Hello, I have an Archer MR600 in a room and then a repeater RE450 very closed to a thermostat.

MR600 and RE450 are in a mesh network.

In TpLink setting I see the network of MR600 with 7 devices connected and on RE450 only one devices and isn't the thermostat.

The wifi thermostat tell me when I open it on SmartLife tha the signal is weak and to check UDP and port setting on router.

Why thermostat doesn't connect to the closed RE450? How can I help it to connect to RE450 insteand of MR600 ?

DHCP on RE450 is on AUTO.

Thank You

Regards
