New Ikea Fyrtur blinds draining battery fast (and uses a different ZHA quirk than my old blinds)

Configuration
1

Hi,

I have been using 4 Ikea Fyrtur Blinds with ZHA for over a year now without any major issues. They open and close once a day and the battery lasts very long. I only had to recharge them once in a whole year. My coordinator is the Sonoff 3.0 (TI CC2652).

I recently bought 2 more blinds and integrated them also in ZHA. While they work, their batteries drain very quickly (in roughly 4 weeks). According to ZHA, all blinds are on the same FW. But, I noticed that they use different ZHA quirks?? I have no idea how that can be, but it is the only difference I can immediately spot.

For all the OLD blinds (which have no battery draining issue), I can see this in ZHA device information:

Firmware: 0x23088631

Zigbee info
IEEE: **************
Nwk: 0xb472
Device Type: EndDevice
LQI: 48
RSSI: Unknown
Last Seen: 2022-09-10T13:23:36
Power Source: Battery or Unknown
Quirk: zhaquirks.ikea.blinds.IkeaTradfriRollerBlinds2

But for the 2 new ones, that have battery drain issues, the Zigbee information says:

Firmware: 0x23088631

Zigbee info
IEEE: ********
Nwk: 0x991b
Device Type: EndDevice
LQI: Unknown
RSSI: Unknown
Last Seen: 2022-09-09T07:24:51
Power Source: Battery or Unknown
Quirk: zhaquirks.ikea.blinds.IkeaTradfriRollerBlinds

Notice the quirk is different. As far as I can remember I never changed anything regarding the ZHA quirks. Does anyone know what can be going on? And if this is indeed due to that different quirk, how can I make sure the 2 new blinds use the same quirk as the old blinds?

p.s The LQI is unknown because the batteries are charging at the moment, but the new blinds are actually closer to my coordinator and I saw very similar LQIs. I don’t believe it is a network reliability or poor connection thing.

I think that this is not linked to the quirks.
Quirks are here: https://github.com/zigpy/zha-device-handlers/blob/b98948e7b6538ab31d87330bba1793e0eb65de11/zhaquirks/ikea/blinds.py
The replacement part is the same. There are two quirks only because blinds don’t have the same signature.
So maybe it does not have the same internal components. Were you able to compare batteries specs?

@tjafbe did you get any further in figuring out the battery drain? The three blinds I have seem to last about 2-3 weeks before they stop working and when you press the physical button on a blind it flashes white 3 times. However ha battery status still thinks they have 40%+ battery?

Actually it would appear it sorted itself out. I wish I could tell you something more concrete, but I just recharged the batteries and they have been going strong ever since. Maybe the first charge was not fully charged, or the batteries needed some cycling? I don’t know, while the first charge only lasted a few weeks, now almost 7 weeks ago after recharging, the batteries report in HA at 90%.

I know that is not very helpful …

it gives me some hope at least so thanks

Apologies for reviving this but I have 4 sets of these blinds I’ve purchased over the course of the last 3 years. So they are varying ages and one is definitely slightly different (the buttons are raised on the newest ones).

Anyway I have this issue since connecting them to Home Assistant. I ran them just fine for a couple of years through the Tradfri hub into HomeKit, but since switching to HA I thought great, I can get rid of another hub. But now all of their batteries die within weeks :frowning:

So if anyone does come across this and has a more concrete fix I would be very happy to know what it is.
