Generic zigbee lights intermittent problem with iris and hue motion sensors

problem is HE has the weakest radio signal I've ever seen, compared with Iris, ST, Lightify & Securifi.
Hubitat definitely has the best platform and capabilities, minus the radios. We compensate by adding repeaters, which provide the end devices more than a single path back to the hub, should 1 path be compromised by other signals or building materials. And bulbs can cause issues, especially if they are ZLL and not ZHA. Even if they are ZHA, depending on the guts they can drop zigbee messages. Also be aware of the dreaded "zigbee network offline" issue, that I am plagued with currently.
