> Whist I havent used that version (TTIG & TTKGW yes, but original TTOG no), I therefore have no direct knowledge of typical real world consumption, however, IIRC this uses POE for delivery rather than a seperate power input. From memory this is spec’ed up to 55V @ 0.6A - though in reality likely much lower as this will be for peak?! If you care to share full details then the collective Forum brain might review and spot errors or ommisions and assist. FWIW I had one deployement years ago where …

No direct hands on experience with this version. A few thoughts though:-

When testing inside did you use the original PoE adapter or a replacement? 40+ years experience suggestes 'assume nothing"! 😄

IIRC the TTOG was supplied with a Microchip (was MicroSemi) PD-9001GR 802.3at external adaptor (backwards compatible with 802.3af). This I have seen used elsewhere. A client used 4 on a small deployment and after ~12mo (just after warranty ended!) found one had a soft failure. When checking device was ok on light load but drooped on higher load. Couldnt be certain but he noticed spec limits external (ambient/case) temp at higher loads, but was more relaxed at lighter loads. The one that failed had been mounted in an orangery/conservatory/greenhouse like structure and in summer got real chuffing hot! (failed late summer/fall period). Perhaps check your OG unit with alternate feed? Think direct replacements are ~£40-50 + VAT online.

Another possibility is a close proximity lightning strike (not direct hit of course!) inducing a soft fail, that on power cycling turned hard? That may impact either end (in GW or on PoE adaptor) - was that a possibility?

Unit is actually a Browan OEM design/build so suggest perhaps try their tech support for assist - may get schematic for details GW fault tracing or even looking for alternate power injection points? I would be with Nick on the Caps as likely, followed by protection diode(s) or inductors…
