Got it working! I think I’ll just avoid dot notation from now on…

Repo is linked below. If anyone’s looking to use this, OpenWeatherMap’s One Call API asks for latitude and longitude instead of a location or location ID. But in return, you can get not only current and daily (max 7 days) forecasts, but also hourly forecasts (max 48 hours).

All original functionality of the module should remain intact.

Sample Module Configurations:

{
	module: "weather",
	position: "bottom_left",
	header: "Current Forecast",
	config: {
		weatherProvider: "openweathermap",
		weatherEndpoint: "/onecall",
		type: "wDataCurrent",
		apiKey: "OPENWEATHERMAPAPIKEY", // your OpenWeatherMap API key
		initialLoadDelay: 0,
		lat: 40.7128, // your latitude
		lon: -74.0060, // your longitude
	}
},
{
	module: "weather",
	position: "bottom_center",
	header: "Hourly Forecast",
	config: {
		weatherProvider: "openweathermap",
		weatherEndpoint: "/onecall",
		type: "wDataHourly",
		apiKey: "OPENWEATHERMAPAPIKEY", // your OpenWeatherMap API key
		initialLoadDelay: 2500,
		lat: 40.7128, // your latitude
		lon: -74.0060, // your longitude
		maxEntries: 32, // max 48, set by OWM One Call API
		showPrecipitationAmount: true
	}
},
{
	module: "weather",
	position: "bottom_right",
	header: "Daily Forecast",
	config: {
		weatherProvider: "openweathermap",
		weatherEndpoint: "/onecall",
		type: "wDataDaily",
		apiKey: "OPENWEATHERMAPAPIKEY", // your OpenWeatherMap API key
		initialLoadDelay: 5000,
		lat: 40.7128, // your latitude
		lon: -74.0060, // your longitude
		maxEntries: 7, // max 7, set by OWM One Call API
		colored: true,
		showPrecipitationAmount: true
	}
}

Not making a pull request yet since I don’t know how the default Weather module is meant to be designed.

If you’re still looking @mrlowndes, I recently got an hourly weather forecast modification of the default weather module working. It uses the OpenWeatherMap One Call API which allows for 1 hour interval forecasts for the next 48 hours.

Link to repo branch.

Screenshot and example module config available in the forum post I made in Development while trying to debug it.
