I recently bought two Sonoff POW R2 devices from Amazon to use with MQTT to measure power consumption. I’ve got them working nicely with Tasmota v 8.1.0 and would like to buy a few more from AliExpress. However, I’ve noticed a small difference in the writing on the case of my Sonoffs and the pictures of the Sonoffs on AliExpress. My devices have “Sonoff POW R2” printed on them, the pictures on AliExpress have “Sonoff POW Rev2” printed on them.
Is there any actual difference in the hardware? It seems strange that the wording is different. Is the Rev2 a revision to the original Sonoff POW and the R2 is a new product? I can’t seem to find any details using Google.
