards.ie/discussion/2058231583/forecasting-tomorrows-sunshine-to-better-use-the-solar#latest
There are some good discussions in it; it has all the details of what a few people are doing, and links to code. There is quite a lot in it, and it wasn't written with portability in mind. I haven't tried Solcast, it does sound pretty good though.
has anyone connected an elfin ewXX (https://www.aliexpress.com/item/1005002940538337.html?spm=a2g0o.order_detail.0.0.723cf19cTK9kV6) (or similar) via its rj45 to a solis hybrid 5g inverter com port?
the com port, as i understand it (thanks to @reklamos!), is a round 4 pin connector providing GND,VCC,A- and B+
im wondering what cable i need to get for this & from where. thanks!
think that elfin link was dodgy, try https://www.aliexpress.com/item/1005002940538337.html
You could open up the wifi/lan logger stick from Solis and unplug the mainboard from it then you have your 4 pins available
bear in mind im n00b squared here and that sounds like it needs some knowhow :)
i dont have a wifi solis stick. post opening it how would i then connect this to the elfin?
It looks something like this after you open it up (left part) and just connect to the pins using some dupont cables or something similar
I had this done before we had direct solution but in my case I soldered directly to the board as I used both wifi stick and direct modbus access.
does the current wifi stick from solis (https://www.zerohomebills.com/product/solis-data-logging-wifi-stick/) allow access to api/ha ?
If it's the old one yes (depending on firmware perhaps), if it's the new one no.
One of the boards member was unlucky to get a new one, I think these have some buttons on the case whereas the old ones do not.
thanks, afaics the s3 is the new version?
@silver_sky were you able to get the new version of the solis wifi stick working with HA / api ? just looking at your post above seems to say yes??
Can someone point me to the User Manual for the various control modes
I had the new one, and it doesnt work, so I purchased a Gen2 from another supplier, now all working
