Remote control for Webasto and Eberspacher heaters using mobile app

This is the fifth generation of our popular GSM remote control for Webasto and Eberspächer heaters
Remote control your preheater or airheater in your car, truck, boat or other recreational vehicle rv with a mobile or landline phone using phone calls, SMS or iPhone and Android app. GSMS-PH5 is designed to work with heaters that require a analog switch-on-signal (+12/24V) or W-bus. It also has two potential-free outputs that can replace a existing on/off switch. Contact us if your are unsure!
We offer a 2-year guarantee on all of our products!
The GSMS-PH5 unit is developed and manufactured in Sweden* and rigorously tested & well proven. We use only high quality components from authorized distributors.
Easy to setup and use but packed with functions. Supports GSM quad-band and will work worldwide. Buy the start/stop pushbutton with indicator LED to control heater without the APP. Works on both 12V and 24V systems, control the heater in your truck or other heavy equipment. Schedule start; select a time and date in the future when you want the heater to start. Easy IOS and Android app available, "GSMS Remote Control" in Appstore and Google Play. Also works with Webasto and Eberspacher native apps; "Thermo Call" / "EasyStart GSM". Control and setup the unit directly in the mobile app. No programming skills required. Can be used free of charged with phone calls as it does not answer the call. Works like Eberspächer Calltronic / EasyStart GSM and Webasto ThermoCall TC3 / TC4. Low power consumption and high strength signal coverage thanks to the external antenna. Two potential free outputs and W-bus support makes it suitable for most heaters. And much more!
The only thing more you need is a SIM-card, read more about it HERE.

GSM-START.SE Thank you for your feedback. Have a nice day!


Works perfect with Eberspacher installed in Audi A4. Five stars and highly recommended!

This would be nice to have for me: I like to use the SMS confirmation and only feature request would be to see battery voltage in the return SMS before heater start to evaluate battery state of charge easier.

GSM-START.SE Thank you for your feedback Tuomas. I understand what you mean. First I would like to point out that most heaters will have low voltage detection built in to prevent draining the battery but we will consider this in the next design meeting as I think it is a good idea and easy to implement and lets the user make the final decision. Thank you. Best regards, Andreas


Installed it in my caravan. so nice to be able to call it!
