Interesting read @Satal! At this moment there's no indication in the API v1.2 that they allow sending instructions to the inverter. |

They didn't provide any further documentation than just the screen shots. I'll ask them if there is anyway to access this through an API and let you know what they say |

@hultenvp, after quite a lot of back and forth with the Solis support team, they've said that there isn't an API for Remote Control. I've had a quick look at what happens in Chrome when you save, and it appears that a call to {
"cid":"103",
"inverterId":"[My Inverter ID]",
"value":"50,50,00:00,00:00,00:00,00:00,0,0,00:00,00:00,00:00,00:00,0,0,00:00,00:00,00:00,00:00",
"localTimeZone":0,
"language":"2"
}The value above appears to be comma separated values for the "Charge and Discharge" settings
The response to the request is: {
"success":true,
"code":"0",
"msg":"success",
"data":[
{
"msg":"Home Inverter : [My Inverter ID] Time: 1673868200<br>NO: 176<br>SN: [Inverter Serial Number]<br>Result: 0<br>Inverter1: <br>send: <br>recv: [Receiver number?]<br>",
"code":0,
"recv":"[Receiver number?]",
"command":"AT+TEST=GIN[3 digits]:01 10 [HEX] [HEX] 00 1e 3c 01 f4 01 f4 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 f1 79"
}
]
}That may all mean something to someone with more experience than me. |

Looks a lot like the old Ginlong V2 API, which uses kind of the same request-response pattern for reading data. Shouldn't be too difficult to write some code for this, but I do not have the right logger for this myself (same as @alienatedsec ) |

What is your datalogger @Satal ? Mine is DLS-W running |

Both platforms - HA (solis-sensor) integration, and web interface - use the same API - one difference, the reporting API and controlling API have different permissions. Also, the former is published and the latter seems to be isolated with explicit access to Solis solutions only (e.g., remote web interface). I guess, the API was initially created for data to be managed outside of the Solis Cloud, and for your own benefit. |

Hey - I've just ordered those parts! I might be looking for some help in a week or so! |

@sjoram happy to help. Please remember to post any questions in the repo rather than over here. |

Does your solution allow for writing back to the inverter to control it via HA to for example automate import from grid to charge batteries at the cheapest 30 min period? |

@magichew it does allow when combined with the right integration and the ha automation around it. Lots of work, but there are many guides and videos on how to approach it. |

Just a note that Solis support today told me that remote control only works on hybrid inverters, not string ones (like ours). |

@haydnw they forgot to mention that only certain dataloggers are supported when it comes to the remote control. |

Did anyone ever get this working? When I try to send data to that endpoint, I get the following: { If anyone ever got a python script to work with this atCommandV3 endpoint, please share.... This is killing me :) I'm starting to wonder if this endpoint allows "API" authentication. That "Resource" (resource1300386381676591899) I have no idea what that is... Its not in my headers or body, Its not the inverter ID. etc.. Wondering if theres a way to "scrape" and pretend the script is a web user and not api.... |

Hello, I noticed that since a few days there is also support for string inverters. At least my model gives an On and Off button to control my Solis inverter remotely! 🎉 So I reached out to the local support team immediately (Netherlands/Belgium) because a few days earlier they enabled the remote control for me. Got a blank page and after some messaging we came to the conclusion that mine was a string converter which isn't supported. So I asked if it was planned in future and he replied with no. He told me later that he also reached out to China (headquarters?) Apparently there is new software released inbetween those days which makes this feature available. I looked for release notes or whatsoever but couldn't find anything. |

I wonder if we can create a HA service for this, especially now HA services also can return data. |

Hello All I too have been interested in remote control of the inverter. I reached out to Solis UK earlier in the week, by creating a support ticket (https://solis-service.solisinverters.com/en/support/tickets/new), requesting any documentation for the remote control API. SolisCloud Platform API Document - Device Control V2.0 Sections 1 and 2 of 'my' document appear to be the same as sections 1 and 2 of the document (SolisCloud Platform API Document V2.0) stored in the repository, leaving only about 6 pages of "new" stuff. The document refers out to a s/sheet containing a list of data items it is possible to set/retrieve. This lists things like charge times/currents etc. i.e. the same items that can been seen on the app's Inverter Control section. Maybe if more of us reach out in a similar way, maybe they can be pursuaded to release the document without the NDA? Meanwhile I am going to reachout to them again requesting permission under the NDA to share the document with the dev-team, for the purposes of updating the plugin and distributing. |

