Limit for number of REST sensors on an Philips HUE 1.0 bridge?

I’ve a presence detector, 2 dimmers and an Philips HUE 1.0 bridge and I’m currently trying to have a total of 8 REST based sensors on 0.49.1.

Right now, it seems like I’ve it some sort of hard limit of rest calls, when I’m restarting HA, which gives me the following error and a missing sensor. 7 sensors causes no issues.

2017-08-01 19:58:30 ERROR (SyncWorker_9) [] Error fetching data: <PreparedRequest [GET]>
2017-08-01 19:58:30 ERROR (SyncWorker_9) [] Unable to fetch REST data
2017-08-01 19:58:31 ERROR (SyncWorker_3) [] Error fetching data: <PreparedRequest [GET]>

The HUE hub is apparently choking on the 8 requests at start up.

I’ve looked into trying to create the sensors based on one single REST request, but that is apparently not possible, as each sensor needs its own resource url.

Any one seen the same issue? Could an upgrade to a V2 bridge be a remedy?
