@TrystanLea I’m updating my notes on the various capacity limits of the OEM software solution and wanted to confirm my understanding and fill in a few gaps.

Here is my list of maximum capacities;

- Number of nodes per Account = 100 (is there a limit to the number of subaccounts per main account?)

- Number of 433MHz nodes per emonHub/emonPi2 = 32 (I saw an earlier [post](https://community.openenergymonitor.org/t/my-emoncms-server-rejects-emonhub-data/9790/4) that this limit can be increased, but the [link](https://github.com/emoncms/emoncms/blob/master/default.settings.php#L77) it refers to is dead)

- Is there a limit to the number of Feeds per node?

Thanks,

Gordon

Hello @grod55

- There is a limit of 100 input nodes on [emoncms.org](http://emoncms.org) but no limit on the number of feed nodes (this was put in place due to issues with spurious nodes created from RF data).

- There is no enforced node limit in emonHub. Technically the LowPowerLabs library should support the following spec: [https://github.com/LowPowerLab/RFM69](https://github.com/LowPowerLab/RFM69)

- There is no limit on the number of feeds per node.

Hope that clarifies things for you!

It does - thank you for the info.
