Show HN: WattSaver for Octopus Energy, smart scheduling for electricity devices

3 points by thenewrohirrim 8 hours ago

Hi, I'm a long time lurker, first time poster here. I switched to Octopus Agile in August and found it tricky to schedule my less smart devices to run during cheaper times as i had to calculate when to do so every time. We (we're a husband and wife team) created an app, WattSaver, to help us do this. You can use the app to find the cheapest time to run any device by telling the app how long the device will run for. We use it to run immersion heaters, dishwashers and washing machines. If your device has a "finish in" or a "delayed start" button, WattSaver will calculate those numbers for you too. You can also put a maximum end time, if you want to ensure your dishes will be clean by the morning for example. We've estimated we've saved quite a bit over the past 3 months by using a version of this. It's available for all apple devices (mac, iphone, ipad and apple watch). The app's available as a cheap lifetime / outright buy. We're in it for the long haul, our other app (CycleMaps) has been available for over 13 years now.

It's available from the app store here, some more info on our website. I hope this is useful, we welcome any feedback!
