-# PV Opt: Home Assistant Solar/Battery Optimiser v3.8.8
+# PV Opt: Home Assistant Solar/Battery Optimiser v3.8.9
 
 Solar / Battery Charging Optimisation for Home Assistant. This appDaemon application attempts to optimise charging and discharging of a home solar/battery system to minimise cost electricity cost on a daily basis using freely available solar forecast data from SolCast. This is particularly beneficial for Octopus Agile but is also benefeficial for other time-of-use tariffs such as Octopus Flux or simple Economy 7.
