If the access points are purchased directly from Datto, then (in addition to a one-time purchase) you are also bound to monthly costs per device.

However, open-mesh.nl, as an official open-mesh distributor, has bought a very large stock that falls under the "old" scheme, where you get a cloudtrax license for free without monthly costs. 

A new portal has been created by the former developers of Open-Mesh / Cloudtrax. New hardware has also been developed for this portal, which remains available as usual. Existing Open Mesh access points can also be used in the new portal.

First you need to install “winpcap” on the PC you use for flashing.

Click here for winpcap.
Then download the program below in a folder, for example in “c:\openmesh”.
Click here for v6.4.15: (stable release).
Click here for v6.5.3 (beta release).
Click here for v6.1.5 (for OM2PV1: latest 6.1 version).

Connect the access point to the network via a UTP cable.
Turn off the access point (no power via adapter or no POE).
Open a dos-box (command prompt) and enter the directory where the tool “open-mesh-flash-ng.exe” is located. eg (“cd openmesh”).
Type “open-mesh-flash-ng.exe 1” on the command line (the number can be different with several network cards in the PC, this number is visible by starting exe without a number).
Power up the openmesh access point.
After a short while the tool will recognize the access point and start flashing.
Wait until the program indicates it is safe for you to remove the unit.
Quit the exe / close the dos box.
Turn off the power of the access point and then turn it back on.

Flashing is easiest on Windows, but it is also possible to flash via Linux or a MAC.

The openmesh units communicate with each other for roaming via VLANs. With simple (unmanaged) switches, this usually goes transparently through the switch. With managed switches it should be borne in mind that certain VLANs are open on the relevant port of the managed switch.
The required VLAN numbers depend on the firmware version.

For optimal operation, all openmesh units should preferably be wired. Where it is not possible to connect a unit wired, an openmesh unit can also connect wirelessly to another openmesh access point via the mesh network. At that moment it will work as a kind of repeater.
By default, all OpenMesh access points of a CloudTrax network are on the same channel number. This allows the access points to receive each other's messages. This is used by the mesh network.
However, when the mesh functionality is not required, it is best to set the individual units to a separate WiFi channel number. The advantage of this is that the access points can send and receive completely independently of each other (provided of course no other WiFi access points are active on this set channel number).
Roaming will continue to work in this configuration as well.
The channel number can be entered at “General” | “Add/Edit nodes” can be adjusted. Click on an access point and select a WiFi channel at “Channel override”.
It is also possible to give the same channel number only the access points that need to be able to see each other wirelessly via the mesh network. The other access points can then be set to a separate channel number.

From the 5xx firmware there is also an option to set the channel number setting to “Auto”. In that case, the access point itself will determine the best channel number for the various access points. The system chooses the 2.4GHz channels between channels 1, 6 and 11.

The LEDs on the OM series access points indicate what the device is currently doing. This page contains an overview of the different colors and their meanings.
The OM series has four lights: Power, Ethernet (2) and WiFi.

The Power LED:
• Flashes blue when the device is starting up.
• Stays solid blue after boot.

Ethernet LEDs:
• Stays solid blue when a cable is connected.

WiFi LED:
On gateways, the multi-color WiFi LED has the following statuses:
• No color until DHCP address received.
• Red color if no internet connection yet, but DHCP received.
• Flashing green when internet is working.
On repeaters, the multi-color WiFi LED has the following statuses:
• No color until speed test (dashboard check-in) is performed.
• Red color if the speed to the gateway is less than 1Mbps.
• Yellow color if the speed to the gateway is between 1Mbps and 2.5Mbps.
• Flashing green if the speed to the gateway is more than 2.5Mbps.
• Blinking red while the node is in “lonely” mode.
• Blink yellow while the node is in “ophan” mode.

Gateway and Repeater:
Flashing purple: Pre-boot phase.
Flashing yellow: Starting up.
Flashing red: Firmware Upgrade (Device is now upgrading firmware).
Flashing white: Configuration change Access Point not ready.
Blinking red: Internet test fails, there is no default route.
Blinking white: CloudTrax Check-in failed.
Blinking yellow: Key must be paired again.

Gateway only:
Fixed teal (green / blue) CloudTrax check-in was successful.
Flashing purple: IP obtained via DHCP, but internet test fails.

Repeater only:
Fixed green: The check-in was successful and the speed is above 2mbps.
Flashing green: The check-in was successful but the mesh speed is below 2Mbps.
Flashing yellow, then green: The device is in Orphan Mode.
Flashing red, then green: The device is in Lonely Mode.

Orphaned nodes are nodes that do not run on the same firmware version as the rest of the network.

If four internet checks fail in a row, the node will fall back into 'lonely' mode. The node assumes it is running on the wrong WIFI channel (the channel number could have changed). In “lonely” mode, the node scans all channels hoping to find internet elsewhere. Scanning all channels takes about 5-6 minutes.
Note: In this mode the SSIDs are disabled otherwise the node would not be able to scan channels.

In Cloudtrax, under the advanced tab, you will find the option “mesh encryption”.
It is recommended to always enable this option. If this option is off, and there is another Cloudtrax network nearby, these two networks can mesh with each other. This ensures that you connect two networks. This allows you to get IP loops and it is possible that you suddenly get the IP address from the DHCP server of the other network.

If firmware 6.3 (or higher) is installed, the “Application Reporting” (DPI) function can be disabled. If this is off, you will no longer see in the statistics what type of data is going over the network (YouTube, Facebook,…), but when DPI is off, the throughput speed will increase a lot. Our advice is therefore to turn this off by default. You can then turn it on temporarily whenever you are interested in the DPI info,
This option can be found under: Configure | Advanced

If all access points are wired, the “APMesh” function can be turned off. You do need firmware 6.3 (or higher) for this. If this is off, the access point will be faster and there will be no more chance of IP loops in the mesh network. Our advice is therefore to turn this off when all access points are all wired.
This option can be found under: Configure | Advanced

If you do not have a splash page running on an SSID, the “DNS Intercept” function can be disabled. This makes the DNS messages transparent to the access point and allows it to handle all messages through the configured DNS server. If the “DNS Intercept” function is enabled, the access point intercepts all DNS messages and forwards them to a DNS server. It is therefore necessary to enable the “DNS Intercept” function if you want to use a slash page. However, when no splash page is used, it is better to disable “DNS Intercept”.
This option can be found under: Configure | SSID1, SSID2, SSID3, SSID4
