homebridge-hydroquebec-peak-virtual-switch

Hombridge Hydro-Quebec plug-in (integration) that relies on Hydro-Quebec's Open Data APIs to determine wether a peak period is currently ongoing and based on that, turns ON or OFF a HomeKit virtual switch.

There are actually three (3) virtual switches to represent each of the following relevant periods:

• PEAK -> An Hydro-Quebec peak period is actually ongoing
• PRE_PEAK -> Period before Hydro-Quebec peak period (typically 0am-3am and 10am-2pm)
• PRE_PRE_PEAK -> Period before pre-peak period (typically 9pm-0am and 7am-11am)

Switch states:

• ON -> The given period is currently ongoing
• OFF -> The given period is NOT currently ongoing

At any given time, only one of the virtual switches will report ON, all others will be reporting OFF.

In case of overlap, the PEAK switch wins over the other switches, and the PRE_PEAK switch wins over the PRE_PRE_PEAK switch.

With these virtual switches, you can then use HomeKit automations to turn other devices ON/OFF when any of these virtual switches change state (ON/OFF), to have even more electicity savings during these different pre/peak periods.
