python
Force Poll
pw.poll('/api/system_status/soe',force=True)
'{"percentage":100}'

Powerwall Alerts
pw.alerts()
['PodCommissionTime', 'GridCodesWrite', 'GridCodesWrite', 'FWUpdateSucceeded', 'THC_w155_Backup_Genealogy_Updated', 'PINV_a067_overvoltageNeutralChassis', 'THC_w155_Backup_Genealogy_Updated', 'PINV_a067_overvoltageNeutralChassis', 'PVS_a018_MciStringB', 'SYNC_a001_SW_App_Boot']

Battery Reserve Setting
pw.get_reserve()

* PyPI 0.3.0
* Added alerts and additional attributes from `vitals()` output.
* Note: API change to `vitals()` output for dependant systems.

* PyPI 0.2.0
* Breaking change to Protobuf schema (PR 2) including:
* Files `tesla.proto` and `tesla_pb2.py`
* Impacted output from function `vitals()` and [examples/vitals.py](examples/vitals.py).

* PyPI 0.1.4
* Changed "Network Scan" default timeout to 400ms for better detection.
* Added Tesla App style "Battery Level Percentage" Conversion option to `level()` to convert the level reading to the 95% scale used by the App. This converts the battery level percentage to be consistent with the Tesla App:

python
>>> pw.level(scale=True)

* PyPI 0.1.3
* Added `temp()` function to pull Powerwall temperatures.

python
pw.temps(jsonformat=True)
