Temperature Monitoring in Van
Does anyone currently monitor the temperature in their van while away from the vehicle? I'm specifically concerned about our two small dogs that we may leave in the van no more than 2 hours. I want to keep track of the temperature via phone while in a restaurant, house, etc. All I've found are high dollar subscription services. Any helpful suggestions would be appreciated.
Please no lectures on having pets in a van for 2 hours. We do have a roof AC/heat unit and we're doing research before we'll ever leave them, if we do at all. If we can't find a good monitoring solution, we won't leave the pets in the van.
