Using EmberControls - One of my entities goes missing, appears to be renamed by the HA integration?

Hello There. Ive only recently installed HA for the first time, and its up and running. I have two heating controls systems in my house. I have EPH Controls Ember and i have HeatMiser Neo. I have both up and running.

I am getting a strange issue where randomly one of my eph entities “Old House” goes missing.

When i open my Ember app on my phone, i can see that my Old House stat has actually been renamed “Hot Water”, which is a duplicate of another stat!

Any advice?
