HACS with Two Heatmisor Neo Integrations

Hi Cogniscenti,
I’ve got HA Supervised running on Raspberry OS with HACS installed and the Heatmiser Neo integration up and running. However, I have two Heatmisor Neos running in my house. When I install both, the second one I install has its thermostats running correctly on the frontend, but the first one installed has all it’s thermostats showing “Unavailable”.
Is there a way of showing both Neo’s thermostats please?
Thanks for the help!
