New Product - Color LED v2 with temperature sensor

The OpenEVSE team has been focused on safety since the project began in 2011. Recently a new safety feature was added to the OpenEVSE firmware to monitor the internal temperature of the charging station. If things get too hot... charging current is reduced or stopped.

 

Version 2 of the Color LED adds a MCP9808 high precision temperature sensor, providing OEMs and DIY builders a low cost solution to status indication while adding the necessary sensor to provide temperature monitoring and throttling.

Likely not. All LCDs with the DS3231 RTC chip report temperature.

I bought OpenEVSE Color LCD v2 + Temperature

I already had a 2015 Colour LCD + RTC


My WiFi unit seems to get temperature data. Do I need to install the LCD V2?

Is this an add on temp sensor or a replacement for the LCD display

The color RGB LCDs with the clock already have a built in sensor. This can be added to stations without a display or stations that do not have the RTC clock chip.  

The WiFi/OpenCMS reports an IR temp TMP007 on Temp3, is that actually supported? It always reports 23C on mine, wondering if it is not present or is broken. Also has an MCP9808 for Temp2 but always reports NaN. The DS3231 on Temp1 is fine.

Yes, the LED is the same hardware as the LCD, RGB LEDs of both connect to the same IO pins so they are plug compatible.

I have the exact same question as Chris Meier.

I have an Advanced Series Kit with LCD display. Is it possible to configure the OpenEVSE with the LCD for a certain installation conditions and then replace it to the Color LED v2 board before installing the wallbox for operation?

The idea behind the question before is that the installed wallbox should not have any kind of programming or configuration change in the charging point. The push button should be eliminated too.

In this way the access to all charging data and EVSE configuration should be done by wifi.

Anyone can confirm if such configuration could work?   

The point behind the question before is that I want to install the EVSE without LCD display and the push button neither. In this way no one could make any changes to its configuration. If any configuration change would be necessary in the future so it should be done through the wi-fi.

Could any one confirm if such operation mode could work fine?
