Dear Forum, I have an Arduino controlling my hot water service (the system). Normally communication with the system is via a serial USB connection to an Android device, or a windows device using the drivers provided in the IDE. Either way I have to be outside the house physically connected to the system.

I would like to purchase an interface to enable me to connect to the system via wifi. Ideally without undertaking any software or hardware development, just configuration of the new device.

Any assistance is appreciated. Thanks in advance.

I suggest, then, that what you need to do is hire a programmer. You can't possibly add hardware to the Arduino, and just expect it to magically do everything you expect it to do.

What app are you using on the Android device?

Don't you mean inside?

If you do add a WiFi module (such as an ESP8266 - perhaps in the guise of a nodeMCU) to your Arduino will it be able to connect to the external internet, for example via a router within the house?

And if it can do you know how to make contact with that WiFi module over the internet - this is not an Arduino problem.

Right now with his present system, he has to be outside physically connected to Arduino to do what he wants.

Does that imply that the hot water service is outside?

Or has my brain taken a holiday?

Can you explain what 'system' your talking about and how you currently interface with it. Does it have a USB port or are you using some sort of interface cable to to convert to USB.

Where outside the house and how far away?

Do you have a means of power out there for powering an Arduino?

Are you just reading the system or are you also sending commands/data to it?

How to you currently interface with the system to read/send data. Does your PC/Android us a custom app or are you working with raw data (what is this raw data)?

Not sure what he means by "hot water service".
I was thinking he had some sort of custom hot water system for some unknown purpose.

I don't know of anything with my hot water heater itself that can be controlled by an Arduino.

As he has decided to return with further information, we won't know.
