Thanks for that tip and glad to hear that you found a work around fix to the problem.
I'll keep that in mind if I start seeing that apparently one time lock up event I experienced a few weeks ago on a more regular basis.
Just to be clear, by 'penultimate firmware update' you're referring to the 1.3.23 released 2018-09-27 ? I'm currently on firmware 1.3.26 EN dated 2019-08-07(
see below). Looking at the creation dates on the download folders, I seem to have applied that update less than 4 weeks after its release (2019-06-17 according to the revision history pdf).
I note I also have folders for the three preceding firmware updates all dated 2019-02-19. That just means I'd downloaded those as a precautionary measure in case an issue like yours were to arise. After my experience with uBlox's shit attitude to archiving old versions of u-centre, I didn't want to take the risk of the earlier firmware versions suddenly vanishing from all existence.
I doubt I'm not the only one who grabs what they can whilst it's still there for the taking, especially when it comes to earlier, perhaps less demanding of the hardware, firmware versions that could prove to be a 'Life Saver' should a new bug arise or an ageing effect make itself felt with the latest, perhaps more demanding firmware.
Although I've been using the SDS2104X+ (long since updated to the 2504 spec) for the past 11 months, I've no intention of selling my trusty 1202X-E, it's just too usefully portable and economic of power consumption (2/22W versus the 4/54W of the 2104), hence my using it for testing the fridge startup current surge demand (plus it starts up in just 16 seconds versus the 46 seconds it takes for the 2104 get up off its fat arse and actually do something more useful than displaying its "Blinken Lights")
).
