 # SolarEdge Local
 
+**Warning**
+
+Recent firmware versions disable local access.  Some units may continue to work, but many users are reporting it is no longer available.  See [this issue](https://github.com/jbuehl/solaredge/issues/124) and [this issue](https://github.com/drobtravels/solaredge-local/issues/24) for additional details.  Please check if you can access your inverter via a web browser before attempting to use this library.

 The goal if this respository is to provide information about using the local API available on some solar edge inverters.  This is a WIP based on my observations and may contain inaccuracies.  Pull Requests or Issues are encouraged to correct any mistakes or add additonal informatoin.
 
 ### Relevant Models
 
-The local API is available on the [SExxxxH-US models with SetApp](https://www.solaredge.com/sites/default/files/se-hd-wave-single-phase-inverter-with-setapp-datasheet-na.pdf) as well as European three phase inverters SEXXK-XXXTXBXX4 models with SetApp like [SE3K-E10K](https://www.solaredge.com/sites/default/files/se-three-phase-inverter-setapp-ds.pdf), [SE12.5K-SE27.6K](https://www.solaredge.com/sites/default/files/se-three-phase-inverter-setapp-datasheet.pdf) and [SE33.3K](https://www.solaredge.com/sites/default/files/se-three-phase-inverter-for-277-480-grid-setapp-datasheet.pdf). Same goes for Australian inverters [SE2500H->SE10000H](https://www.solaredge.com/sites/default/files/se-single-phase-HD-wave-inverter-setapp-datasheet-aus.pdf). 
-Please check carefully the datasheets if in the section "Additional Features", sub-section "Inverter Commissioning" is present the following line "With the SetApp mobile application using built-in Wi-Fi access point for local connection".
