ITEAD Recall

Just in case you haven’t seen it already, ITEAD Studio is recalling some of their Sonoff devices.Sonoff damaged by heat

The recall covers Sonoff TH16 and Sonoff POW units, manufactured during December 2016 and January 2017, which were produced without the correct amount of tinning on the AC power traces required to carry the maximum specified current.

There doesn’t seem to be any easy way to identify affected units though and the recall Sonoff PCB damagenotice seems to infer that only Sonoffs with existing, visible damage will be exchanged.

It’s worth noting that this issue only affects units which are being used with high current loads, so it’s unlikely that you’re going to have problems if you’re only using the modules to switch on your porch lights at dusk.  However, as these units were sold specifically for their higher current handling ability over the original Sonoffs, it is probable that there are many use cases out there which will be affected by this issue.  If you’ve purchased a TH16 or POW unit recently and you’re using it with a load which draws quite a lot of current (any sort of heater, for instance), you should probably stop using it until you can verify with ITEAD Studio whether it is amongst the affected units or not.

ITEAD are asking that people who believe they have an affected TH16 or POW to open a support ticket on their site at:-  https://www.itead.cc/contact-us
