Do you still have 2 Solaredge devices? I see there is a conflict with something else. Remove both - restart app - add 1 inverter ---

I will look into that app. I had wanted to have it in one app so not have to switch for the info, but if it isn’t in de modbus data (I guess) then it won’t be possible I guess. ---

Hi Pieter. Sorry for my late reply. I have a new internet provider so I had to reconfigure my complete network. But it worked! Thanks! ---

I will upload an updated version to test soon which has the following new features: - StorEdge: ability to use Homey as Remote Control. You can choose when to (dis)charge your battery and can even change the charge and discharge power parameters. If you combine this with my other app (Solcast), you can charge your battery during off-peak hours, when no sun is forecasted. Or you can use it to charge according dynamic energy prices. More documentation in the first post + [https://www.photovoltaikforum.com/core/attachment/88445-power-control-open-protocol-for-solaredge-inverters-pdf/](https://www.photovoltaikforum.com/core/attachment/88445-power-control-open-protocol-for-solaredge-inverters-pdf/) These are advanced settings and at your own risk. (depreciation of battery, unplanned charging or discharging) **Nice to know:** This Solaredge app is currently one of the first to support these functions. Not even the official SolarEdge app or website support these advanced configurations. (nor other domotica stuff) ---

Hi, I want to use the values of the app for a Dashboard, MQTT based. For as I can see the MQTT topics are not created by the app. I use the MQTT Hub app at the Homey and MQTT Explorer. These topics are made - homey/solarpanel/[location]/[name device]/$name - homey/solarpanel/[location]/[name device]/$type And these topics are missing: **Solaredge - Solar Power** homey/solarpanel/[location]/[name device]/measure-power **Solaredge - Heatsink temperatuur** homey/solarpanel/[location]/[name device]/measure-temperature **Solaredge - DC Voltage** homey/solarpanel/[location]/[name device]/measure-voltagedc **Solaredge - Totale opbrengst** homey/solarpanel/[location]/[name device]/meter-power **Solaredge - Status** homey/solarpanel/[location]/[name device]/status May be it is a feature request. Any help would be appreciated. Kind regards, Bert ---

Honestly I have no idea how to do this, but I think this something for the MQTT hub and not for the solaredge app. The Solaredge uses some custom capabilities, maybe that is why. I tried mqtt hub a couple of months ago and I could receive all the data in Home Assistant from Solaredge ---

Integration with my SE5K inverter is working great, much better than API integration. Thanks for that 🙂 I have only one question, is it possible to view AC voltage and generated current without the Energie meter? ![IMG_1938.PNG](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/6/9668d983cc972f7d31edf7fb6ea8fb78da706b1b.jpeg) ![IMG_1939.PNG](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/2/f233b0a1df9cbd0dc33d99d5d214ff7beadeb7fa.jpeg) Thanks! ---

I have to look into that. According the manual it is possible, I will make a test version in the next week. What you mean with current? Have a look at this file, and tell me the parameter you want: [https://www.solaredge.com/sites/default/files/sunspec-implementation-technical-note.pdf](https://www.solaredge.com/sites/default/files/sunspec-implementation-technical-note.pdf) ---

Ah you have 3 phase? Sorry then it will be for the ‘ future’ Currently the app is for 1-phase, as I need to rewrite the app for 3-phase. So sorry, when I have some (or better a lot) of time, I will rewrite the app. ---

Hi No this info is not in the modbus data. You can check in the modbus documentation which info is available. I know there are some unofficial ‘tools’ to get the data, but this requires you to ‘catch’ the data send to the Solaredge servers. That’s not the purpose of the app. ---

Ruben, if you have node-red you could read the values yourself. This video [Obtén los datos de tu Inversor Solar](https://www.youtube.com/watch?v=HaTI7-ui0_Y) shows how to read your inverter using node-red-contrib-modbustcp. You can figure out and read the values you want. It’s in spanish though. the nodes required to read an process the values ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/2/d238b93c997e05248c9758f824a2c8c94b10c6b3.png) this is an example how to read the buffer values ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/0/20b6f6ae75822887fbbc5e3e0f0df591dad0a535.png) ---
