Zigbee Hub/Gateway with microSD cards

I want to use the Sonoff SNZB-06P Human Presence detector.

I want all granular data from detection events and times to be saved in a Google Spreadsheet

Also I want the data saved locally so I do not require Internet access

What Zigbee Hub/Gateway has 256Gb storage and can enable saving of all data locally?

Is there a low cost option apart from iHost that is £75?

I don’t know about pre-built hubs/gateways, but you can buy a Zigbee Dongle and build your own with a Raspberry Pi. That’s what I did, exactly because I didn’t want cloud integration etc..

Thanks for the idea Shoe..I am contemplating to do that Cheers
