Does FYXO work with Vaillant?Yes. Vaillant is a live FYXO integration. FYXO reads your Vaillant heat pump status and factors it into price-aware planning so you can lean on cheaper hours for heating and hot water.
What can FYXO do with my Vaillant device?Read (heat pump status). FYXO connects via Access token (bearer) and schedules around live wholesale electricity prices while always respecting your ready-by times, minimum charge levels and temperature limits.
Do I need any new hardware?No. FYXO connects to Vaillant through its existing API — there's nothing to install and no electrician required. Setup takes about 3 minutes.
How much does FYXO cost?Free to start with one device. Paid plans start at €8/month, plus a performance fee (15–20%) charged only on verified savings. If FYXO doesn't save you money, you don't pay the fee.
