My Solar provides quick and easy access to up-to-date statistics for your home solar installation on iPhone and Apple Watch. Todays latest statistics are available direct in the app, via home and lock screen widgets, through notifications and also with Siri. My Solar currently supports installations with Solis inverters. Data is retrieved via the Solis Cloud API (freely available from Solis on request) or by using the open-source Solis Cloud Scraper project. Details for both are available in the app. Future versions will support different manufacturers inverters. The My Solar app presents current power generation statistics, showing you details for solar yield, electricity consumption and both battery and grid usage. In addition it also presents the same statistics for the day so-far. My Solar gives you at-a-glance access to your data by exposing information through widgets that can be directly installed on your iPhone home and lock screens or complications to use on your Apple Watch face. A variety of widgets are available to show individual or combined statistics, including current solar yield, current battery charge, electricity distribution, inverter temperature and a daily summary. Widgets refresh automatically to show the latest data. My Solar can also give you both a current and daily summary via Siri on all devices. Just ask "Hey Siri, display current stats from My Solar" for the current data or "Hey Siri, display todays stats from My Solar" for a summary of today so far. My Solar can notify you when your home battery discharges to a certain percentage, e.g when it reaches its minimum discharge level. It can also notify you when your home battery reaches a certain charge, e.g when you're approaching a full battery. You're also able to set an inverter temperature threshold to be notified about. With My Solar you can control the charge and discharge settings of your inverter. This is ideal if you have a cheaper overnight tariff and want to charge your batteries ready for the next day, or discharge batteries via a feed-in tariff. It's accessible right from the front screen and is simple and easy to use. You'll need to contact Solis for access to the appropriate API, but that is very straightforward and details are included in the app. My Solar will verify you have the correct API access before it allows you to purchase this upgrade, so you can have confidence your setup is correct. My Solar can even remind you to update these settings on a daily basis. My Solar will also synchronise your inverter timer with your iPhone. No more fiddly setting via the inverter, simply tap the button in My Solar and your inverter clock will be synchronised with your iPhone. You can also schedule a weekly background sync, so you never have to check again. The My Solar app presents clear current and daily statistics on both iPhone and Apple Watch. The iPhone app is where you configure your Solis Cloud API or Solis Cloud Scraper login details.

Havenwise is an easy-to-use control and optimisation system for your heat pump. Connect via our app in just a few minutes, no installer needed! We connect directly to your internet-connected Vaillant, Mitsubishi or Samsung heat pump, so most users need no extra hardware. Havenwise automatically learns how your home heats up and cools down. Our smart software takes into account your energy tariff, local weather, and your comfort to keep your home warm and water hot for the lowest possible bill. Havenwise works great with time-of-use tariffs to shift your heating out of expensive peak periods and into the cheapest times of day. For homes with solar panels, we can shift usage to warmer and sunnier periods. For batteries, time-of-use optimisation can be toggled on and off depending on your preference, to take advantage of tariffs or keep your heat pump running low and slow for maximum efficiency. Our excellent support is always available to answer questions and keep you informed and confident about your home heating needs.
