App integration to Solarassistant.
Testlink SolarAssistant | Homey
This is an initial release. Build by Claude @ my instructions.
To make it work you need:
Feed back is welcome.
App has been sent for certification.
hi, when I want to install SA to my Homey, I instalkl the app and then click install device, I can give my SA ip and password. But it does not work, I get the message cannot connect.
My SA is online, and on my LAN, http://192.168.1.116/ and I have my password for this webportal. What is going wrong here?
Thanks 
edit; Sign in | SolarAssistant is this the password what is needed for this site/portal to login?

@Philippe_Rosier Hi Philippe. You need to set a local password on the configuration page of the SolarAssistant.
Go to configuration page
Click on “Configure local access”
Change/update the password
(username “admin” will remain, you only need to update password)
2PS: Setting the local password will not affect your normal signin/login (email/password).
v1.1.0 – separate Solar, Battery and Grid devices for Homey Energy
Version 1.1.0 is available as a test version and has been sent to Homey for certification, so it will reach everyone after approval.
Test link: SolarAssistant | Homey EDIT: Now certified: SolarAssistant | Homey
Thanks to Adam S. for the suggestions for v1.1.0. With the new devices, Homey Energy can show your grid, solar panels and home battery.
What’s new
The app now contains
Good to know
Inverter-specific values
SolarAssistant provides “total” values that are the same across inverter models, and the app uses those. Individual values (cell voltages, phase currents and so on) differ per model, so I can’t promise to support them all. If you need such values, my other app MQTT Bridge can bring them in through MQTT Hub (enable MQTT in your SolarAssistant configuration first).
If you are missing a value, tell me which inverter you have. A metrics dump helps, but please remove the serial number first. It it makes sense to build it into the app i will try.
What it looks like
I see I have 1.0.14. Will it automatically update to 1.1.0?
And: my SA also reads out my 3x JK BMS data. Can this also get integrated toward/in Homey?
And: in my SA I have also Auxiliary PV power, can this also be forwarded to Homey? + add the option in Homey to have 1 value as total PV power, (so PV power from the strings + Aux PV power combined)
I have a Deye Hybrid, with 2 PV strings, and a microinverter connected on the Auxilary (gen/MI port) 
If you have auto-update enabled, the app will automatically updated. To update manually, you can open the App Store page for the app and click Install
Hi, and thanks for the questions.
1. Version 1.1.0 has been approved, so Homey will update the app automatically. Your current device stays as the “Overview” device, and the new Solar, Battery and Grid devices have to be added through Add device.
2. Regarding JK BMS and auxiliary PV. For now the app is limited to the “total” values SolarAssistant provides as topics, because they are the same for every inverter model.
Values that are specific to an inverter (like aux on the deye) I am probably not going to implement. I am not totally against the idea, but if I get a lot of requests for inverter specific values I could use all my time doing that
In stead I suggest you use my other app, MQTT Bridge | Homey , together with Ronny Winkler’s MQTT Hub:
You can create one or more devices with any specific inverter (SA) value you want. It’s great for thoese “one-off” values, but takes a bit of work to setup.
You can find the topics (values) provided by SA with MQTT explorer on windows. Or you can login to your local SA to show the metrics/topics: http://192.168.1.xxx/api/v1/metrics/
EDIT: Afterthought: I think its possible to add a generic sensor device to my app. It will make it possible for you to choose a specific topic that your SA / inverter delivers. I will look into it, if it works I will publish a testlink later. It will be easier than the MQTT bridge suggestion.
Hi Phillippe.
I’ve published a new testversion of the app (version 1.2.0). In the new testversion you can pick your own value/topic from the SA. It should automatically provide a list of all possible sensorvalues. It means you could pick battery data if SA offer the topic or aux values and add it as a stand alone device to homey.

Just like in version 1.1.0 you have to add a new device, and then chose the new value device. You will then get a long list of values to choose from. You can add several at a time.
The values are included as sensors on the homey dashboard. So they will not/should not show up in homey energy dashboard. You cannot use it to add your aux pv readings as a secondary solarpanel (for that you would need the MQTT bridge/MQTT Hub setup mentioned above).
I will not ask for certification of the test just now. Will wait a little to find out if i like it or not. It means that if you want to try it, you have to install the test version manually from the link (no auto update for now).
Seems like version 1.2.0 works as intended. I have requested the test version to be certified so it will be pushed to everybody with auto update soon. Since 1.2.0 only adds a driver, your current app, flows and devices should not be affected by the update.
Be careful when you change settings. These are real settings in your inverter, and a wrong value can cause problems for your system. Only change settings you understand. The app only sends the value. It does not check that the inverter accepted it, or that the value makes sense for your system (an update to verify the changes is pending).
The app can write settings to your inverter through SolarAssistant, using the Flow action “Send [topic] = [value]”.
In a Flow, add a Then card, choose the SolarAssistant Overview device and pick “Send [topic] = [value]”. Fill in the topic and value, for example:
inverter_1/grid_chargeEnabledEvery setting has a topic name. Open http://<your SolarAssistant IP>/api/v1/metrics/ in a browser and log in with the username admin and your local password. The settings are the entries with "group":"Settings" and could look like this:
{"name":"Grid charge","value":"Enabled","group":"Settings","topic":"inverter_1/grid_charge"}
Copy what is in topic into the flow card. The value shows what the setting is now, so use the same kind of text or number for the new value. Topic names depend on your inverter, so use your own list and not other people’s.
Write the topic in lower case, exactly as shown. Phone keyboards often capitalise the first letter, and a topic such as Inverter_1/grid_charge will not work.
My Deye can charge the battery from the grid, but I only want that when the price is low.
inverter_1/grid_charge = Enabled.inverter_1/grid_charge = Disabled.Open the metrics page in the browser to see the current value is what you set, or look under configuration in SolarAssistant it self.
