Frequently asked questions

  • How does Synergi Smart Climate work?

    To use Synergi Smart Climate, you set a preferred indoor temperature and Synergi handles the price and temperature optimization. The optimization works as follows:

    • Before high-price hours, your device uses cheap electricity to heat above or cool below your preferred temperature. During high-price hours, your device conserves energy, heating below / cooling above your preferred temperature. At other times, your devices keeps your preferred temperature. When prices are low for the whole day, we simply keep your preferred temperature.
    • Synergi uses local real-time electricity prices to optimize your heat pump temperature automatically. As the smart feature develops, we will add more options for temperature customization and electricity prices for you to get better insights into our suggested optimization.

    PS: Please note that your device maintains the temperature according to our optimization and is not powered off at any point. Moreover, the prices that you see in the app do not include taxes or your energy provider’s margin.

  • What types of heating & cooling devices do you support?

    We currently support heat pumps, AC remote controllers, and smart heaters. There’s two ways to use the smart climate feature:

    Via Sensibo: We can support all air heat pump devices via a Sensibo (AC remote control device). This helps us connect to the cloud of your Sensibo so we can control your heat pump remotely.

    Via wifi-enabled heat pumps: We natively support WiFi-enabled Mitsubishi, Panasonic, Adax, and Toshiba air heat pumps. Also, Wifi-enabled Adax heaters. If yours is on that list, you’re good to go. We will add native support to more heat pump brands in the near future. For example NIBE, Daikin, Bosch, and Viesmann.

    Additionally, we hope to support other type of heating and cooling devices (radiators, thermostats) in the near future.

    You can follow updates on new device support from our changelogs pinned to the website.

  • What do I need to connect my heating and cooling device to Synergi?

    If you have a WiFi-enabled Mitsubishi, Panasonic, and Toshiba heat pump or Adax heater, then nothing extra is needed. If your unit is not WiFi-enabled, then you’ll need a Sensibo device. You can purchase a Sensibo from the Synergi webshop.

    Native support for other heat pump brands like NIBE, Daikin, Bosch, Viesmann are coming soon. You can follow updates on new device support from our changelogs pinned to the website.

  • How much can I realistically save with Synergi Smart Climate?

    According to Motiva, you could reduce your energy bills by five percent by lowering the heat pump temperature by one degree Celsius during the heating season. Additionally, using electricity during cheaper hours contributes to increased savings, which could sum up to 20% of total heat pump electricity costs.

  • How will optimizing heat pump temperature affect the performance of other heating devices at home?

    When Smart Climate lowers your heat pump temperature automatically, this could make other heating devices in your home work harder. The savings you can expect will be more significant when heat pumps are your primary source of heating and cooling at home.

  • Should I use Smart Climate when the prices are unusually high?

    There might be situations when the real-time electricity prices are unusually high. If those moments arise we recommend that you switch off your devices for maximum savings. Keep in mind that if you turn off your heat pump during a period of extreme frost, it is recommended that you wait until the temperature has warmed up before turning on the heat pump again.

  • Can I use Synergi Smart Climate in a remote location that’s not my primary residence?

    You can use Synergi Smart Climate in any of your private residences and manage those remotely. However, we recommend that the location is close enough if, within short notice, you need to turn on/off your device manually. In addition to Smart Climate we also recommend having other heating sources for remote locations.

  • Do I have to pay to use the app?

    If we don’t support your wifi-enabled heat pump and you want to use Synergi Smart Climate, we highly recommend getting a Sensibo device to connect any heat pump brand to Synergi. You can buy your own from Synergi’s own web shop.
