I have setup a mysensors network in my house and garden and its working rather well now. Among others, I have several DHP sensors sending temperature and humidity and I can display them quite well on the dashboard on grouped graphes.
As I want to compare the absolute humidity in different areas, I created in the local node Arduino scripts a function, that calculates an estimation of absolut humidity, which is then send as Custom sensor and Variable 1 to the controller. Mycontroller does receive them and I can see the values individually on the different ressource pages and also as value on the dashboard.
But I can't get this value being displayed in a graph (like temperature and relative humidity). When I generate a new graph, the sensors just do not show as posibility to select for a grouped sensor graph.
Any hint where I can find a solution?
I thank you in advance !
