Describe the bug

When controlling fan via Home app, I can only control the low speed. Trying to change to medium/high speeds will turn off the fan.

In the Homebridge logs, I see the following (which is mentioned in the Common Issues Wiki BUT using homebridge-tuya-web plugin I cannot discover the device).

The device in question is Arlec 40cm Smart Pedestal Fan With Remote.

From the Tuya IoT platform site for the fan I can control the speeds 1-3 and this works.

To Reproduce

Steps to reproduce the behavior:

Control fan via Home app, speeds 2 and 3 (medium/high) turn off the fan.

Expected behavior

A clear and concise description of what you expected to happen.

When set to 50%, change to medium speed. When set to 100%, change to high speed.

Plugin configuration snippet

   "devices": [
        {
            "name": "Lounge Room Fan",
            "type": "Fan",
            "manufacturer": "Arlec",
            "model": "40cm Smart Pedestal Fan With Remote",
            "id": "XXX",
            "key": "XXX",
            "dpActive": "1",
            "dpRotationSpeed": "3"
        }

Is this a issue with the API or potentially a plugin misconfiguration? It is strange that this works via Tuya IoT platform but not the plugin itself.

Hi @psycoticninja, I have pushed a new beta (3.1.0-beta.2). I have made a few changes to the fan controller logic. Can you give it a try on that version and see if that fixes the issue?

[psycoticninja]

Hi @05TEVE, I’ve just updated to the beta plugin and tested this but it looks like I am still seeing the same issue.

Is it possible to provide the Tuya Device Specifications here? You should be able to find this in JSON format from the Tuya API. Device Controls -> Query Properties.

I am guessing that the DP id specified for the speed controls may not be right.

Updated just in case of any unnecessary IDs potentially exposed.

Hi @05TEVE did you ever get a chance to look at this further?

I ended up installing the latest plugin v3.1,0, the issue is still present.

I have Max Speed set to 3 and Default Speed to 2.

Any ideas?

If you use tuya-cli to pull the switch parameters, does that match the queried properties?
