Sonoff is a wireless switch which can control electronic devices such as home appliances via WiFi.<\/p>\n
It support max power of 3500W which should be enoughWhy I used sonoff pow:<\/p>\n Sonoff has aonther model called ‘sonoff TH16’ that also can handle 3500W. Sonoff pow has one momentary\u00a0button. Pressing this button will toggle the connected device on and off. Before I start writing about my installation, please note that dealing with mains electricity should What you will need:<\/p>\n I replaced the switch in the panel\u00a0with the stairway momentary button. Then I had to trim the switch connectors because they are too big and won’t let me close the panel. Next step is to track the sonoff’s switch on the pcb and connect it to the wires from the new switch. Now we have to dissemble the old panel (if you didn’t already) and connect the boiler and the\u00a0mains electricity. Connect Line\u00a0to Line (Live\/Phase) , Neutral to Neutral (Zero) and Earth to Earth. Now all you have to do is carefully close the panel and put back the power on. Download eWeLink app\u00a0for Android <\/a>or IOS<\/a>. Start it and create a new account. That’s all for today\u00a0\ud83d\ude42<\/p>\n Next goal: connecting the boiler with Amazon Echo!<\/p>\n Update:<\/span> Itead made an Alexa skill for the sonoff so it’s easy to control it with Alexa You can see how I controlled a esp8266 device with mqtt client from Alexa here: Recently I moved to a house where I don’t have a gas water heater. Now when it’s winter I need to plan my showers and turn on the boiler in advanced. Since the IOT era began, I can see more and more solutions for connecting the boiler to a smart wifi switch (switcher, SwitcHeat and …![\"\"](\"http:\/\/itay.mobi\/blog\/wp-content\/uploads\/2017\/01\/Sonoff_Pow_Wiring-300x215.png\")

\nalso nice addition to see the total cost each use\/day\/moth<\/li>\n
\nThis model does not able to measure current and unable to show the power consumption, but can also be used.
\nthe TH16 has few more connections on the board that might ease connecting it to a switch.<\/p>\n
\nLong press (5 seconds) will make it enter into a pairing mode for pairing with the app.<\/p>\n
\nbe only\u00a0handled<\/strong>\u00a0by electricians. If you does not know what you are doing, please don’t try this.<\/strong>
\n If you decide to make your own, please make sure you shut the boiler power<\/strong>
\nfrom the main switch and also check that the ‘Live’ wire is not live with a tester.
\nI take no responsibility.
\n<\/strong><\/p>\n\n
\n(If you don’t want\/need a manual control to start\/stop the boiler you don’t need this button)
\nI did this because the sonoff’s button is also a momentary push button, and like I said before – long press will put it in
\npairing mode. If I use a regular on\/off button I need to imitate this action every time.<\/p>\n![](\"http:\/\/itay.mobi\/blog\/wp-content\/uploads\/2017\/01\/DSC_0587-1024x759.jpg\")

\nAfter I trimmed them, I also soldered a wire to the switch connectors<\/p>\n![](\"http:\/\/itay.mobi\/blog\/wp-content\/uploads\/2017\/01\/DSC_0616-300x223.jpg\")
<\/a><\/p>\n
\n(again, if you don’t use the button skip this)<\/p>\n![](\"http:\/\/itay.mobi\/blog\/wp-content\/uploads\/2017\/01\/DSC_0605_2-300x168.jpg\")

\nto the sonoff. Check again that you don’t have\u00a0a live electricity!<\/strong><\/p>\n![](\"http:\/\/itay.mobi\/blog\/wp-content\/uploads\/2017\/01\/DSC_0579-683x1024.jpg\")
<\/a><\/p>\n
\nNote that the input Line\u00a0is on the right and the output Line is on the left.
\nI already had the Earth shorted so I didn’t connect it to the sonoff.
\nI also managed to break the Line connector so I soldered a thick wire straight the pcb.
\nIn addition, I\u00a0added a kapton tape on the area the new switch might touch to avoid shortening the circuit.
\nIf you have an indicator light you can connect it to the output Line and Neutral in the sonoff as well.<\/p>\n![](\"http:\/\/itay.mobi\/blog\/wp-content\/uploads\/2017\/01\/SCHEMATIC_2-1024x691.png\")
<\/p>\n
\nOne press on the switch should start the boiler, another one should stop it.
\nIf you have an indicator light you should see it turning on and off.<\/p>\n![](\"http:\/\/itay.mobi\/blog\/wp-content\/uploads\/2017\/01\/DSC_0618-701x1024.jpg\"){kind=spacer}
<\/a><\/p>\n
\nNow make a long press (5 seconds) on the switch to put the sonoff in pairing mode.
\nIn the app add a new device and enter your home SSID and password.
\nAt the end of the process you should have a new device in the app.
\nYou can now control it and see it’s power consumption, add on and off timers and more..

\nIf you want to plug it to your smart home via MQTT, \u00a0you can install the\u00a0Sonoff-Tasmota firmware
\n(but you will lose the control from their app) and control it with MQTT or HTTP requests.
