I am new to Hubitat. I am looking for an outdoor temperature sensor that will work with the C7? It can be either an interior unit with a temperature probe that goes outside or an outside unit. I would prefer one that plugs in, rather than a battery unit, as it will be used at a cabin in northern Canada (temperature drops below minus 40 sometimes, and cold kills batteries.
Thinking a little out of the box but HomeSeer Floodlight Sensor G2. As the name says, its a floodlight motion sensor, but it also has a temperature sensor that has been pretty accurate for me.
I just looked up the HomeSeer Floodlight Sensor G2. It looks like it might be exactly what I need. How is the unit working for you? There seem to be quite a few comments that the drivers don't work properly and the temperature is off by quite a bit.
For a different use case - Can the unit sensor turn on other lights (both connected to other G2 sensors and smart plugs)? If so, I could use a few of the units to light up the property and driveway.
It took me a little bit to figure out the manual configuration (kept putting it in test mode) but once I did it’s been a champ. Using the motion to turn on the attached lights as well as a trigger for other lights in the area. On the flip side, I also use it to turn on it’s attached lights when another motion sensor becomes active. Temperature has been consistent with a couple of weather station sensors in the same immediate area.
It sounds perfect. For the primary use case, I will install the unit under the cabin, and have it turn off the Sinope water valve on the well if the temperature drops below freezing.
For my other use case, what I would like to do is have sensors at the gate, beach, workshop, and cabin that will turn on lights throughout the property. Do you have any lights that are not connected to a sensor, which are controlled by the sensors? (I would like to have sensors at either end of the driveway, and lights every 50 feet or so) I have been able to find Zigbee and Z-wave switches and receptacles, but no light sockets. I found a Skylinkhome Screw-in 60W Wireless Lamp Module (LX-318) for $20 at one supplier that I use, but I think that it only works with other Skylinkhome devices. My thought was that a Zigbee or Z-wave light socket would be a lot cheaper than the G2 sensor.
This maybe difficult a range to get useful/accurate temp readings...
According to the manual:
Working Temperature -4°F - +104°F
-4 F is - 20 C. I would want the rule to close the valve at 0 C = +32 F. I have had problems with electronics when they get too hot, but never when they get cold (only problems with mechanical, batteries, and fluids). I wonder what would happen to the unit when the temperature drops below -4 F?
No individual sockets, except for the G2 all of the other lights are on Inovelli dimmers/switches. At my old house I did have a couple of zigbee bulbs that I activated via external motion sensors and a webCoRE piston.
I’ve got one rigged up to a LED floodlight that I am no longer using. I recently replaced this floodlight with a Ring floodlight camera. Willing to sell and ship it to you if interested. Works greats just don’t need it any longer. PM me if interested.

I'd suggest the Fibaro Smart Implant. You can use up to 6 external temperature probes DS18B20 with it. Just deployed one and it works very well with HE, and serves as a nice zwave repeater too. It's tiny, but requires a 12 V power supply. The temp probes are inexpensive and accurate: https://www.amazon.ca/gp/product/B08SQX618X/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
I'm also in the cold north (-35C is not unusual) and have had great success with powering sensors with a bit of solar. This is a SmartThings door/window multisensor setup that has been running 24/7 for three years, winter included. I have two of them powered this way for my detached garage doors as cold was killing the small lithium cells in 1-2 months. Solar cell is a 5V amazon deal that includes a diode..no charge controller required due to very low charge rate.
I'm using some older FGK-10x (Fibaro door sensors that allow connecting an external temp probe) with this setup (solar powered like above, but with 3 x AA cells). These have been running right through winter with zero issues.
I use a bunch of these sensors to manage my pool solar, and as of the weekend, am also tracking ERV efficiency with them. Link below is to my "live" data feed.
If you're trying to control "dumb" lights via a few sensors, I'd take a look at the Aeotec Nano Switches. They are small relay/switch (neutral required though!) that I use to automate fans/lights etc. You can normally fit them in a standard electrical box, behind an analog switch if needed. They also serve as zwave repeaters which I think you'll need in your scenario.
