Title: remotely controlled geyser Post by: roby on February 06, 2016, 01:11:27 PM hi friends, i want to make a wifi controlled 3 pin multi plug type device which can be switched on and off remotely, so that i dont need to walk a long way to turn it on every morning
Please suggest any other modules which will be cheaper/better over it also any ideas for power switching circuit will help Title: Re: remotely controlled geyser Post by: sauank on February 06, 2016, 01:47:28 PM You can use HC-05 Wireless Bluetooth RF Transceiver arduino Module

You will be able to control it via a dedicated app or via web browser in your phone it self ! Using an RPI is also an option ! If you can describe what you actually want bit more deeper i can answer deeper Title: Re: remotely controlled geyser Post by: roby on February 06, 2016, 08:20:32 PM hi arun, arduino with wifi and relay is exactly what i am talking about, thought of using ardudroid
I want to make a 3 pin multipin adapter which can be operated wirelessly so that i can connect all my ac equipments externally with an app/browser Title: Re: remotely controlled geyser Post by: roby on February 06, 2016, 08:21:28 PM sauank thanks for the info, but i'm looking forward to wifi controls
Title: Re: remotely controlled geyser Post by: a3ruz on February 06, 2016, 09:22:49 PM by three pin multi pin multi pin i think you are talking about three individual controls , ie three sockets ( three different appliance )
next is to fix your platform Arduino / RPi which one you prefer Title: Re: remotely controlled geyser Post by: roby on February 06, 2016, 09:26:52 PM i prefer arduino and i can handle ide, never worked with rasberry pi
by 3 pin multipin i meant 3 pin normal socket(just 1) Title: Re: remotely controlled geyser Post by: lastRites on February 06, 2016, 09:57:31 PM Put a high capacity relay on the live wire. Ensure clean power supply to the arduino. Bluetooth is not very reliable.. Wifi is a better alternative. But if you willing to have a separate remote, use the nrf24L01 modules. No headache of wifi, simpler control and less susceptibility to electrical noise.

http://randomnerdtutorials.com/esp8266-web-server/ check out the above - this uses nodemcu ... it is easy . I have personally done this and can confirm this works. just use a transistor and solid state relay to switch power. another option is to get one of these http://www.amazon.in/Frontier-Digital-Timer-programmable-TM619H2/dp/B00NBU5DG2?tag=googinhydr18418-21 and set it so that your geyser switches on and off at particular times Title: Re: remotely controlled geyser Post by: a3ruz on February 06, 2016, 10:10:36 PM @Roby as saikat said you can check out his first URL !
but i think you can't operate this as alone ( not sure about this ) you must connect your ESP8266 to an existing wifi network , eg your home network then your phone must be also connected to the same network , you will be using modules IP to control Title: Re: remotely controlled geyser Post by: saikat on February 06, 2016, 11:00:12 PM actually you can operate the esp8266 alone .... that is it will create its own wifi network
just set it up as an access point instead of a station. read the nodemcu Lua code snippets . once it creates its own network it is a simple matter of logging in to the network with your cellphone and pointing a browser to the ip address. Title: Re: remotely controlled geyser Post by: roby on February 07, 2016, 01:04:18 AM thanks saikat, last rides , arun
will try it and update Title: Re: Post by: a3ruz on February 07, 2016, 01:41:02 AM Thanks for that info @saikat
