Overview

The My Thermostats app is an app to control wifi-enabled thermostats. Currently, it only supports the following thermostats from Radio Thermostat:

• CT-50, CT-80, CT-30 and 3M50 supporting firmware version 1.04.64, or later

System Requirements

The app is currently available on the following platforms:

• iOS (iPhone)
• Android

Desktop applications for Linux, MACOS and Windows may be available in future if there is a demand.

Background and Context

Radio Thermostat provides a wifi-enabled thermostat product. On May 15, 2023, Radio Thermostats decided to discontinue the mobile app they provided to remotely control their thermostats. This meant that a lot of customers could no longer remotely control their thermostats.
Wellfleet Software created this mobile app to enable users of radio thermostat products to again be able to remotely control their thermostats. We plan to support other thermostats and additional features as we see a demand for it.

Configuring a URL For Your Thermostat

The app requires the URL (internet address) to your thermostat in order to communicate with it. A typical URL looks like http://<IP address or hostname>:<port>. In this URL the <IP address or hostname> part identifies the address of your router on the internet (also known as WAN address).

Dynamic DNS Service

Most internet providers do not assign a hostname to your router and only assign a temporary IP address. This temporary IP address may change without notice. To get a stable address for your router we recommend using a dynamic DNS service provider. Here is a review of dynamic DNS providers you may consider.

If your internet provider assigns your router a static IP address then you do not need a Dynamic DNS Service and can simply use the static IP address of your router in your thermostats URL.

Port Forwarding

The app needs to communicate with your thermostat and not your router. This requires you to configure a port forwarding rule in your router so that when the app sends requests to a port on your router, the router forwards that request to your thermostat. Here is an article on how to set up port forwarding on your router.

When configuring a port forwarding rule you can choose any available (unused) port on router. Ports are usually available between 8090 and 8020. The forward that port to your thermostats IP address within your local network and the port used by your thermostat (typically port 80).
