The rectangular window to the left exposes the AM2320 temperature/humidity sensor used for my Air Exchanger control function. Later in the article, when I describe the battery-powered leak detectors, I’ll detail the ways in which I reduced their power consumption.įIGURE 1 – My central controller using the ESP32 and the ESP-NOW wireless protocol. Since it’s powered by the AC line, the Controller’s power consumption (3W) is not an important factor. I used an ESP32 for the central controller hub because it contains more GPIO lines.
Finally, it would display temperature/humidity at the hub location and leak detector locations. It would also allow me to control my air exchanger and irrigation pump on/off times, using a touch-controlled 24-hour table on the display. It would give me a visual indication that all the battery-operated leak detectors were still running. This dedicated central controller hub contains a 4.3″ TFT touchscreen display, which allows for a fairly nice user interface. I felt that Google was unlikely to change the way it works any time soon, so the firmware for this project should hold up well. I planned on abandoning the IFTTT external cloud service (plus a few other cloud schemes I had tried), and instead have my dedicated Controller unit use Google’s Gmail server. I figured that I would use this protocol with a dedicated central controller hub (using an ESP32) and remote sensor/activator units. This protocol is called ESP-NOW and works equally well with both the ESP8266 and the ESP32 MCUs. With all of this in mind, I became quite interested when Espressif introduced a peer-to-peer Wi-Fi communication protocol that promised a very short connection time. While the ESP8266/32 MCUs have low-power sleep modes, when they “wake-up” and connect to your wireless access point, the amount of time it takes to perform the connection/authentication protocol is significant, and the power consumed by the Wi-Fi transmitter section is more than 350mA. Later in the article I’ll explain my earlier method of doing this, and why I decided to use another method.Īnother issue that ties in with this is the power consumption of the ESP8266 or ESP32 when the units are battery operated-which is the case with the water leak detectors. Although the leak detector included a piezo speaker that provides a loud beep, there is no guarantee that you are going to be at home if a pipe springs a leak. When I built the original units, my goal was to have them send me both an email and SMS text message if a leak was detected. The other issue I ran into concerned the cloud service I was using to handle three water leak detectors I had built. However, if home monitoring/control devices lose their wireless connection, it may not be evident immediately that rebooting is necessary.

I’m sure that it’s not a problem with my homebrew devices, since it’s just as likely to occur on my iPad or the TV set-top box itself. This requires that the modem/router/WAP be unplugged or rebooted. Although I am getting 500Mbps speeds consistently, for some unknown reason, I occasionally find that one or more devices in the house lose their connection (IP lease) to the modem/router/WAP. Therefore, I must use the integrated fiber optic modem/router/Wi-Fi Access Point (WAP) unit supplied by my service provider. I am lucky enough to have Internet service delivered via fiber optic cable right into my house.
This worked OK, but there were some challenges. In other cases, I used various cloud services to collect data. Sometimes I implemented web-server firmware in the project. In each case, the project connected via Wi-Fi to my home router/wireless access point. I’ve built several ESP8266/32 home monitoring and control projects over the past few years. I have also found the ESP32 to be a cost-effective microcontroller (MCU) in some projects that didn’t even require wireless connectivity.

While the ESP8266 had limited GPIO, that was taken care of when the ESP32 came out, and the latter also added Bluetooth LE capability. Ever since Espressif introduced the ESP8266, I’ve been doing Wi-Fi based projects with it.
