Hi Edwin Thanks for your support so far, it’s very much appreciated. I have installed the SolarEdge TCP App and it is working fine, alongside the other Modbus app I use for my Solax. I guess that must have polling enabled too - which is great. I have taken a quick look at the data and it seems closely aligned - will look in more detail and present any obvious omissions or apparent conflicts that I see. The only **change** I would request at the moment is to add Time of Use (TOU) to the use mode dropdown. When I first installed and looked at this list, the “cursor” was positioned “off the top of the list”. I moved down to a mode and it was correctly selected - but there was no way back to TOU use mode inside the app - I had to use the Solax web interface to reselect TOU. I guess there is a link between choosing TOU and an appropriate value of “Storage forcible charge/discharge”. I will look in GIT to add this request. Thanks again. ---

Hi Edwin Yes, added it and everything is working fine - all the sensors pick up the right data and the controls for _Use Mode_ and _Discharge Mode_ selection are present. Thanks very much for providing such a great app. Right now I continue to use your app alongside the other Modbus app I have been using because I need to convert all my flows. Once that is done your app will become the only one I use. I stress again, there is absolutely no fundamental problem with the integration. However, in the last two years, Solax has added new _Use Modes_ called _Time of Use_ (TOU) and _Peak Shaving_. > **This is what the Use Mode control shows me in Homey: (use the ⯈ to show the image)** > > ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/d/9d40c9adc0f3698309623c461466726fcf6e0e39.jpeg) As you can see _Time of Use_ and _Peak Shaving_ are both absent from the list. This means that if I use the _Use Mode_ control in Homey to select a different Use Mode, the only way to get back to _Time of Use_ is by using the Solax web interface (or the Inverter’s front panel controls). As a note. When I first installed the app and displayed the _Use Mode_ control, the “selection cursor” was not positioned in the list at all. Once I moved it with cursor keys (or mouse), it “entered” the list on Self Use Mode. I guess this was a symptom of the fact that the inverter was in TOU mode, but this is not available as a value to select in the list of available options, so Homey did the best it could in positioning the selection cursor. You commented in a previous post that you had version 3.21 of the Modbus documentation. The TOU feature was first documented in version 3.29 (Peak Shaving in 3.23). I previously shared [version 3.34](https://drive.google.com/file/d/1e_vji43o48sS3BWVQNQUjctl6VMFMhvL/view?usp=sharing) that I obtained direct from Solax - it documents both the new modes. > **Version 3.34 documents SolarChargerUseMode as follows: (use the ⯈ to show the image)** > > _ReadHoldingRegister:_ > > ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/d/6d1b85ca24845b28a283f80a7164aed3c76901dd.png) > > _WriteSingleRegister:_ > > ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/0/b01d179d2e55084af86e76fca7f0e3f949ceaf25.png) > **solarcharger\_use\_mode capability - from your git repository** > > I guess this is the core of the change that will be needed… I am happy to clone the repository make a change and test it if that would be helpful to you. > > [.homeycompose/capabilities/solarcharger\_use\_mode.json](https://github.com/biemond/solaredge.modbus/blob/main/.homeycompose/capabilities/solarcharger_use_mode.json) > > ```json > { > "type": "enum", > "title": { > "en": "Use mode" > }, > "getable": true, > "setable": true, > "uiComponent": "picker", > "uiQuickAction": false, > "values": [ > { > "id": "0", > "title": { > "en": "Self use mode" > } > }, > { > "id": "1", > "title": { > "en": "Feedin Priority" > } > }, > { > "id": "2", > "title": { > "en": "Back up mode" > } > }, > { > "id": "3", > "title": { > "en": "Manual mode" > } > } > ] > } > > ``` I hope this clarifies my previous comments. ---

Does anyone know how to exclude the device from the total house consumption? I have a smart meter on my mains (shelly 3EM) but the total consumption in the app is wrong because the solar power doesn’t neet to count for it (shelly measures the total, and the solar is added to this) ---

hey, don’t understand this , with meters and PV it knows it perfectly and no need for shelly. ---

i don’t have digital meters so the shelly gives the total consumption and the app gives me an idea of how much solar the panels generate but i doesn’t need to add this to shelly 3em because this is rhe true mains power (sometimes negative value if solar produces enough) ---

on advanced properties on the device , you can exclude it from energy. that is it I guess ---

On the huawei It doesn’t have that function, in advanced properties there is only Ip adress, port and inverter id Probabley have to make a virtual device in some way with a negative value off the solar panels to correct this ---

weird should be the default handled by homey. maybe it is a pro 2023 feature. ---

Hi everyone, I’ve been trying for several days to connect my **Huawei SUN2000-4.6KTL-L1** inverter to my \*\*Homey Pro (2023)\*\*using **Modbus TCP** , but although the connection seems fine, I’m not getting _any data values_ in the Homey app or in the Energy tab. I’ve read through the entire Growatt / SolarEdge / Huawei Modbus TCP community thread but still can’t get it working. ### **My setup** - **Inverter:** Huawei SUN2000-4.6KTL-L1, Battery LUNA2000 - **Homey:** Homey Pro (2023) - **Network:** UniFi network, inverter on fixed IP (192.168.40.x) ### **What I’m sure about** 1. **Modbus TCP** is _enabled_ on the inverter. 2. **Protocol type = SunSpec** (confirmed in RS485 settings). 3. **Device ID / Unit ID = 1**. 4. Port **502** is open 5. The Homey app detects the inverter (“connected” appears). 6. However _no data at all_, everything stays 0 or “no data available”. ### **What I’ve already tried** 1. Verified latest firmware via FusionSolar. 2. Tested multiple device IDs (0 / 1). 3. Disabled and re-enabled Modbus TCP several times. 4. Rebooted inverter, dongle and Homey. 5. Checked Inverter app logs, connection OK but “illegal data address” errors. Changed Protocol to Sunspec. 6. RS485 config: **Protocol = SunSpec** , **Com address = 1** , **Baudrate = 9600**. ### **My question** Has anyone managed to get **values** from a **SUN2000-L1** inverter using this Homey app? Does it matter which device I choose when adding in Homey? I tried Huawei S2 Inverters S-Dongle, and Huawei Inverter + Battery, but the results are the same. ![CleanShot 2025-11-01 at 14.49.19@2x](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/5/e593b86961880a47a72ccf90b19a2518a8038450.png) Thanks a lot for any help or pointers! ---

Have very much the same setup, except for the battery (yet). See that you have tried different ID’s but in my case I hade to use id=2 to get data! Have you tried that also? /PO ---
