Wemos in a Pelonis
This post will cover the use of the ESP8266 clone form factor of the more popular Wemos D1 Mini. This clone development module has the same pinout and interfaces as the Wemos D1 Mini. The Arduino IDE was set to use the NodeMCU 1.0 ESP12E Module for the code below, although the LOLIN(WEMOS) D1 mini (clone) was avaliable. This board selection didn’t present any issues when loading the firmware.
The board is inexpensive, a 10 pack can run around $25. It doesn’t have all of the GPIOs of a full ESP32 dev board, or some of the peripherals of the ESP32-Cam board. But the low cost and targeted use make it a viable option.
This post is intended as a demonstration only, please do not repeat these steps on any heating equipment you have at your disposal. The work done here is intended to provide a foundation for further work unrelated to space heating. I can’t stress enough the dangers of mishandling mains appliances, you stand a serious risk to you or someone you know if you carelessly attempt this, so don’t. You have been warned.
In this post, the module was installed in a space heater. It monitors the space heater control buttons. The module can also mimic input to the space heater to operate it. Based on the space heater operating state, the module monitors the energy use of the space heater. The module interfaces with a wireless network and communicates with a MQTT broker. Node-Red is used to interface with the module through the MQTT broker. Node-Red has flows that track the module readings and presents an interface for user control.
Here is the pinout of the module, it should be pointed out that the silk screening on the module is misleading. This can present issues for developers that aren’t aware of the GPIO to digital and analog pin numbering scheme.
Since the space heater inputs operated at a 5 volt logic, a level shifter was placed between the module and space heater controller. Since the space heater provided an adequate 5 volt supply, this was fed to the module. Here is a pinout of the connections.
The green line connects the module D1 pin (GPIO 5) to the space heater on/off button. The yellow line connects the module D6 pin (GPIO 12) to the space heater mode button. Again, these traverse a level shifter to keep the module GPIO pins at 3.3 volts and the space heater pins at 5 volts. Here is a photo of the components installed in the space heater control panel.
After reassembly, the space heater appears the same as it had before the modification.
Here is the Arduino code that was programmed on the module.

ESP.getVcc() may be used to measure supply voltage. ESP needs to reconfigure the ADC at
startup in order for this feature to be available. Add the following line to the top of
your sketch to use getVcc:
ADC_MODE(ADC_VCC);
TOUT pin has to be disconnected in this mode.
Note that by default ADC is configured to read from TOUT pin using analogRead(A0), and
ESP.getVCC() is not available.

Wattage Usage Calculations
Based on Amp meter readings
High Mode = 12.5 Amps with 120 Volt AC Source
Low Mode = 7 Amps with 120 Volt AC Source
MQTT Status message are sent every 5 seconds
To cacluate watt hours used the mode amp value is multiplied by the source voltage
ie. 7 * 120 = 840 Watts
The result is then devided by the amount of time that has passed since the last reading
ie. 840 / (60 * 12) = 1.1667 Watts used in 5 seconds
The Watts used in 5 seconds becomes the factor to add to the variable WattsUsed
High Mode = 2.08
Low Mode = 1.17

The Node-Red flows are similar to earlier posting on this blog. However, the energy usage flows use a math function to provide a daily average of watt hours used.
Here are the details for the watt usage flows.
