Many thanks to Gary, slipx06 and all the other contributors to this topic of integrating the Sunsynk inverter into Home Assistant.
By following the instructions and by changing various nodes where errors have occurred, according to threads in this forum, I now have the values from my inverter coming through to Node-red that are visible in the Context Data tab and that match the values on my Sunsynk app. However, none of these values appear in Home Assistant sensors as they are all unavailable. I still have some issues to resolve and being very new to Home Assistant and Node-red I'm not sure how to proceed.
1. On Node: Run Through Plant Inv List, I get this error reported in the debug window
"Gateway is bad. Not configured for <= 60s cycle rate. Updates Disabled"
How do I overcome this? Is there a setting in a node or nodes that I can change to reduce the updates to say every five minutes just to get the updates going?
2. On Node: Update Sensor, all of the API calls appear to be unauthorised. I get this list of errors reported in the debug window.

I'd be very grateful if someone could point me in the right direction with this please. If there are there any logs that would be useful to solve the problem please let me know.
