@1024Bytes@masto.ai Ziggo. I have been on the helpdesk for an hour or two including a video scan of the situation. The guy tried to help but I suspect he can't look into the system deep enough. Tomorrow a mechanic will come and will see I have made no mistakes and then he will make a phone call and it'll be fixed. I discovered that my 'intelligent" heating system also works without internet. Positive. All that crawling around the flood has made my back go all bad.
