@Jon I have received the plugs, installed in the network and configured it in NodeRed. It seems that it there is a problem with autohorization. Debug: Error: Unauthorized: check username/password ![](https://community.openenergymonitor.org/uploads/default/original/1X/e691e4662f339be573e63d50eab45b046066ef14.PNG) ![](https://community.openenergymonitor.org/uploads/default/original/1X/6baae5f0178fd912c38507f4970c2a06aa9a940b.PNG) I used the name of the plug as in the app in IOS and the standard password 1234. ---

You’re right! Thanks. Next error unfortunatly: Error: connect EHOSTUNREACH ---

From my brief experience that error usually happens when the SmartPlug is not power up (meaning plugged into a live power outlet). Are you able to control the SmartPlug and see the power readings from the Smart Phone app? ---

> [@Jon](#): > > @bart and @Dave - Assuming you have Node-RED (and its dependencies) all set-up and runn I still had to restart and the problem solved. Now all the smartplugs are working. ---

The voltage calculations turns into strange low values due to the powerfactor. The code should be P = U \* I \* Powerfactor. “volts:” + (msg.payload.status.nowPower/msg.payload.status.nowCurrent / POWERFACTOR); Where can I find the available definitions? msg.payload.status.nowPF or something? ---

The voltage calculation was me experimenting more than anything else. The available measurements from the Node-RED SmartPlug node are: **state** = msg.payload.status.state **nowPower** = msg.payload.status.nowPower **nowCurrent** = msg.payload.status.nowCurrent **day** = (same pattern as above) **week** **month** **lastToggleTime** ![](https://community.openenergymonitor.org/uploads/default/original/1X/54265703addd40cffc2ad4317c7f4902c65abc26.png) ---

Glyn, were you ever able to regally poll the wemo insight to get usage data? If so, do you have a node red flow you can share? Thanks kindly. Mike. ---

No, gave up on it. Was too unreliable. I returned the unit. ---

Mike - I am guessing you already have the node-red node - [node-red-node-wemo](https://flows.nodered.org/node/node-red-node-wemo). There is an older example available[Belkin Wemo Switch Control](https://flows.nodered.org/flow/1e53e9501a6adb1bbfba) And there is even an emulator available for the Amazon Echo Alexa: [node-red-contrib-wemo-emulator](https://flows.nodered.org/node/node-red-contrib-wemo-emulator) maybe one of those will help… ---

Thanks for everyones input into this, I recently received an EdiMax Plug and quickly got it working with node-red thanks to this post. The only thing i found i was missing was last state i spent a bit of time and came up with the following flows, in addition to the previous requirements you will need node-re-ping [https://www.npmjs.com/package/node-red-node-ping](https://www.npmjs.com/package/node-red-node-ping). welcome to suggestions on improvements i would like to verify the plug is set to the last state and then end the flow how ever i’ll do that tomorrow now. ![](https://community.openenergymonitor.org/uploads/default/original/2X/7/769edb3c7449e608ee10ebbab57f1ad9a4e490e8.PNG) This is the json info

Hi, Based on this thread, I purchased an EdiMax SP-2101W, installed it with the iOS app, upgraded the firmware to v2.08, installed node-red-contrib-smartplug on my EmonPi’s NodeRED (via Hamburger Menu \> Manage Palette). I then created a flow by copying the JSON posted above by Jon (May '16), configured the smartplug-device with the appropriate IP, admin username and password. I also changed the emoncms node to push to node 18 instead of 16. After deploying, all I get is an error in the debug panel: _“Credential type ‘smartplug-device’ is not registered”_ I rebooted the emonPi and logged back into Node-RED, and this time I got notification that smartplug-in and smartplug-out are unrecognised device types… — (later) — I re-read [Outdoor Temperature Data from Weather Underground to Emoncms & MQTT - Blog | OpenEnergyMonitor](https://blog.openenergymonitor.org/2016/02/outdoor-temperature-data-from-weather/) which made me think that maybe I shouldn’t install node-red-contrib-smartplug through the web UI, but through command line I sshed into the emonPi and ran the following: ``` $ rpi-rw $ cd ~/data/node-red $ sudo npm install node-red-contrib-smartplug $ rpi-ro $ node-red-stop $ node-red-start ``` No luck there either, with the following output: ``` 5 Jul 17:19:28 - [info] Node-RED version: v0.15.2 5 Jul 17:19:28 - [info] Node.js version: v0.10.29 5 Jul 17:19:28 - [info] Linux 4.4.26-v7+ arm LE 5 Jul 17:19:30 - [info] Loading palette nodes pi : TTY=unknown ; PWD=/home/pi ; USER=root ; COMMAND=/usr/bin/python -u /usr/lib/node_modules/node-red/nodes/core/hardware/nrgpio.py info pam_unix(sudo:session): session opened for user root by (uid=0) pam_unix(sudo:session): session closed for user root 5 Jul 17:19:43 - [warn] ------------------------------------------------------ 5 Jul 17:19:43 - [warn] [sensehat] Error: Can't find Sense HAT python libraries.
