Convert Geyserwise to Smart WiFi

Upgrade an Existing Geyserwise System to Full Smart WiFi Control

If you already have a Geyserwise controller installed (such as a TSE or older non-WiFi model), you do not need to replace your entire geyser system to gain smart functionality. In most cases, it is possible to convert or upgrade Geyserwise to Smart WiFi, giving you mobile app control, remote monitoring, and intelligent scheduling without starting from scratch.

This page explains what conversion means, which systems qualify, what hardware is required, how the upgrade is performed, and what performance improvements to expect. It is written to support an informed decision at the same time as booking a professional installation.

What Does “Convert Geyserwise to Smart WiFi” Mean?

Conversion refers to upgrading a non-WiFi or limited Geyserwise controller to a Geyserwise Smart WiFi–enabled system, typically by replacing the control unit while retaining the existing geyser, sensors, and compatible wiring.

In practical terms, this means:

• Removing the existing Geyserwise controller (e.g. TSE / TSE1)
• Installing a Geyserwise Max Smart WiFi controller
• Reusing compatible temperature probes and element wiring where allowed
• Connecting the system to the Geyserwise cloud and mobile app

The result is full smart control without changing the geyser cylinder or heating method.

Which Existing Geyserwise Systems Can Be Converted?

Convertible Systems

Most of the following installations can be upgraded:

• Geyserwise TSE
• Geyserwise TSE1
• Older Geyserwise Max (non-WiFi)
• Geyserwise units paired with basic timers

Systems Requiring Assessment

A site inspection is required if:

• Sensors are damaged or non-standard
• Wiring does not meet current SANS standards
• The system is integrated with solar, heat pump, or gas boosting

A professional assessment ensures the upgrade is safe, compliant, and cost-effective.

Geyserwise Smart WiFi Product Used for Conversion

Geyserwise Max Smart WiFi

This is the primary controller used when converting to Smart WiFi.

Key features include:

• Built-in WiFi module (2.4GHz)
• Cloud-based monitoring
• Mobile app control (Android & iOS)
• Intelligent temperature-driven heating
• Fault detection and alerts
• Solar and heat pump compatibility

This controller replaces the existing unit and becomes the central brain of the geyser system.

Mobile App and Smart Control Explained

After conversion, the geyser is controlled through the Geyserwise Smart App, available on:

• Android (Google Play Store)
• Apple iOS (App Store)

What You Can Do in the App

• View real-time water temperature
• Switch heating on or off remotely
• Set daily and weekly heating schedules
• Optimise heating around load shedding
• Receive alerts for faults or overheating
• Monitor historical heating behaviour

The app communicates securely with the controller via the Geyserwise cloud platform.

If WiFi or Internet Is Down

• The geyser continues operating on stored schedules
• Safety and temperature limits remain active
• Remote access resumes automatically when connectivity returns

How the Conversion Is Performed (Professional Process)

Converting to Smart WiFi is not a plug-and-play task. It requires electrical, system, and configuration expertise.

Step 1: System Assessment

• Confirm geyser type and capacity
• Inspect existing Geyserwise controller
• Verify sensor and wiring compatibility
• Identify integration with solar, heat pump, or gas systems

Step 2: Electrical Upgrade (Qualified Electrician)

• Isolate power supply
• Remove existing controller
• Install Geyserwise Max Smart WiFi
• Ensure compliance with SANS 10142

Step 3: Plumbing Verification (Licensed Plumber)

• Confirm correct sensor placement
• Check pressure and temperature components
• Ensure no leaks or thermal stress points

Step 4: WiFi and App Configuration

• Connect controller to 2.4GHz WiFi
• Register device on Geyserwise cloud
• Pair with homeowner’s mobile app
• Configure schedules and recovery logic

Step 5: Testing and Handover

• Verify heating cycles
• Test remote commands
• Demonstrate app usage

Compatibility With Different Geyser Types

Standard Electric Geysers

• Most common conversion scenario
• Full Smart WiFi functionality

Solar Geysers

• Smart WiFi controller prioritises solar input
• Electrical boosting only when required
• Best installed by an experienced solar geyser installer

Heat Pump Geysers

• Coordinates heating cycles for efficiency
• Reduces compressor wear
• Improves long-term system performance

Gas-Assisted Systems

• Can operate alongside gas boosters
• Requires coordination with a registered gas installer

Performance Gains After Conversion

Typical benefits include:

• Reduced electricity consumption
• Improved hot water availability
• Remote visibility and fault alerts
• Better performance during load shedding

Safety, Compliance, and Insurance

Improper upgrades can result in:

• Electrical hazards
• Controller damage
• Insurance claim rejection

Professional conversion ensures compliance with:

• SANS 10142 (Electrical)
• Manufacturer specifications

Certificates of Compliance (CoC) can be issued where required.

Frequently Asked Questions

Do I need to replace my geyser to upgrade to Smart WiFi?

No. In most cases, only the controller is replaced. The existing geyser remains unchanged.

Can any Geyserwise be converted?

Most non-WiFi Geyserwise models can be upgraded, subject to a compatibility assessment.

Will I save electricity after converting?

Yes. Smart WiFi control typically reduces unnecessary heating cycles and improves efficiency.

Does conversion work with solar geysers?

Yes, when installed and configured by a technician experienced in solar geyser systems.

Is WiFi required all the time?

WiFi is required for remote access, but the geyser continues operating on schedules if connectivity is lost.
