Looking for a remote temp monitor that I could watch the temp in my engine room and cabin. We have Wi-Fi at the dock, what would you recommend?
 
I'm using this from acurite with 4 indoor/outdoor sensors.

Helm, Engine, Cabin and Refrigerator is monitored.

2 downsides. The device requires a wired internet service, and sometimes it goes off line.

To get around these I have it plugged into a smart plug so I can turn on and off (using phone app) to get it back online and I'm using a WiFi extender tied to the marinas WiFi that has a Ethernet port so I can plug it in.

I bought a basic Govee wifi temp sensor for this exact purpose a couple of years ago. It worked well for my purposes, has an app to monitor temp, and you can set high and low temperature thresholds for an alert to your phone. Also tracks and graphic temp trend, so you can see how the engine room or cabin heat up.

I used it on my boat wifi and it worked well. You will have to research what is required to connect to your public wifi sometimes those can be snarky.

With the boat in storage for the winter, I use it in my garage to monitor temps, because we have some exposed pipes. Below are the real-time snapshots from the app.

I have 3 Blink XT wireless cameras that have built in temperature sensing. One on the arch, one facing aft on a windshield pillar, and one mounted in the engine compartment.
 
Been using LaCrosse Technologies temp, humidity, and water monitors for years. The gateway, which hooks up to the internet is a hardwire ethernet port, so you have to get creative with wifi extenders or on board routers (my choice) to connect. Mine sits on my private home network via an air fiber connection between the house and the boat, so I am in pretty good shape for connectivity. Being close to the boat, I use it mainly for alarms on out of bounds temps (A/C quit), dock power outage (can't find the temp monitor), or high water where it shouldn't be. Pretty cheap annual subscription rate for cloud access and alarm notifications.
 
Over the years, I tried both Govee and Acurite but both had issues staying up over the winter, at least for me.
After some research this year I went with SensorPush (https://www.sensorpush.com). I got their G1 Gateway which connects to my router via ethernet but also can do wifi. The Gateway sends the data to a free cloud that I can access with their app. I set it up in October and so far it has been rock-solid.

The Gateway is only about 3 inches square and the sensors about 1 inch. The sensors can be attached with 2-sided tape but also have fittings to use a zip tie to secure the unit to the overhead, which is what I did in the ER.

The app has an overview screen plus an expanded view for each sensor with trends over time. The wiggling temp line in the ER is my bilge heater cutting in and out.

Al, what a great find, the free cloud service is very nice with the history. I use Maretrons remote monitoring with their N2K app, but the one thing that doesn't do is the history. It's nice to be able to see what's going on when your boat is in the water all winter long.

Agree. One thing I've learned and need to do something about is the swing in humidity. I didn't shrink wrap this year and I think the humidity is due to open ER vents. If I go commando again I need to have vent covers.

Yes, I cut heavy plastic and tape up the vents. Makes a big difference. I also have an XtremeHeater running as well, even though the boat is fully winterized.
 
For cold winter stayaboards:
Engine room vents: I use Reflectix and Velcro.
Exhausts and bilge blower: Closed cell foam plugs that can be removed to periodically run the engines and generator during the winter.
Other hull openings not needed for staying aboard for winter: closed with Reflectix.
Cockpit curtains: 1/2" closed cell foam strips to close off the foot of curtains
Salon windows and forward cabin hatches: shrink film or plexiglass interior "storm windows"
Water tank, pump and accumulator tank and lines: temperature triggered electric cable and insulation
 
I installed the Govee temperature sensors on my boat this weekend, pretty cool to monitor and watch.

I have more of a heat issue than a freeze issue here. 2 kinds of devices are watching the temp over the top.
Switchbot Meter Plus
Blink Cameras
Used to have a lot of LaCrosse stuff, but the annual fee and flaky operation cured that.
I monitor Beach House, and my 5th wheel, an hour and a half away.
Forget what I said in January. This is better.
