Force Fan On on Ecobee Thermostat?

[dusk summit]

I'm looking into getting a smart thermostat controllable by HA so I can, based on sensors and rules of my own, start the fan of my HVAC.

On my current Carrier thermostat (same brand as the furnace itself) I can force the fan to be on.

I'm looking at an Ecobee thermostat, and before spending money on that, I want to make sure I can do that. I stumbled on this page and I'm not totally sure, but it seems to mean that I wouldn't be able to using HomeKit.

Am I reading things wrong, or am I missing something?

I don't really understand what you are trying to show by linking to that source code, but I have an Ecobee Premium connected via HomeKit and can turn on the fan. The on-time seems to follow the device's configured hold setting (2 hours for me).

Great. It answers my question.
The source I linked was because it's what I stumbled upon when trying to research it myself.

Ah, I see, I didn't click on the line link, just the file. I see:
⁨```
# r/w, 100 for on, 0 for off/auto
# https://support.ecobee.com/s/articles/Multi-Speed-Fan-installations
VENDOR_ECOBEE_FAN_WRITE_SPEED = "C35DA3C0-E004-40E3-B153-46655CDD9214"

Not sure if that's the functionality being used for mine, I have no experience HomeKit besides this thermostat.

Yeah, but since you're saying it works for you, it means that it would 98% work for me too so I'm alright with going forward with the purchase.
