Managing Everything in the Ostrom App
The Ostrom App gives you full control over your energy contract: track consumption, submit meter readings, adjust your monthly deposit, and manage your account – all in one place, no waiting around.
🚀 Why Use Self-Service?
With self-service, you handle things instantly and save time. You stay in control of your contract – and we can focus on the requests that need more attention.
💡 There's a lot you can do directly in the Ostrom App without waiting for our support team, for example:
Rewards: View referrals
Account: Change password, manage push notifications, update personal details, request a security code via SMS, change language
Contract: Change contract name, create an additional contract, submit a cancellation, edit billing address, view current and past prices
Meter reading: Submit and view meter readings
Payments: Change payment method, adjust monthly deposit, view payments, view and download invoices
💶 Adjust Monthly Deposit
Ostrom App: Home/More → Payments → Adjust deposit
No app access? Send us the amount you'd like in the chat – we'll update it for you.
💡 The monthly deposit can only be adjusted for SimplyFair, SimplyFair12, SimplyFair24, or SimplyDynamic Monthly. The SimplyDynamic plan has no deposit – we issue a monthly invoice instead.
🧾 Download Invoices
Ostrom App: Home/More → Payments → Invoices
We also send every invoice automatically to your email as a PDF.
💳 Change Payment Method
Ostrom App: Home/More → Payments → Change payment method
Available payment methods:
SEPA direct debit – the amount is automatically debited from your account
Manual bank transfer – you transfer the amount yourself. A few days before the due date, you'll receive our bank details by email.
No app access or international IBAN? Send us your IBAN and account holder name – we'll take care of the change.
📊 Submit Meter Reading
Ostrom App: Home → Add meter reading
Please note:
For new contracts, submissions are only possible from the delivery start date.
Error message? Send us a screenshot.
Submitted the wrong reading? Send us the correct reading including the date.
When Do I Need to Submit a Meter Reading?
Only if you don't have a smart meter – or if we haven't received consumption data from your metering point operator yet.
With a smart meter, manual submissions are usually not needed. We automatically receive a meter reading from your metering point operator at the end of each month.
