Using the S1 as a thermostat

Hi, Iv got a Vaillant ASHP system, it’s currently using Honeywell hr91’thermostats with the Honeywell module sends a signal that puts the heating on or off.

I’m looking at buying the Aqara E1 thermostats but also using the S1 plus to control the heating, can the s1 plus be wired to send a signal to the valiant system to start the heating ? If not do Aqara do a module for this?

Hello, welcome to the forum.
There are no ready-made solutions from Aqara for your question (boiler control). This can only be done using automations complete with the T2 relay.
