Hi,
I'm running NodeRed to manage my MQTT / Tasmota home automation devices.
One of the devices turns my hot water immersion heater on and off on Economy 7.
(in case people don't know what Economy 7 is in the UK, its a cheaper rate electricity, for 7 hours overnight, to use for electric storage heaters and hot water. I pay about half price for electricity during a specific 7 hours over night.)
My NodeRed server (RPi) is installed in the UK timezone which switches between British Summer time and GMT. I use BST for other devices, like lights and garden watering.
However, Economy 7 does not use BST. It is always on GMT.
I want to set a timer to turn on the heater at 11pm and turn off at 6am GMT, irrelevant of the current local time ?
Is that possible ? If so, how ?
Thanks !
Jon,
