Auduino Nano and Ethernet Gateway?

MatrixIII last edited by

For the gateway I was powering both the ENC28J60 and the Radio with Auduino Nano 3.3v onboard power. What I noticed was that the Ethernet shield (ENC28J60) was powering but but not communicating with "check wires" message on the console. Putting a multi-meter on the Ethernet shield and the radio - they were only receiving about 1.5v - 2.0v. I also had a UNO and used that with the same exact setup - powering both with UNO's 3.3v onboard which fixed the issue and both Ethernet shield and the radio were now receiving around 3.3v and the gateway powered up and I was able to connect it to Vera.

My question is that - is this a known issue with Nano? It would make sense that the Ethernet shield be powered separately from a 3.3v supply but I didn't see any notes on the Ethernet Controller page so wanted to check. I am assuming that UNO was able to provide more stable power to these devices.

Hi @edoardoo I actually stumbled on your post a couple of weeks ago! Great writeup! We certainly need contributors. We need help with everything from the visualisation of sensordata in the frontend (considering using d3.js) to mqtt/node.js backend for receiving and processing sensor data. Please contact me or Johan for further discussions.

@mfalkvidd said in Best PC platform for running Esxi/Docker at home?: @NeverDie ...You can also use the command line tool fstrim to manually discard unused data. Looking into this, I think checking the "Discard" box on the "Hard Disk" tab of the "Create a Virtual Machine" dialog box inside ProxMox may automatically accomplish the same thing. Also the ProxMox dataset that the VM is saved on needs to be set to thin-client. So, those two things plus the ssd emulation that you mentioned, and of course automatic file compression like lz4 needs to be enabled. So, in total, four things need to be set correctly for it to work optimally. Originally I was concerned that because, if using ZFS as the file system, ProxMox only allows storing a VM as a pre-allocated "raw" file (rather than as a qcow2 file as ProxMox would if ProMox were using a linux ext16 file system instead of ZFS) that the file would take up enormous space even if the raw file (i.e. the VM's virtual disk) is mostly empty. So, I did the experiment, and it turns out that is true if the ProxMox dataset isn't configured as "thin-client" or if automatic file compression isn't turned on, but fortunately the true size of the raw file does indeed shrink down if those two conditions are enabled. So, having proved that to myself, I'll pass on the tip: I now create a VM's disk to be as large as I can imagine it would ever need to grow, and then I let the thin-client mechanism maintain the true size of the virtual disk to be only as large as what is actually necessary. This way I don't have to worry that I created too small a VM disk, or that the VM will later outgrow the disk size that was originally allocated for it.

@David-Dawson great idea for that translation from homie to mysensors and back. but I think it would be a better approach, if mysensors would have the ability to "speak" homie-convention in MQTT optionally (e.g. #MY_GATEWAY_MQTT_HOMIE) that would eliminate the need of tweaking on an extra binding and let mysensors talk an IOT-standard

Hi dzairo, Just wondering if you still monitor this thread. If so would love to know how to install the ComPort component so I can modify and use your terminal code. For some reason I don't have any luck with adding it to the IDE. thanks, Andy.

Naturally, using Tasmota instead of ESPHome should work equally well.

I have a similar project: For my fathers boat, I want to use a Nextion as a central informations display. I will use a asr6501 as self containing gateway/controller, so maybe we can exchange experiences.
