You could request device event history from the Maker API.. and maybe parse/store those. Might have to play around with deduping.
http://[HE url]/apps/api/[maker instance id]/devices?access_token=[the access token]
http://[HE url]/apps/api/[maker instance id]/devices/[Device ID]/events?access_token=[the access token]
To do a dump just http request a list of devices then a split node which creates separate messages for each device then another http request to grab each devices event list...
Something like this maybe:
Not something you want to run too often.. note the "random" delay node is a random delay per request so as not to spam the HE hub. The devices you want to record history for should be added to the Maker instance.
