About Shelly Boiler Status & Control
Displays in Chrome whether the water heater connected to Shelly is on, allows turning it on/off, and reminds you if a manual activation has remained active for one hour.
# Smart Water Heater Directly from the Browser - Convenient, Fast, and Safe Control of Your Electric Water Heater
How many times have you remembered too late that the water heater was left on?
How many times have you wanted to turn on the water heater remotely, set an automatic shutoff time, or simply control it in an organized way without running to the wall switch?
This is exactly why **Ok Net’s** smart water heater control solution was created - a simple and convenient system that allows you to control your electric water heater in a smart, organized, and clear way, directly from the browser.
No need to deal with unnecessary apps.
No need to open dozens of screens.
No need to remember to turn it off manually.
Open the control interface, choose an action - and the water heater is under control.
## What is it?
This is a smart water heater control extension / interface, based on a smart device connected to the water heater, enabling control through the browser.
The goal is simple: to make the water heater more convenient, smarter, and safer for everyday use.
Instead of the usual situation where the water heater is turned on and forgotten, here you can set in advance how long it should run, turn it on when needed, turn it off immediately, and clearly monitor its operating status.
## Control - Directly from the Browser
One of the main advantages of the system is that it is designed for convenient use through a browser.
No need for a heavy app.
No need to rely on a specific phone.
No need to struggle with unfamiliar interfaces.
Open the control page and clearly see:
* Whether the water heater is on or off
* How much time remains for the current activation
* Immediate turn-on option
* Immediate shutoff option
* Option to add time
* Option to set activation for a defined duration
* Option to manage scenarios and schedules
Everything is simple and clear, without unnecessary clutter.
## Timed Activation - Without Forgetting the Water Heater On
Instead of turning on the water heater and hoping to remember to turn it off, the system is built around a much better idea:
every activation is for a defined duration.
For example:
* Turn on for 30 minutes
* Turn on for 60 minutes
* Turn on for 90 minutes
* Turn on for a custom duration
When the defined time ends - the water heater turns off automatically.
It is convenient, saves electricity, and reduces the constant concern of “Wait, did we leave the water heater on?”
## Add Time with One Click
One of the important things about the system is that it does not work in a simplistic “on or off” way only.
If the water heater is already on, you can add time to the current activation.
For example:
the water heater is on for another 20 minutes, and you want to add another half hour.
Instead of turning it off and on again, you simply add time.
This keeps the control natural and convenient, just like people actually use a water heater at home.
## Immediate Shutoff
Of course, the water heater can be turned off immediately at any time.
It does not matter whether it was activated manually, through the browser, through a schedule, or through a physical button - the interface lets you see the current status and turn it off on the spot.
It is a small function, but in practice, it is one of the most important ones.
## Integration with a Physical Wall Button
The system does not necessarily replace the regular wall switch.
On the contrary - it can work together with a physical button.
This means that someone standing near the water heater or near the switch can still use a regular button, while also enjoying smart control through the browser.
It can be configured so that a physical button press activates the water heater for a defined time, for example half an hour, instead of simply turning it on indefinitely.
This way, even people at home who do not want to deal with a computer or browser can activate the water heater easily - while still benefiting from automatic shutoff.
## Fixed Schedules
In addition to manual activation, fixed schedules can be created according to need.
For example:
* Turn on in the morning at a specific time
* Turn on in the evening
* Automatic shutoff in any situation
* Different activation scenarios by day
* Fixed operating times for the family
The goal is for the water heater to work exactly when needed - and not beyond that.
## Scenarios and Profiles
With a system like this, several operating modes can be created according to the needs of the home.
For example:
* Regular mode
* Winter mode
* Summer mode
* Busy family mode
* Saving mode
* One-time activation mode
Each profile can include different activation times, different durations, and different behavior for the water heater.
This allows the water heater control to match real life, instead of relying on a simple switch that knows nothing.
## Electricity Savings
An electric water heater is one of the appliances that can consume a lot of electricity if left on.
The system helps save in several ways:
* Automatic shutoff after a defined time
* Preventing overly long activations
* Remote control in case someone forgot to turn it off
* Smart schedules
* Activation only when truly needed
It is not magic, but it is exactly where smart control can save money over time.
## Everyday Convenience
Beyond saving electricity, the main benefit here is convenience.
No need to get up.
No need to check whether the water heater is on.
No need to call someone at home to turn it off.
No need to worry that you forgot.
Everything is in one place, with a clear interface.
## Especially Suitable for Netfree Users and Filtered Environments
One of the important directions of this system is compatibility with browser-based use and filtered environments, without dependence on problematic apps or incon…
