E1743 reports NULL actions when clicking buttons

[EPMatt]

Bug information

Device: IKEA E1743
Firmware: 2.2.010 (latest)
Zigbee2MQTT version: 1.18.3

Description

Interacting with the IKEA E1743 On/Off switch produces an additional null action after the empty "" action. This accidentally broke all my smart home automations which had this remote as a trigger.

I don't know when this issue started to occur, but a few versions ago (~1.17) I wasn't experiencing this problem.
I'm reporting here since I guess the issue is related to this package.

Thank you for maintaining and developing such an amazing project! 🚀

This is due to HA now requiring all attributes on publish, see Koenkk/zigbee2mqtt#7032 , you should update your automations.

Hi,

thank you for the quick reply.
I've just taken a look at the PR, didn't spot it before. I'll update my automations and blueprints accordingly to the implemented change.
Sorry for the bad issue I reported. Thanks again!
