I personally wouldn't bother, normal alkaline batteries have lasted for months.

I've had mine for at least 2 years and haven't changed them yet. Most of that time they were connected to the hue hub.
Hi
I suspect that it is about 15 sec, not sure. I’ll do a test and let you know
I'm using the Hue sensors directly with C4, and have the lowest retrigger time possible.
No issues with them.
Battery is going on 9 months

hi all - do the Cygnett Smart Window & Door Sensor work fine with hubitat now? I only just started looking again after not buying anything for 2 years here in aus and harvey's / good guys sell lots diff smart stuff finally.
They look like zigbee based and should work with generic zigbee drivers (either built in or here)
In any case @ $18 it's not a huge sum for a punt. I bought a Cygnett motion sensor not long ago and markus' drivers worked fine.
Yep they work fine, i have about 5 of each at the moment with a few stashed away for any new ideas i have.
Fantastic thank you . Bit of a luxury being able to buy this stuff from a store now

Hey sorry I missed your message @Gradenko. I've never had any problem at all with the Fibaro modules, but they are RGBW modules controlling LED strips. I don't remember if I had to do any extra configuration when they were installed, but I've definitely not had to give them any attention since then.
I visited my local IKEA last night and noticed that they now have Tradfri power outlets for $20. (Or $30 with the button that isn't supported by Hubitat yet).
It doesn't have a physical button, and doesn't have power monitoring, but presumably will work as a Zigbee repeater. Same price as the official IKEA repeater which only has a USB outlet.

Do they report power usage?
No they don't.

Always nice to have cheap, locally available ZigBee device options. It feels like we're finally seeing ZigBee devices available from local retailers other than specialist smart home places. Great for competition and subsequently prices!
FYI: The Telstra outlets are Zigbee, they’re cheaper, they include power monitoring and have on/off button.
I have 3 of them 
, was just curious to know if they did.

Hi all - still on the hunt to replace this old thermostat with something Hubitat compatible. I have identified 4 options on AliExpress that I am confident can be wired correctly in place of my existing thermostat, but I'm not so sure about the pros/cons in terms of hooking up to Hubitat. I'd really appreciate some thoughts from those with more experience.
Here we go:
- Tuya thermostat (wifi) - Tuya but Wifi, I guess I could control via the Tuya apps and connect via Google Assistant and control (cloud only) via Hubitat?
- Mijia thermostat (wifi) - Same hardware as #1, but flashed with Mijia software so compatible with their ecosystem. I would have to connect to Hubitat via Google Assistant as well. One advantage is I do have a few other Mijia devices that I use via their app but automation would still need to happen via Hubitat (to connect to my other sensors)
- Moes Thermostat (zigbee) - Zigbee so hopefully can connect in to Hubitat directly, but looking at the community chat, nobody has been successful getting a driver working (Tuya as well)
- Tuya Thermostat (zigbee) - Another Zigbee option, likely same underlying Tuya hardware as #3, not sure of driver/compatibility for Hubitat either. I guess being generic Tuya means there's a chance I could somehow get it working with Hubitat natively which is the ideal situation
The tradeoffs seem to be, Wifi will likely work but via Google Assistant, so only Cloud-based. But the Zigbee ones may not work easily but if they do it will be a nicer setup as Hubitat can interface directly.
Thoughts?
None of the above.
Imo, the Zen Zigbee units are the best available atm for use with HE. I've had mine for about 6 months now and am very happy with them. Very high WAF too - my wife likes them better than our old nest's too.
Hah, thanks. But unfortunately I don't think I can use the Zen or any 24v thermostat. I actually have a Nest Thermostat from my previous house which I can't use either 
My old thermostat is 240v switched (on/off only) which is connected to a Hydronic system. There isn't many Zigbee (or even Wifi) options that support that kind of set up.
Ah that sucks. 
You could use the 24v output of a thermostat to trigger a 240v relay.
Or, you could do away with a thermostat, and use a simple Zigbee switch module (or Wifi, etc) to switch the 240v line for your hydronic system. Use Hubitat's virtual thermostat, or program your own smart thermostat to how you want it. I created my own thermostat logic in Node Red, and I'm pretty happy with it. I don't have a screen to monitor/control the thermostat, but I find that I've now got the logic set up well enough that I really never need to adjust anything.
ps. You would also need a device to measure temps. I actually use an average of several sensors in the house for this reading.
