I have been looking on the net for a while now and have not seen anyone done this in simple way yet ( my coding skills at current is almost none exsisting ).

I have Arduino NodeMCU's gathering temperatures info from my house. I use Blynk (at current, but adding also now direct path to thingSpeak also) to gather the data on App , but what I really would like to is create a map of the house and have as overlay last channel information on specific locations.

I have read sample (tutorials) on here like creating a overlay map ( and how t get data from channels but that where my skills hit a wall.

Has anyone create anything like that and how would one start to work on it ?

I also want to make such a 2D overlay based on real time data. I think it would be even better if it had 3D projections and animation of time-lapse data. I'm working on it slowly.

What else would you like to do that is not demonstrated in the heatmap demo? Do you have your temperature data posted to thingspeak channels?
I think the next step after that is to generate the base map to put the heatmap overlay onto. If you don't have an online file already, you can generate on in MATLAB.
For example, see

rectangle('Position',[1 2 5 6])
axis([0 10 0 10])

The next step it to aggregate the data from thingspeak, and then generate the overlay. Let us know if you get stuck.
