https://devzone.nordicsemi.com/f/nordic-q-a/46484/mesh-profile-specification----models-and-elementsHi, I am looking for ways to reduce the Element count on the nodes that have multiple instances of same model. I was going through the Mesh specifications and I found this in the profile specs: It says that an element can&#39;t contain models usingen-USTelligent Community 13Fri, 26 Apr 2019 12:42:39 GMThttps://devzone.nordicsemi.com/thread/184076?ContentTypeID=1Fri, 26 Apr 2019 12:42:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3e009df2-3317-4664-971b-aaeecc1c7964Omkar Kulkarni<p>Hi,<br /><br />The requirement of `element can&#39;t contain multiple models using the same messages` - arises from the more high-level design that, an element on the mesh node represents one actionable entity. This entity contains states that can be set or read by sending messages to that element address.&nbsp;<br /><br />With respect to nRF Mesh SDK, it is not only sufficient to have different opcodes, but you will also need to use a different model ID. Essentially, you will have a different model altogether even if it tries to do the same task as the original model.&nbsp;<br /><br />It is not a good idea to instantiate such overlapping models on the same element. If you need multiple instances of the same SIG models, you must instantiate them on separate elements.&nbsp;<br /><br />Regards.</p><div style="clear:both;"></div>
