Tesla Powerwall 2 Monitor

Created in RainMeter v4.1

Monitor & graph Powerwall 2 API output:
• Grid import & export
• Battery charging, discharging & level
• Home load
• PV generation
• Firmware revision
• Stored energy (kWh)
• Will graph up to 7kW import / 5kW export
• Grid shows idle / import / export states
• Battery shows idle / charging / discharging states

In later firmware revisions the Powerwall only supports SSL connections and Rainmeter cannot ignore a failing certificate, so you must create a 'powerwall' hosts entry of your Powerwall Home Energy Gateway IP address in order for this meter to work correctly


v2.6 - 2019-04-17
• HTTPS Fixes
• Version number fixes

v2.5 - 2018-04-20
• Modified graph so that graphed statistics now match up with vertical measurement intervals

v2.4 - 2018-04-11
• Added display of stored battery energy in kWh (Battery Charge % / 100) * 13.5
• Modified battery charge / grid export limits and graph for 5kW
• Added dynamic Powerwall firmware version display

v2.3 - 2018-03-25
• Adjusted graph line length by 1 pixel to improve aesthetic
• Combined BattImport & SolarPVGen histograms into a single histogram to improve aesthetic
• Further tweaks to grid state thresholds to address graph jumping during low load spikes
• Added line graphs and adjusted colours to improve PV & grid histogram meter aesthetic

• Tidied redundant meter config
• Further improvements to meter aesthetic when loads change erratically

• Added visual version identifier
• Resolved issue with undefined meter
• Optimised state thresholds and meter display triggers
• PV generation and Powerwall graphs now use histogram instead of line to improve aesthetic
• Increased home load line width to improve aesthetic when grid import and home load values match
• Reordered graph layers to improve aesthetic
