![]() Remote monitoring, scalability, the versatility to use with any battery type, and the ability to monitor separate battery systems simultaneously (UPS, switchgear, generator) are available options with these next-gen monitoring systems. Overall preventive maintenance costs are reduced as well. This reduces the wasteful precautionary replacement practice of installing new batteries before they are needed. Monitoring your batteries helps eliminate costly unplanned outages, extends battery life by allowing a view into the health of the battery. Know the instant a backup battery shows signs of failure. ![]() Power Solutions offers a range of monitoring systems for UPS batteries by Cellwatch, BTech, and Alber. Predict performance and make informed, data-driven decisions to better manage your most critical and costly assets – your standby power batteries.

After I saved, I restarted home assistant for it to take effect. The last step was closing the fuse box and the car hood.īack in Home Assistant, I opened the configuration file and added a new MQTT sensor. I then did some trial and error until my reading was 1273 as the analog reading. I did this by connecting a multimeter to the battery and read the current voltage (in my case it was 12.73 volts). I then proceeded with calibrating the range of the analog input. Next, I located the nearest connection to the battery positive rail and connected my positive power input to it. Since the entire car chase is ground, I found the nearest screw and connected my ground to it. I found the fuse box to be a safe and secure place to install my device.I first wrapped the device in heat resistant tape to cover any exported pin to withstand the engine heat. I attached a long wire to the power input terminals to be able to connect them to the car battery.Īt the car, I opened the hood and located the fuse box. I then resumed with a typical Tasmota configuration. Make sure you select the sensor.bin version for the Analog input functionality. I then connected the D1 mini to my laptop and load the software. I did this by soldering a 1MΩ resistor to a 220KΩ resistor as shown here. To do that we can add another 1.22MΩ in series to get the total 1.44MΩ. To increase the 3.3v to 16v needed for the car battery, we need to increase R1 to 1.44MΩ. This the voltage within the 0-1 Volt that the ADC can tolerate. The D1 mini can measure external voltage up to 3.3v by using a voltage divider using R1=220KΩ & R2=100KΩ. First, I started by removing the power plug and installed the smaller connector to make the hardware more compact. You will need a wemos d1 mini, a power shield and some resistors. ![]() I will show you how I assembled the hardware, loaded the software and installed the monitor in my car. Having the ability to monitor your car battery can prevent some unpleasant surprises. Please check the video description for links for the D1 Mini Power shield I used. ![]()
