HVAC & Far Infrared heating
Main Dashboard
I cooked up a few custom drivers and apps to let me have some event driven, more informative dashboard elements.
Far Infrared Dashboard
Note: I ams using a text widget on the Hubitat dashboard to embed a node red page.
Seems to work well.

I know it won't work remotely but I have a specific remote dashboard for phone use with only Hubitat widgets on it.
We use Node-Red running in Docker on an eWeLink CUBE for most of the cyclical action freeing up the C7 so its more responsive. The node-red instance is rock solid.
That said the Huitat is solid and reliable now and controls the whole house with a couple of custom apps and some rules only.
It's pretty simple; eWeLink CUBE works out the duty cycles for the Fare Infrared Panels and controls some Tuya smart plugs via Habitat.
The same plugs are also power monitors which is used by the solar optimisation flow and the energy monitoring logging flows.
I made the wee dash in the text box above with Claude AI code generator in five minutes. Seems my coding career is well and truly over
It allows me to pick days from the logging database. the eWeLink CUDE handle database access via HTTP and the Hubitat MakerAPI as appropriate.

The Regime
The devices are exposed via MakerAPI to Node-Red and events are handled in real-time there. This unloads the C7 a lot and ist way more responsive than it was when it was calculating the FIR panel duty cycles in an App
The flow below uses a two second tick so 100% duty cycle is 120 seconds. Seems to be a good compromise keeping the relays in the Tuya plugs switch too fast, while not letting occupants feel cold when the panel is not powered on its off period.
Ventilation
The ventilation is also managed in conjunction with the HVAC and far infrared panels.
Note: There is a home brew heat exchanger on the vent which fits in a partly open window.
