Siemens Cashpower 2000 is an industry-standard prepayment electricity meter that utilizes a split-metering system and the Standard Transfer Specification (STS)
to manage consumer electricity usage. This report details its operation, code generation, and common troubleshooting steps. 1. System Overview
The Cashpower 2000 system is comprised of two distinct components: The Meter:
Usually installed in a secure, locked outdoor kiosk to prevent tampering, this unit contains the critical measurement and load control hardware. Customer Interface Unit (CIU): Siemens Cashpower 2000 Electricity Code Generatorl
A compact keypad and display located inside the home that communicates with the meter via Power Line Communication (PLC) . It is used to enter credit tokens and monitor usage. 2. The Electricity Code (Token) Generator
The "code generator" for these meters is not a consumer-facing tool but a secure backend vending system managed by the utility provider. Token Security:
Codes are 20-digit numeric sequences encrypted using the STS protocol. Each token is unique to a specific meter's serial number, ensuring they cannot be reused or shared. Generation Process:
When a user buys credit, the vending system identifies the meter's tariff and converts the payment into kilowatt-hours (kWh), generating a one-time-use token. Key Change Tokens (KCT):
If a utility updates its encryption settings (such as for the STS TID rollover), the system generates a three-part "KCT" sequence that must be entered before normal credit tokens will be accepted again. 3. Essential User Interface Codes
Users can enter short numeric sequences into the CIU keypad to retrieve system information: Description Serial Number Displays the unique meter identification number. Instant Power Shows the current power consumption in Watts. 30-Day Total Shows total electricity consumed over the last 30 days. Power Limit Displays the maximum allowed load before the meter trips. 4. Troubleshooting and Resets
Common issues with the Siemens Cashpower 2000 often involve communication or security locks: Communication Errors:
If the CIU beeps or fails to accept codes, it may have lost connection with the outdoor meter. Ensure the CIU is plugged into an outlet on the same electrical circuit as the meter. Tamper Lock:
Some meters enter a "lock" state if they detect a load bypass or physical tampering. In these cases, no codes—even valid credit tokens—will work until a utility technician clears the lock. Firmware Reset:
To clear minor errors, some experts recommend a manual reset by pressing and holding the blue button or '#' key for 3 seconds.
For specific reset codes or if your meter is displaying a "fault" message, you should contact your local utility provider, as these codes are typically authorized only for official maintenance.
The Siemens Cashpower 2000 is a widely used prepayment electricity meter designed for residential and light commercial utility management. It allows consumers to pay for their energy upfront using a unique 20-digit STS (Standard Transfer Specification) token, which is then entered into a keypad to add credit to the meter. How the System Works Cashpower 2000
operates on a "pay-as-you-go" basis, giving users real-time control over their consumption.
The Token Process: When you purchase electricity, a vendor sends your meter number and payment amount to a central server. This server generates a 20-digit token using a secret encryption algorithm.
Code Entry: Users manually input this code via the meter’s keypad. A small internal computer "deciphers" the code to verify its authenticity and adds the corresponding kilowatt-hours (kWh) to the balance.
Split Configuration: Many versions are "split meters," where the actual measurement unit is safely tucked away in a street kiosk or pole-top box to prevent tampering, while a Customer Interface Unit (CIU) with a keypad is plugged into a standard wall outlet inside the home. Key Features and Codes
The meter includes several diagnostic codes that users can enter to check their status: 000: Displays the Meter Serial Number.
001: Shows Instantaneous Power Consumption (how much electricity you are using at that exact moment). 009: Displays the consumption for the previous 30 days.
014: Shows the Power Limit (the maximum wattage the meter allows before tripping). Troubleshooting & Common Indicators
Understanding the meter's display is essential for managing your power: "Accept": The token was valid and credit has been added.
"Reject": The token was entered incorrectly or was for a different meter.
"Used": A security feature ensures each 20-digit code can only be used once.
"Old": STS tokens typically expire after about three months if not used.
Beeping/Alarm: An audible tone often warns when credit is reaching a critical low level. Maintenance and Upgrades Siemens Cashpower 2000 Reset & User Guide - JustAnswer

It utilizes the Standard Transfer Specification (STS), a global standard for transferring electricity credit via 20-digit encrypted tokens. 2. The STS Token Generation Process
Tokens are not generated by the meter itself but by a central Vending System managed by the utility provider.
Encryption: Each token is encrypted using a unique Meter Key derived from the meter’s serial number.
Security: The 20-digit code includes a "Token Identifier" (TID) to prevent the same code from being used twice.
Transfer: Once a customer pays, the vending system generates the 20-digit code, which the user manually enters via the meter's keypad. 3. Key Meter Functions & Information Codes
Users can interact with the meter using short codes to verify status or troubleshoot: 000: View Meter Serial Number. 001: View instantaneous power consumption. 009: View consumption for the previous 30 days. 014: View current power limit in Watts. 4. Troubleshooting and Reset Procedures
Common issues often involve communication errors or rejected tokens:
Resetting Connection: Pressing the "i", "#", or Blue button can sometimes re-establish a connection between the customer interface unit (keypad) and the meter box.
KCT (Key Change Tokens): If a utility provider updates encryption (e.g., during a TID rollover), the meter may require a 3-part "Key Change Token" before it will accept new credit units.
Tamper State: If the meter detects tampering, it may enter a "Lock" state that can only be cleared by an authorized technician or utility reset code. 5. Conclusion The Siemens Cashpower 2000
remains a robust solution for decentralized energy management. While users often seek "code generators" for resets, these sequences are typically utility-specific and tied to the meter's unique security keys to prevent unauthorized energy use.

Siemens CashPower 2000 Meter Error: Troubleshooting Help
It sounds like you’re referring to a device or system associated with Siemens Cashpower 2000 — a prepaid electricity meter system commonly used in parts of Africa and Asia.
However, I must be clear:
There is no legitimate “code generator” for Siemens Cashpower 2000 meters outside of the official utility vending system.
Here’s why:
How it works — The Cashpower 2000 uses a secure algorithm (often based on the Standard Transfer Specification (STS) or a proprietary Siemens method) to generate 20-digit recharge codes. Each code is tied to a specific meter’s ID and the amount of credit purchased.
No valid offline generator — Any software or website claiming to generate free electricity codes for Cashpower 2000 is either a scam, malware, or a fake generator that produces invalid codes. Attempting to use such codes could damage your meter or get you blacklisted by your utility.
Legal & safety risks — Generating unauthorized codes is illegal (theft of service) and unsafe. Utilities monitor for invalid token attempts.
What to do if you need electricity credit:
If you’re simply curious about the protocol or mathematics behind the code generation for educational or research purposes (e.g., STS or rolling tokens), let me know — I can explain how secure prepayment token systems work in principle.
Let’s examine what those “generators” actually are.
A man sold a “Cashpower 2000 resetter” for 1,000 KES. Buyers entered the codes, and their meters either:
Many power companies (e.g., Nairobi’s Kenya Power, Zimbabwe’s ZESA, Eskom in SA) offer official apps that link to your meter. They generate tokens in real time after payment.
No legitimate “generator” exists that requires no payment.
