Actually, their own hub did not have the option to update Zigbee devices, at least the SP240 plug I had several of. They were planning to add such functionality to their own hub, but apparently it was not really a priority.
I waited for a year and was in frequent contact with their support desk. During that period they also referred me to Home Assistant and Zigbee2MQTT. In the end, I bought a seperate Zigbee stick and updated all my plugs via Zigbee2MQTT, as the firmware they came with had several issues.
Then I also learned that:
- INNR’s lead software engineer was very active on the Zigbee2MQTT github, providing frequent firmware updates there.
- INNR’s support desk set up a HA/Zigbee2MQTT system to be able to update Zigbee devices at the request of customers, as their own hub was still not able to do so.
Maybe this is the odd one out, but INNR is an example of brand that does share their firmware and promotes using other platforms for performing updates.
