Fan Control

[lfiocco]

How hard is it to change this plugin to control the HVAC fan. my setup includes an air exchanger that uses the fan from the air handler to exchange. Manually flipping this means I get more fresh air into the house when on.

Right now I have to use the Ecobee interface to control the fan. Automation and Siri control would be super cool.

I'm not sure, to be honest. The Ecobee API isn't super detailed, so it's a little hard to know what it actually does.

That's the closest thing I could find, basically set a hold temp with the fan speed set to full? I'm not sure if that would actually work or not, or if a hold is what you're looking for.

I just tested and this is possible, you can use setHold with fan: on and fan: off

                const awayBody = {
                    'selection': {
                        'selectionType': 'registered',
                        'selectionMatch': '',
                    },
                    'functions': [
                        {
                            'type': 'setHold',
                            'params': {
                                'holdType': 'indefinite',
                                'fan': 'on',
                            },
                        },
                    ],
                };

I too am interested in this. My question now, is could we also expose the "holdType" via some HomeKit control? I often want the fan to run for 15/30/60 minutes and then return to it's regular schedule. I haven't looked at the HAP in quite a while, but I cannot think of a good control for this. I suppose we could just expose six switches, one for each preset duration. It's not elegant, so any other suggestions would be welcome.