This is very interesting. I am currently getting quotes from an installer for a system including a Solis Hybrid inverter. If there is API access to control battery charging I will push ahead with the install and if possible help out any work here to integrate. I am looking to control the battery charging using a solar prediction for the following day to determine how much of the battery to charge on cheap rate overnight power and how much to leave for solar the following day. Has anyone else done this for other systems? |

@FrankTaylorLieder there are plenty of ways to manage your battery but the API is not the best to handle it. Please check the following: https://github.com/fboundy/ha_solis_overview << connectivities explained |

As a software engineer doing it entirely in software intreagues me. Just in the same way as I haven't spent money on a zappi, but have developed with the help of somewhere else on the interwebs cant remeber where though, a Home-assistant integration to charge the car on the excess - after the battery and hot water are fully topped up. To date though I haven't managed to even login (must dedicate more effort to this project). I have seen solutions like the bottom link which requires extra hardware to implement, however I am not yet prepared to go to that yet. However it would give more realtime information. While I like the inverter and battery setup, one feels that the 3S-Wifi-ST has been produced too cheaply and takes out of our hands things which might have been useful. SolisCloud needs the ability to get the data more frequently. The API shouldn't be behind a NDA. Then again SolisCloud and all your data goes via China, and what if SolisCloud goes down. |

@bryanajwells hence, why I made what I made and feel completely independent - I was away in December; however, noticed in January that my Datalogger is down and not reporting to SolisCloud - not bothered at all as all my data was, and still is, and will be in Home Assistant. |

For those following this thread - I found this today quite by chance. I was looking for something else. |

Hi, I'm also very interested in this. I'm new to HA and I think it would be really useful to set certain parameters of the inverter. Mainly to decide when to charge the battery from the grid and when to allow discharge of the battery. It looks like the inverter control has recently been rolled out to everyone in soliscloud.com. I wonder if this means that it can now also be changed over the API. I'm not familiar with plugin development, but I'm happy to help in testing some functionality. |

I applied for access to the API but after two weeks I still hadn’t received a response. I responded to the auto generated ticket and then got a response. They wanted me to fill out a non disclosure agreement.
After reading through all the fine print gave it up

Hmmm. Seems strange to have an API and give it out, but not want anyone to share details of it. Of course we can always reverse engineer it :-) Thanks for sharing your experience. |

I put a very rough draft together in https://github.com/nathan-gs/solis-control it handles the forcechargesoc, forcedischargesoc. |

Hey all,
I'm not sure if this is the right place, but I thought I would share it as I imagine it's something that a lot of you will be interested in.
While submitting a ticket to Solis, I noticed that there was a category to request remote control of your inverter. This allows you to control the inverter from the website or your phone. From a brief look it looks like you can control anything that you could directly from the screen on the inverter.
For me, the main use case is being able to set the charge from the grid without having to climb into my loft. I'm guessing that this is exposed via some API though I doubt it's going to be the same API we're using for reading the information.
To get the Remote Control Access, go to the Solis Service Center and submit a new ticket specifying the "Product Type" to be "PV Inverter" and the "Tickets Type" to "Remote Control Access", filling out the rest of the details as you would normally. I would recommend being clear in your description that you want Remote Control Access in addition to the API access, as initially, the support team tried adding API access a second time, despite me already having it enabled.
You should then get a response in a day or so letting you know that the Remote Control Access has been approved and you need to log out and log back in.
In the email, you'll get the following screenshots of how to access the Remote Control area.
You will also be able to access it through the website, which looks like this
Whether you go in through the app or the website, they will present you with a disclaimer that you have to agree to regarding the use of this functionality.
Anyway, I thought I would share and hope it is useful 😊
