Thermometers keep requesting OTA according to Zigbee2MQTT ("Device '...' requested OTA")

[JayFoxRox]

Here are some logs from Zigbee2MQTT (1.34.0 commit: aae7312); zStack12 Coordinator revision 20211115.

According to this, my 9 LYWSD03MMC thermometers (called T1 - T9) "requested OTA" very frequently.
Each of them is running 3001-0117 (20231215).

I'm not sure if this is poor wording in Z2M or if the devices themselves actually request the OTA. If they do, I believe the 5 minutes is a bit excessive?
I tried to figure out if these are actually from the devices and there are a 3 different calls to ota_queryStart which might be responsible?

"Ota" is not bound to the coordinator either, and there's no reporting configured for "Ota" either.
I have 11 other zigbee devices, and none of them show up here (or not as frequently ~ 5 minutes).
Is this a bug?

Personally, I'd also prefer to push OTA whenever I want them and not when the devices deems them necessary. I'm not sure how zigbee OTA works in this regard, but I'm surprised the device asks at all - I thought the coordinator was responsible.
