very advanced flashing utilities you got there :muscle:

Iā€™m always going the low-tech/low-effort way and just ask for one or two helping hands :open_hands:

For the sinilink device I actually just used dupont wires and holding them while flashing (3-4 hands were included in that action). :vulcan_salute:

Because ā€œfreeingā€ esp based device hardly takes 60 seconds (usually much less) I virtually never solder wires or pins but just do it always ā€œfreelyā€. Even shorting wires or loosing grip while flashing never killed any of my devices. Worst case is to initiate the flashing process once again - bricking espā€™s is simply not possible afaik. :ok_hand:

@lmatter I was hoping the same thing. Did you ever find and interface to use to type in wi-fi creds? I canā€™t get mine to fully connect

I did - check out my comment a bit after that one. I used my Windows laptop to create a ā€œhotspotā€ that only had 2.4GHz so I was able to get them registered with eWeLink. SONOFF Micro - 5V Wireless USB Smart Adaptor - #12 by lmatter

I wanted to keep them on the same lan so HA could use local API so didnā€™t want to go this route. Based on another thread I tried a tablet I had and my micros connected right away. Two different android phones didnā€™t work, but an android tablet worked perfect. Such a waste of time trying to get these things to connect!!!

Any chance you could share your yaml for these?

I think I got this from somewhere else, so I canā€™t take credit for this

Looks like it came from here, but maybe has gotten updated since I first used it

Many thanks!

I wrote a short SINILINK guide a while ago.

Was anyone able to get this to pass through data / does the sinilnk pass through or control the data lines?

To my knowledge the sinilink does pass data. Check the video on those devices by the guy with the Swiss accent.
