Turning non-wifi thermostat into wifi thermostat with shelly INU

Hello there,

I am new to Shelly universe and I do not understand anything about power wiring. I have some shellys on my plugs around the house, but someone wired the first one for me and I copied the setup for the rest of plugs.

Now I have some new thermostats installed when I renovated my house, these are good, allow me to select a temperature and they turn on and off automatically, BUT these do not have WI-FI, so I cannot control them from a distance, nor I can have the temperature information stored or consulted from a distance.

I tried to figure from the Shelly universe which device could help me to gain a connection to these thermostats and I am wondering if Shelly UNI is the one, but I cannot interpret the wiring diagrams myself.

This is the wiring diagram from my thermostat:

This is the diagram for the Shelly UNI - which I have no idea how to read:

Can someone help me understand if the Shelly UNI is a good option for me to have remote access to this and if YES, how should I do the wiring between the Shelly UNI and this thermostat?

Drawings for instructions at a dummy level will be much appreciated.

Thank you very much.

Regards,

Inês

Hello,

Thank you very much for the answer

I don't want to replace the thermostats, they have less than 1 year and were not cheap. Also, they measure the temperature, they are programable by hour or temperature, the only thing they don't have that I wish they had is WIFI. The boxes in the wall behind the thermostats are quite small, so it's difficult to put a Shelly in there.

But thank you so much for the suggestion, I will keep searching for solutions.

Regards,

Inês
