Domoticz

Hi,
I have an array of Shelly sensors, Heatmiser UFH and Honeywell Evohome feeding into Domoticz.

I would like to create a control panel that indicates by way of red/orange/green monitor lights which sensor is currently calling the boiler for heat.
All of the sensors have set points and current temperatures so I am presuming I should be able to create a script for each monitor light by comparing the set point to the current temperature and assigning a colour accordingly. Ideally I would like to be able to record the status of these monitor lights by way of a historical graph so I can compare boiler load against demand.

Main reason for doing this is diagnostic rather than automation, so the monitor lights are very much for historical tracking over being used to action anything.

I have no idea if the above can be completed from within Domoticz or how I would go about creating, hence this post hoping for a pointer or two.
I am very new to Domoticz but a relatively quick learner but struggling with the semantics to track down what i need.

First, giving colors to sensors is not a standard function in Domoticz.

Is the evohome itself not giving the information what sensor/room is triggering the heat demand? I do not have an evohome so fully unaware. There is a special evohome subsection in the forum, perhaps search there. viewforum.php?f=80

You can make custom icons red/green for a On/Off switch.
If you need 3 levels, you can use a selector switch to have 3 states red, yellow, green, but unfortunally you can't have 3 colors.

It will be nice if both the selector switch and dimmer widget can assume different colors set by plugin and script in the future!
