Recomendations for switches/ dimmers

Hello I am completely new to this forum and to the world of HA. I live in a rental and have been thinking of incorporating some IOT devices, I am planning to build my own hub with a raspberry pi and a zigbee stick, the devices I am thinking to add are a couple of yeelight smart lights and a couple of swhitches and dimmers . I have been reading a lot about home assistant and I am very excited to start my journey. I have a few questions and would appreciate if someone could help me I have been looking at ikea swithces , and I also found a yeelight dimmer online. my question is are there any wireless dimmers that are good for budget and also good quality that do not required any electrical work to be done (as I mentioned I live in a rental), I am looking for something that can be attached to the wall and can be used to control the lights and also dim them.

what options for switches and dimmers are out there that are compatible with home assistant and do not require any electrical work to be done?
