width="20%"> </figure> <p>Do you already have a dynamic electricity tariff? Tibber is one of the first providers to offer such a tariff in Germany. I&rsquo;ve been a customer since October 2022, and it&rsquo;s been a thoroughly positive experience. Tibber offers a clearly structured, modern app where you always have full oversight of your electricity tariff and costs. Pricing is very transparent: Tibber only charges what electricity actually costs on the exchange at any given moment (plus standard grid fees, etc.), plus a service fee of just €3.99 per month.</p> <p>If Tibber sounds like an option for you, I&rsquo;d be glad if you sign up via <a class="link" href="https://invite.tibber.com/vkccaupl" target="_blank" rel="noopener" >my referral link</a>. That gets both you and me <strong>€100 for the Tibber Store</strong>, where you can buy various IoT hardware for your smart home. If you&rsquo;re already a Tibber customer and haven&rsquo;t used a referral link, you can <a class="link" href="https://support.tibber.com/de/articles/4601431-tibber-freund-innen-bonus#h_ae8df266c0" target="_blank" rel="noopener" >still do so within 14 days</a> — use code <code>vkccaupl</code>.</p> <p>Have questions or still unsure? Don&rsquo;t hesitate to reach out. I&rsquo;m happy to help you figure out whether Tibber is the right choice for you.
