This binding integrates the Sun Synk Connect web services. This binding is used to connect your openHAB system with Sun Synk Connect (where you log in and find Your Inverters). The binding supports discovery via configuring your login and password in an openHAB bridge. From the binding, you will get status of your inverters and also command channels where you can control them. Since the binding uses a polling mechanism, there may be some latency depending on your setting regarding refresh time.
You will require to have installed a Sun Synk inverter with a WiFi Data logger e-linter connected to the Sun Synk App or Connect. See Data Logger set up or Sun Synk Web. It is recommended, but not necessary that the "data interval" of your Gateway is set via Sun Synk Connect to 60s for best time latency. If you do not have that setting available you can request it set via Sun Synk or your installer or you can ask for an User Level Access Change Request
This binding uses your Sun Synk Connect credentials to access Sun Synk's web services via an OpenHAB Bridge (SunSynk Account). The bridge manages the account authentication and the discovery of SunSynk Inverters.

| Name | Thing type | Supported Thing |

| SunSynk Account | Bridge Thing | account |
| SunSynk Inverter | Thing | inverter |
- Add the sunsynk binding.
- Add a new thing of type SunSynk Account via the SunSynk Binding and configure with username and password.
- Go to Inbox press [+] and via the SunSynk Account start discovery [Scan] of inverters.
- Inverters should appear in your inbox!
The SunSynk Account bridge thing will discover connected inverters through the UI Scan service. When using the UI Scan service all the parameters for an Inverter Thing are discovered.
- Inverter Serial maps to the Sun Synk Connect inverter serial number
- Inverter Name maps to the Sun Synk Connect inverter alias
- Refresh time (advanced) default 60s; determines the interval between polls of Sun Synk Connect. A value above 60 is enforced. When setting this remember your inverter values are only published by Sun Synk Connect at the rate set by "data interval".
The refresh rate is limited to once every 60s to prevent too many requests from the Sun Synk Connect API, although there is no rate limit, the Sun Synk data is fully refreshed at the "data interval" set in Sun Synk Connect, at best that is every 60s. This can mean the data in openHAB is more than 1 minute delayed from real-time. Commands sent (from openHAB) to Sun Synk are buffered up until the next refresh interval and as they take a while to propagate through to your inverter, some channels are not refreshed (read back) from Sun Synk Connect until the next minute.
The SunSynk Account requires the user e-mail address and password used to login to Sun Synk Connect.
- The bridge Thing UID is of the form sunsynk:account:abcdef1234
- The inverter Thing UID is of the form sunsynk:inverter:abcdef1234:<gateway serial><inverter serial>
where <gateway serial> and <inverter serial> are discovered from Sun Synk Connect.

Only the time portion of the DateTime item is important.
Be sure to understand the time zone set up for the inverter, this can either be synchronised with Sun Synk servers, which in the UK at least applies daylight saving, or free-wheeling locally. The times set in the DateTime items using the widget are not adjusted to any time zone and are sent to the SunSynk API as Strings where they will be applied directly to your inverter. This is in contrast to other solar / energy APIs that use Zulu (GMT) time.
Place the .jar file into your addons directory. See the "Through manually provided add-on" section of Installation of Add-ons.
This first version of the binding has been built against 4.2.0-SNAPSHOT - Build #3989, currently its only available as a .jar file
org.openhab.binding.sunsynk-4.2.0-SNAPSHOTAlthough the binding is written to find multiple Inverters for each Sun Synk Connect account, testing has been against an account with a single inverter.
Sun Synk account and inverter versions are:
- Gateway Model EESW-D205
- Gateway COMM Type Wi-Fi
- Gateway HW AEW2-0005-03
- Gateway SW 4790123B24R
- Inverter 8.0 kW
- Inverter Type Energy Storage
- Inverter SW M 5.3.8.4 / S 1.5.1.5 / C E.4.3.0
- Connect App Version 1.11.12
After installation, to gain further information on any issues you encounter you can turn on Debug Logging either through the karaf console or through the openHAB UI.
Via Console:
log:set DEBUG org.openhab.binding.sunsynkVia UI:
Log on to your local openHAB as admin and follow the menus.
- Settings > Add-on-Store > Bindings
- Scroll down to find the binding and click on its title, click the cog and select the level "Debug" on the right.
You should now be able to see debug data in the openhab.log.
For those that are interested the source code is here.
