Heatmiser UCM, lightwave UCM and ETH03

[MDKKEN]

Hi,
I am planning on using Lightwave RF,  Heatmiser UCM and ETH03(UCM06+ETH03)

1. Can I have one Universal UCM for lightwave RF and Heatmiser simultaneously?.Or do I need a separate Universal UCM for each - assuming Ethernet connection via ETH03 plugin.
2. For normal work and config will I need uCM06+ETH03 plugin.
3. Will I therefore have three RJ45 connections, two or one?
4. Is better to have Heatmiser RS485, and the other lightwave RF as ethernet in this scenario?

What is most reliable option?
Your help would much appreciated?

Universal UCM cannot be used for Heatmiser

You need a Heatmiser UCM for that

A  Universal UCM can only communicate with one type of 3rd party system at a time so if you have eg LightwareRF and Lutron using Universal UCM and ETH03 you would need 2 universal UCMs and ETH03s

If you have Universal UCM and ETH03, UCM06+ EH03 and Heatmiser UCM + ETH03, these are 3 separate ucms with their own ETH03 with RJ45 so you would have 3 RJ45s to connect to your router
