Hi @julienL
I was thinking of taking these heads from Moes (63.27€ for both): https://fr.aliexpress.com/item/1005002431040917.html
I attach great importance to the possibility of manually controlling my home automation. This model seems to allow you to turn the ring to change the temperature.
On your side, can you confirm what you are using and if it is controllable via Gladys and manually?
If it’s not yet fully managed in Gladys, I could always use the Nouvelle vidéo: Intégrer Node-RED avec Gladys Assistant en MQTT! if I understood correctly 
Thanks!
