Thanks, have installed that, and will leave it running overnight.
I've had a weird thing in the past - can't remember the exact details - whereby the line PN thought they were monitoring was not mine! So if it turns out PN are logging "disconnects" that are not matched by my own monitoring, that in itself would tell us something.
I have left the graphs to autoscale - I don't know how long it will take them to adjust, because at the moment, my speeds are so low that a scale of 0 to 8000 Kbps is inappropriate, and my graph is indistinguishable from the zero line (though clearly I'm still connected). I'm assuming that once it's collected enough samples, autoscale will compensate for this.
Have also noted your words of caution about inadvertently triggering a new contract. I'll be as specific as I can that I'm only wanting to claim a previously unclaimed router from the existing contract. But coincidentally, it has less than a month left to run, so if it did somehow go wrong, it's not going to make a huge amount of difference, that I can see. It has to start a new one soon in any case.
Edit: Alas, it doesn't work. It's not just a scaling problem; it's consistently showing my download speed as "zero", regardles how I set the axes. Basically, my PN-supplied router is not supported. It's a Thomson Speedtouch TG585 v8. Only Vs. 6 & 7 are expressly listed as supported by Routerstats-Lite, BUT I'd hoped they might be similar enough it would accept it anyway. At first glance, all seemed OK, because it doesn't come up with an error to say it can't read the speed data. The help files suggest it should, if that were the problem, to enable you to distinguish between a genuine zero reading, and a null or failed return.
But, as abysmal as my speeds are, I'm sure they're not zero. It doesn't look as if it's ever going to report anything but zero.
