Hi all, wanna ask, recently I renewed my contract with Time (same plan + free huawei mesh node) - why do they set an "installation appointment date and time"?

My time is already installed and running well for the past few years. What kind of installation will they be doing? Btw I dont really need the mesh node, so will just keep as spare or sth

If let say, I don't want to use the mesh nodes? Just keep it by the side, would they still need to come into my house?

(Trying to prevent strangers coming into my house during the pandemic)
