Woo Hoo! Commenting out those two lines ( `arm_freq=1200` and `gpu_mem=16` ) & rebooting the Pi Zero, and it appears in the router’s CP.

After typing in the LAN IP I get the “Welcome to your emonPi” page. This is presumably what @lgheorghe was seeing on [Getting setup wizard page instead of login](https://community.openenergymonitor.org/t/getting-setup-wizard-page-instead-of-login/15205) . I clicked on the wifi option, and then after reconnecting to emonpi.local I get in to a bit of a loop - searching for networks (again).

Not sure how important this is - possibly related to the above - but above the Welcome page there is a warning message

` **Warning** : file_get_contents(/etc/wpa_supplicant/wpa_supplicant.conf): failed to open stream: Permission denied in **/var/www/emoncms/Modules/setup/setup_model.php** on line **24** `

The Pi is powered through my emonTx, with the wires connected as per @pb66 's second schematic:  
4: 5v \> 5v  
6: Gnd \> gnd  
8: tx \> tx  
10: rx \> rx  
12: p12 \> rts

I am able to ssh in to the Pi, but my linux skills are so limited that I although I am able to use some _very_ basic commands (`cd` and `ls` etc), am not yet able to poke around (or change) anything. (EDITORS Note: Good job probably 😀 )

So, progress (thank you all), but still not quite there yet.
