First experiments show that your new code works. However, when I use the speed setting in the lovelace fan card it also changes the light setting. That's not expected for a fan speed setting.

[kongo09]

Interestingly, HA created new entities with new entity IDs so that I now have duplicates. Is that expected behaviour?

[betaboon]

the entity-id issue is somewhat expected as this integration generates the unique_id from {model}-{product_id}.

as for the light settings: i don`t have a clue how that is happening as the code doesn't even touch that setting.

edit: i just checked with my device (AC4236) using the official app:
all speed modes enable the light+background-light, even the sleep-mode. the sleep mode disables it quickly after tho. so i would consider this to be expected

[kongo09]

I just checked the AirMatters app: changing the fan speed or mode definitely does not change the light setting.

[betaboon]

@kongo09 that's interesting. maybe the app remembers the light setting and sends a separate request. or it uses another interface.
I'm unsure what i can do here, as the requests that we send when setting the speed don't touch the light settings at all.

maybe a pcap of the network-traffic between the app and the device could help ?

[kongo09]

This drives me crazy. Now I see the same erratic behaviour with this device as I saw with the AC2729. Using the HS on/off switch to switching it off indeed switches the device off, but the toggle goes back on again. Working just with the fan-speed setting seems to be more stable.

Could you provide a debug log of the situation?

[betaboon]

i just pushed services for:

• child lock
• display backlight
• light brightness
• humidifier function
• humidity

it would be great if you could test it :)

[kongo09]

Could you provide a debug log of the situation?

I did that over at #4 . However, for whatever reason, this morning the device started to behave. All seems to work.

i just pushed services for:

This device does not have a humidifier function or humidity readings.

AC2889 seems to work fine. As kongo09 wrote, the AC2889 doesnt have humidity functions/sensors.

Brilliant! I have 2 http purifiers (which work very well with other plugins) but could not get the COAP one to work consistently. Will test for a few days and report back but so far all speed settings seem to work. Not much luck with services yet.

@kongo09 - my devices all turn of light and display light (where applicable) when set to sleep mode. Suspect this is built in and kind of makes sense to me.

Can still switch on the purifier in Home Assistant (also after days), but the switch in Lovelace goes back to off (Purifier still runs). To switch the purifier off, I need then to switch it on and right away off in Lovelace. Will check the log.

@tunip see issue #15 which I just opened. Your description seems in line with my issue, can you check if a home assistant restart works and if you can find the same "handshake" in your logs?

[tunip]

@ronaldt80 home assistant restart is a temporary workaround. A few hours/days later, same behavior. Enabled debug logging and lets wait, what happens.

@kongo09 - my devices all turn of light and display light (where applicable) when set to sleep mode. Suspect this is built in and kind of makes sense to me.

It is a (built-in) feature, not a bug. You don't want to illuminate your whole bedroom at night, at least I don't. 🙂

Anyway, I've integrated my AC2889/10 with this custom component only yesterday. Biggest issue was the security setting in my WiFi that was set to WPA2/WPA3 and I had to downgrade it to WPA2 (CCMP) or the purifier wouldn't connect.

Can I help you with anything?

[betaboon]

I'm closing this issue as the initial support for this model seems to be working.
