Hi Neil,
Now running Indigo on the new mac. So IOS 12.3 (Monterey) and Indigo 2022.1.2.
As anticipated the migration from python 2.7 to 3.1 is proving a little painful, so only about 1/3 of the functionality currently working - but over the biggest hump. Also still having problems with a number of plugins which are supposedly compatible, despite having started Rosetta II.
However your Octopus plugin now appears to be working fine! Thanks for your support.
Its my son (who has an Indigo system managed by me) who currently has the solar panels and Eddi, so will check with him and get back to you, but I don't see any problems in providing you with an API key or whatever login details are needed to develop the plugin.
I am also looking at solar panels and, having seen what the Eddi provides in a system, I would specify one of these as well, and seek to integrate the use of the data into Indigo. Essentially, the cost per unit of elecgtricity you import is so much higher than the cost per unit you export, even with Agile Octopus, that maximising self-consumption is key to making solar panels cost effective, meaning that measuring and controlling your energy genertion and usage is key.
The Eddi is a clever standalone device since it varies energy use by varying the AC voltage applied to a fixed resistive load (e.g. water heater) - I think their advertising undersells it but the Eddi manual gives good detail - but it also acquires much of the input data you need in Indigo, and the rest can come from Z-wave devices on individual electrical loads.
So I would definitely encourage, and support as much as I can, the development of a suitable plugin for Eddie/Zappi.
