I have some sensors on a hognose enclosure and I can say for sure stay away from INKBIRD stuff. It integrates poorly and fails on loss of internet connection.

I don’t have a good solution for the heatmats yet but I’m looking into integrating an aquarium controller I have laying around to manage that.

For hygrometers there are a ton, but you’re going to want to look for low power and probably zigbee. the majority of the sensors I’ve tried have been an annoyance to manage batteries but the zigbee ones seem better.

Where? I never see the weird stuff cheaper than gTLD’s

I’ve frozen peeled garlic before and then grated it into sauces. It’s fine but if you want to use your excess garlic for something delicious you can make confit really easily which should extend the shelf life quite a bit.
