This subflow uses the http request node to fetch solar forecasts for geographical positions, using the API from https://forecast.solar/. Please check their website and consider getting a paid account.
Do note that, on a free account, you are limited in the number of requests to do. Also note that the data only gets updated once every 15 minutes, so there is no reason to query more often. There is rate limiting built in the subflow not to perform requests more than once every 15 minutes.

This subflow tries to make it easier to use modbus tcp to query and modify Victron Energy equipment via modbus tcp. By default the subflow will try to connect to 127.0.0.1.
It requires the following node to be added to the palette before installing the subflow:
Installing the subflow is a matter of copying the flow below and pasting it via the Import menu. (ctrl-i)
This subflow uses the energy zero API for retrieving the hourly energy prices from the API of https://www.energyzero.nl/ for either today or the next day. These are the prices as they are used by the Dutch energy providers ANWB energie, Energie van Ons and others.
In order not to load the API too heavy a rate limiter of 1 query per 15 minutes has been added to the subflow.
Do note that tomorrows prices can be queried after 15:00, so there is a delay built in the node that handles that.
This subflow node is for retrieving the weather information from an Alecto weatherstation. It does this by listening for post requests.
In order to get this working, you need to add a customized service to the weather station. This can be done in the WS View app, under device list. Under Customized add:
