Hi, I purchased a Philips Hue outdoor motion sensor, had to connect it directly to Hubitat as the Hue app doesn’t expose it to the hub like bulbs. The problem is that the sensor keeps disconnecting from Hubitat and the only way is to reset it. I purchased another one and it has the same behavior.
Any advice here or I have to switch to a z wave sensor and not Zigbee
Ok, then I think you need to continue down the line @ogiewon was heading with comm's back to the HE hub. Did you find out the channel your 2.4Ghz Wi-Fi is running on?
These are good choices, as they do not conflict with one another, and also are good choices so long as your 2.4GHz WiFi channels are 1, 6, o and/or 11 and use a 20MHz channel width. This will avoid Zigbee/WiFi overlap.
From what you posted above, it appears all of your Zigbee devices may be battery powered. Is that correct? If so, I believe you need to add a few mains-powered Zigbee devices that will act as Zigbee mesh network repeaters, thereby strengthening the signal overall. This will help your outdoor sensor(s) stay connected to the Zigbee mesh network.
There are numerous threads in the forum discussing what type of Zigbee devices users like to act as Zigbee repeaters.
Unfortunately, Zigbee devices can only “repeat” for other devices on the same Zigbee mesh network. Hubitat and Hue each create their own Zigbee mesh network, which is why it is always good to make sure they are using different channels. I added a graphic to my earlier post which shows why channel choices are so important.
As said, if you have no mains based repeaters you will have an incredibly weak mesh. Get some sengled outlets on amazon, these repeat nicely (the new oval ones not the old square ones). I would not connect your hue bulbs to your hubitat mesh. Those are ZLL based zigbee and DO NOT repeat well for ZHA based zigbee devices (your sensor and outer regular zigbee devices) The exception to this are Sengled bulbs (they do not repeat) or zigbee 3.0 bulbs. So keep your bulbs on the Hue bridge and get some of these and attach them to Hubitat (This is a two pack)
