The ECG PowerApp is useful only after it knows which meter belongs to your house. Until you add that prepaid number and the app returns the registered name, every “Buy Credit” tap is a guess. People skip this step while they still have units, then spend Sunday night photographing a dusty metal plate with a torch.
This article is about adding a prepaid meter, not a postpaid account. Those are different products inside the same login. Mix them and you can clear a bill that is not yours, or generate a token for a number you never intended. This site does not take the payment. PowerApp, ECG’s own USSD (*226#), and everyday checkouts such as *714*22# or ewalepay.com all sit in front of the same vending engine.
Add the meter while the lights still work
Open PowerApp on a day with data and a working SIM. Log in with the Ghana number that actually receives SMS. If the one-time password never arrives, dial *713*414# within a few minutes and read the OTP there. Do not start a second signup on a different number just because the first SMS is slow.
Look for Add Meter, My Meters, or a similar plus icon. Choose prepaid when the app asks. Type the meter number exactly as it appears on the plate or on the customer interface unit (CIU) in the kitchen. Ghana prepaid numbers are long; a single swapped digit is a gift to another household. After you submit, wait for ECG’s system to send back a name. That name is the whole point of this screen.
If the name is not the landlord, the tenant who signed the form, or the person whose ID was used at installation, stop. Do not save it “just to see if credit goes through.” Credit that goes through on the wrong meter is gone.
Where the number actually lives
The number you need is not the one on an old paper receipt from a street vendor, and it is not the MoMo wallet of the last person who “helped.” It is stamped on the meter body, often on a silver or white sticker, and it is usually repeated on the CIU if the meter itself is locked in a corridor box.
Tenants in compound houses should photograph that plate in daylight. Store the photo in a gallery album named ECG, not in a WhatsApp thread that will be cleared. If two meters sit on the same wall, photograph each plate with a landmark in the frame (the blue door, the water drum) so nobody top-ups the neighbour after a funeral weekend.
Some older NURI or split meters show a customer number that is not the vending meter number. If PowerApp rejects the digits, try the other printed string once, then call 0302 611 611 with the photo rather than cycling random lengths. USSD paths fail the same way: *226# and *714*22# also need the vending number, not a guess.
What a successful add looks like
A saved prepaid meter in PowerApp should show:
- The meter number you typed.
- A customer name returned by ECG, not a name you invented.
- A label you can edit (for example “Upstairs 3” or “Shop”) so a landlord with several points does not tap the wrong row at 11pm.
- A prepaid badge. If the row says postpaid or “account,” you added the wrong product.
Buy a small amount once after saving, in daylight. Confirm that a token SMS arrives and that the meter LCD adds units. That test is cheaper than discovering a wrong number when the fridge is already warm.
Names that should make you abort
ECG’s name lookup is not a courtesy. It is the last adult in the room. Abort if you see:
- A company or school you do not occupy.
- A former tenant who left last year, unless you are still on that service contract and everyone agrees.
- A blank or truncated name with no resemblance to the household.
- Your own name on a number you did not photograph from your wall — that can happen if you mistype into someone else’s similar sequence.
Landlords who vend for several rooms should add each meter under one PowerApp login only if they are the ones paying. A tenant who pays their own units should not share that login. Refunds, wallet balances, and transaction lists follow the app account, not the room.
When PowerApp will not save the meter
The app can refuse a number for boring reasons: no data, ECG’s lookup timed out, you are on a VPN, Play Services is stale, or you selected postpaid by accident. Retry once on a stable connection. If lookup still fails, the meter is not necessarily dead. Dial *226# and use ECG’s own add-or-buy flow if you already registered there. If you want a keypad path that shows the registered name before MoMo debit, *714*22# and ewalepay.com are the everyday backup this blog prefers when the app is the problem.
Do not install a third-party “ECG meter finder” APK. Those apps ask for SMS permission and then harvest MoMo prompts. PowerApp from Google Play or the App Store is the official storefront. USSD does not need a storefront at all.
Dual-SIM phones cause a quieter failure. You log in with SIM A, but data runs on SIM B, and the lookup hangs. Put the ECG login number in the slot that can both send USSD and receive SMS, or turn off the idle SIM for five minutes.
After the meter is on the list
Repeat top-ups should be a tap on the saved row, not a retype of eleven-plus digits in the dark. Still read the name every time the amount screen appears. Saved does not mean frozen: ECG can transfer a meter, a landlord can swap a dead unit, and a shop can keep an old number on a faded sticker.
If you sell the house or leave the room, remove the meter from PowerApp so the next occupant does not inherit your one-tap habit. They will still need their own login and their own confirmation of the plate.
Tokens remain the product. PowerApp will later show a receipt and, on most keypad meters, a token that is usually twenty digits. You type that token on the CIU or keypad. Saving the meter does not load units by itself.
FAQ
Can I add a meter I do not own yet?
Only if you have the number and the name comes back as the person who should receive the credit. Adding a friend’s meter so you can “help later” is how refunds and arguments start. Prefer they save it on their phone, or you pay once on USSD with the name on screen.
Does adding a meter cost money?
No. Lookup and save are not a purchase. MoMo is not involved until you choose Buy Credit. If a prompt asks for a PIN at the add-meter step, you are in the wrong menu or a fake app.
I added it on PowerApp. Do I still need *226#?
Yes, as a spare official door. PowerApp needs data and OTP. *226# does not. Keep *714*22# as well if you want one code that still works on a feature phone when both official doors jam. The meter does not care which channel issued the token.
The app saved a name that is almost right. Should I continue?
Almost is not enough when the difference is a brother, a shop next door, or a previous occupant. Call 0302 611 611 or visit the district office with ID and the plate photo. Do not “test” with GH₵50.
Adding a prepaid meter is unpaid homework. Do it once, in light, with the plate in your hand. Then PowerApp is a shortcut. Until then it is only an icon.
