Can I use Telnet or SSH to communicate to the Open EVSE via the WiFi's IP address? I have Firmware 3.10.3

Chris H, In your post above with graph, how did you get the Main Power data stream?

The Wifi module currently only supports http, If a library is created I will add SSH.


Main power is coming from the Rainforest Eagle Gateway and a simple python script. I posted about it in the OpenEVSE Blog. 

I'm not finding an installation guide for the WiFi module, or any information on how to configure it for my SSID and password.

The guide for Wifi is here:

I got the wifi kit working from the guide. My EVSE was assembled by Bret at BSA in Las Vegus Nevada in late 2015. I had already done one F/W update. It's BSA modified F/W (ie non stock) but the WiFi module worked with it fine. I haven't tried sending commands to the EVSE but the monitoring works fine. One problem, led me to remount the module lower down in the EVSE case and only use half of the mounting tape provided. I will try to post an interior view photo of the first mounting spot. Final location was on the oposite wall and lower down. I has worked like a "bought-one" for 4 weeks.

The Wifi board sends current in milliamps. So to convert to Amps the feed multiplier should be .001.


If you wish to see in Kw the feed multiplier would be .001 (to convert milliamps to Amps) and then multiplied by voltage. If our voltage is 233 then then .001 x 233 would be .00233 

Chris, I looked at the Huzzah firmware, and it looks like you have a new stable version with enhanced tabbed web interface. Is it considered stable and production ready? I didn't see any official announcements.

 

No, the new firmware with tabbed interface is still in development. I fixed Github, it looks like I mistakenly pushed an update to the wrong branch.
