Hi All,
I posted on how to get third party Gas Sensors hooked up and have created a flow and all works well.
BUT the only way to display was as a tank and this also is acceptable and i would like to change the displayed value from Kl or l to a custom unit such as ppm or just % and there does not seem to be a custom value to change this, however i know some of the experienced node-red users will be able to point me in the right direction.
