The number of clients equals the number of simultaneously connected MQTT clients (devices, applications, etc.).
We do not count the clients with the “not available” status.
The traffic accounts for all messages entering or leaving the broker. In other words, it represents the amount of data transmitted from and to the broker. The MQTT broker is responsible for logging this information.
Here is an example of how we calculate this limit:When a client publishes a 100 byte message on a topic, it spends 100 bytes of your traffic limit. If there are no subscribers to this topic, this message will not be transmitted further. Therefore, in this case no traffic is spent on outgoing messages. However, if there are 5 subscribers on this topic, the broker will transmit this message to them and account for another 500 bytes of traffic (5×100 bytes). In the example with 1 publisher and 5 subscribers, the message accounts for 100 bytes of traffic when entering and 500 bytes when leaving the broker, totaling to 600 bytes (100+500 bytes) of transmitted data.
If your monthly traffic on a hosted by Cedalo instance exceeds the allocated traffic limit, you will be charged $ 0.128 (€ 0.117) per GB for annual billing periods, and $ 0.16o (€ 0.147) per GB for monthly billing periods.
When running the MQTT broker on-premises, you may also exceed traffic quota for a billing period traffic quota. In this case, we will not pause the MQTT broker operation, but will keep it running until the end of the billing period. Based on the information for the current period, we will adjust your subscription plan for the next billing cycle and account for the sufficient amount of traffic to cover your operational needs.
The MQTT broker is hosted by a renowned cloud provider, Hetzner, known for its best-in-class data security, performance, and availability. The servers are located in Virginia, U.S.; in Oregon, U.S.; in Finland; and two locations in Germany. During the onboarding, we will ask you where you want the instance to be located. If you require hosting at a specific hyperscaler and/or in a specific geographic region that is not listed, please email us at [email protected].
To update your billing or contact information, please use our Customer Portal.
It is possible to upgrade your subscription at any point in time. To perform the upgrade, email us at [email protected]. Once you do it, you will be billed a prorated amount to cover the rest of the billing period.
If you want to downgrade your subscription, please email us at [email protected] at the end of the billing period and tell us which new plan you want to use. In this case, we will update your license and feature set accordingly. So, starting from the next billing period, you will pay the price for your new subscription only.
You can also cancel your subscription using our Customer Portal at the end of your billing period.
At this moment, we accept Euro and USD payments. If you wish to make payments in another currency, please send the details to [email protected]
Are you part of a bigger organization with formalized billing processes? Your organization cannot pay by credit card but requires a written offer, order by an official purchase order from your ERP, or payment by wire transfer? In these cases, please contact us at [email protected], and we will get in contact with you to onboard you by your corporate guidelines.
