I searched the internet hi and low. Can’t find any wifi connected I/O controller to just monitor the High or Low state or On and Off input of something. Is there anything like that available?
What protocol does the device you want to monitor support? HTTP, TCP, something else?
What make/model is the device?
Maybe Shelly devices are solution for your need
When you say you just want to “Monitor“ what do you mean? Do you want to be able to actuate the device, that is, turn it on and off? Or do you just want like an indicator LED that tells you if it is on or off?
And, yes, as @TapioX suggested, Shelly is probably your best bet in either case if you’re willing to wire a device inline, but the exact model will depend on what you want to do with it.
Otherwise, as @h0ckeysk8er noted, if you want to do this without wiring and just get notification, it will depend on the communication protocol that the monitored device is using.
I have a borehole pump that is on a sonoff inching switch that I control via Google home or ewelink. The water tank is quite far from the pump so running cables all the way is out of the question. I would like to connect someting to the float level sensor that has a NO/COM/NC switch inside to monitor the water level. It just needs to send a signal via Wifi to Google home or ewe link when the pump needs to start and stop according to the level. I will build the scenes and routines myself. just need someting that can send a signal as on or off or high or low state to one of these 2 apps
Will this be wired to power or were you looking for something batteryoperated? Not many batterypowered Wi-Fi devices because Wi-Fi uses so much power relative to zigbee or Z wave.
Also, just so you know, this forum is for people who are using the Samsung SmartThings ™ home automation platform, so all of the questions and answers are assumed to be in that context. Everyone is welcome here, it’s just that you may get a wider range of answers if you ask on a more general home automation board.
There is power available. So it does not have to be battery operated
Thanks for the heads up. I guess Smartthings will do as well. Most of my appliances and phone is Samsung. I am not bound to google home or ewelink. I just had the device lying around and thought I can automate the pump not having to run back and forth getting the tanks full
