Thank you for the quick response. I had thought that might be the case. Hopefully a Shelly device that can do what I am after will be available in the future. Looks like I will need to find another way in the meantime though. Thanks again.

I have a use case that requires hot air to be extracted from a space using an inline extractor fan. I have not selected the fan yet so don't know the exact power specifications for it. However, it will be a 150mm (6'') unit that can move up to ~400 CFM and can operate at variable speeds.
My aim is to be able to control the fan on/off state, as well as variable speed settings, based on the temperature in the space. Ideally this would make use of the Shelly H/T sensor to first measure the temperature and then control the fan. I know that I can get the fan to turn on this way using a Shelly H/T, a Shelly 1 and Home Assistant (probably also just through Shelly Cloud as well but I'm not sure as it is not my preferred method for this).
My question then is would it be possible to use a Shelly Dimmer 2 for this to enable control over the variable speeds as well? If not, is there another Shelly device that I should use for this use case? Thank you in advance for your suggestions.

I have just installed the Shelly with the method you describe and everything now works perfectly! Thank you very much for your help, it is greatly appreciated. I have marked your answer as "Best Answer" already but please let me know if there is any other protocol on the forum that I should follow as well. Thanks again!

My apologies for the delay between my responses, I have been at work.
I have done some investigating and it would appear that the Live wire is coming in to Switch A and the Switch Live wire is from Switch B. However, I need to mention that the diagrams I have sent have Switch C and B labels mixed up. The switch labelled Switch C is what I have been referring to as Switch B in our conversations (including above) and the switch labelled Switch B is what I have been referring to as Switch C. My apologies for this mix up.
Thank you again. I hope this makes sense. Please let me know if you require any other information.

Hello, thank you very much for your message and willingness to help out.
I have prepared a wiring diagram showing the switches and the lamp as best I can as I do not know how the circuit is laid out in the walls and celling. The original circuit contains Switch A, Switch B and the Lamp. Switch C is a switch for another lamp in a separate room, but I have included it in this diagram as it shares a wall box with Switch B. This diagram is as follows:

I had attempted to install the Shelly 1L at the same location as Switch A, leaving the wiring as it was in the wall box for Switches B + C. I have since uninstalled the Shelly and so have not got a photograph of the device installed. However, the diagram below shows how I intergrated it with the existing circuit:
Looking forward to hearing back from you and thank you in advance for your assistance.

Hello All,
I am not sure about forum etiquette, so apologies if i have posted in the wrong place but i thought it would probably be best to start a new thread for this.
I have purchased the Shelly 1L and Bypass for a 2 Way Switch, single light, setup and have fitted the bypass without issue. However, the wiring in both switches are as shown in the attached image and I have wired in the shelly 1L as suggested by Dimitar Dimitrov, and shown in the image below. Sadly though, at this stage all I can do is turn the light on/off via the shelly and the switch it shares a wall box with. If I then flick the other switch on/off it cuts power to the shelly and the switch in the wall box with the shelly.
Unfortunately i do not know the circuit is wired in the walls, all I know is what i have posted above and that, before installing the Shelly, both lights would alter the state the light was in when flicked - regardless of the current state of the other switch or the light itself.
Any help/insight here would be appreciated. All I can think of is that the light itself might be in between the two switches in the circuit and that putting a Shelly 1 in the ceiling with the light might work. However, I have the Shelly 1L already and would prefer to find a solution that utilises that if possible.
Thank you all in advance and i look forward to hearing your suggestions.
