I gave up with Ext3 calendar and settled on Ext2

Not completely happy but getting there

This is an early development version of what will be my office display, used as a screensaver when the display isn’t in use
the actual display is a 4k 65" smart display, it is in storage until the office move

The 2 modules I wanted did not exist, so I wrote them both

UK Grid Status https://github.com/KayosPi/MMM-UKGridStatus
Does not require API’s and shows either realtime or snapshots of the UK grid

Solax PV https://github.com/KayosPi/MMM-SolaxPV
Displays information from a Solax PV inverter, customisable to show whatever you want to see. Needs an API and a serial number linked to that API

Now it works, I will make it look nice

I have created a module to read the Solax PV API when given a valid key and inverter serial number

It has a text mode and I am working on a graphics mode

I have also created a version that aggregates data from multiple inverters, using the same API, however unless you are an installer, O&M or have lots of inverters, this will not be any use

I am getting to grips with Github and will upload it when I have that sorted
