Look inside the MMM-network-signal.js and add a colour code there ( RGB format # xxxxxx).
Try at line 58.

Hello,

I am using the netatmo weather module but I have also got a homecoach module and I know that the weather module will not work to display data from it but I do not have the knowledge to code or modify an existing netatmo weather module.
Anyone else looked into this and maybe found a module that might work ?

Thanks.
