Automation, sensing and robotics • Small actuator or piston to open/close wood burner air vent

Hi,

I need help finding an actuator or piston for the following project...

I have a wood burner and want to be able to open the air vent via remote.

The air vent is opened/closed by pulling/pushing a rod at the front of the stove (see image below).



I want to be able to open/close the air vent via remote so for this I'm thinking I need something under the stove and attached to the rod somehow and be controlled via a Raspberry Pi by remote control... Or is there a simpler way?

I would also like to be able to open/close the air vent manually so it needs to freely be able to move and should not 'lock' the rod in place. Is there a linear actuator that works like this exist?!... Or perhaps a pneumatic air cylinder might be best.

The stove usually reaches temps of 150°C, and rarely goes over 250°C. I'm thinking of a way in which I can have the actuator below the stove on the hearth so the main body will not touch the stove and be damaged by these high temps (also thinking about adding a form of heatsink to further protect it... This is a separate issue though I guess.
