When you say “install Gladys on a Tuya panel,” do you mean displaying the Gladys interface on it, or running the Gladys server directly on the panel?
In practice, I recommend installing Gladys on a mini-PC. Then, the interface is accessible from any browser, so it can potentially be displayed on your Tuya panel if it allows it.
Regarding 5-wire controlled heating, yes, it’s quite feasible
There are Zigbee modules that work well for managing 5-wire controlled heating.
I saw that you can put « home assistant » on a panel. Indeed, I would have preferred to put Gladys directly on this panel to avoid an additional device. The Tuya T6E panel runs on Android and is equipped with Wi-Fi, ZigBee, and Bluetooth. I saw that it is possible to install Gladys on a mobile phone that also runs on Android.
Gladys recognizes micro pilot wire modules and is capable of controlling its 5 commands; I admit I didn’t quite understand your response .
