Fans are only created for the first thermostat that is found when the home has multiple thermostats

If the home has multiple thermostats, then only the first thermostat has a fan accessory created.

I believe the issue is in src/Platform.ts.

This code:

const thermostatDevice = devices.find(device => device instanceof Thermostat);
 if (thermostatDevice && this.config.showFan) {
     const uuid = this.api.hap.uuid.generate(thermostatDevice + ' Fan');
     deviceInfos.push({
         device: thermostatDevice,
         uuid: uuid,
         category: this.api.hap.Categories.FAN,
         existingAccessory: this.accessories.find(accessory => accessory.UUID === uuid)
     })
 }

Should be:

devices.filter(device => device instanceof Thermostat).forEach(thermostatDevice => {
     if (this.config.showFan) {
         const uuid = this.api.hap.uuid.generate(thermostatDevice + ' Fan');
         deviceInfos.push({
             device: thermostatDevice,
             uuid: uuid,
             category: this.api.hap.Categories.FAN,
             existingAccessory: this.accessories.find(accessory => accessory.UUID === uuid)
         })
     }
 });

Thank you @ic04n! Nice PR, it's now merged and 1.1.17 is released.

Thanks! Great plugin by the way, glad to contribute. I just sent another pull request actually, because there was an issue with unique uuid generation. I think the original code was not properly converting the thermostat name to a string when generating the uuid for the fan, but it never was an issue because there never was more than one fan.

Also merged and released.

Oops, screwed that up a bit (this is the first real PR I've gotten for this repo). v.1.1.19 should be good to go

Nice! It looks like it's working now. Great teamwork :)
