Espurna: Support Blitzwolf BW-SHP2 v2.3

Created on 15 Nov 2018 · 5Comments · Source: xoseperez/espurna

I bought a Blitzwolf SHP2 and got a new Hardware revosion which looks exactly like the on described here: https://github.com/arendst/Sonoff-Tasmota/wiki/Gosund-SP1#new-hardware-revision

The espurna-1.13.3-blitzwolf-bwshp2.bin files boots and WiFi works, but all sensor values are either missing or wrong.

It works with Tasmota, but I would love to use espurna.

There are the PIN/config settings they are using: https://github.com/arendst/Sonoff-Tasmota/issues/4297#issuecomment-436804860

I can confirm above settings are correct. (And created pull request #1351 for this)
