Very disappointing handling of a small mistake on their part. The pre-programming (free for orders of 6 or more) was not carried out, even though this was clearly stated in the comments with the request. First response: “Not checked, so tough luck” — according to them, the system cannot process this without payment. After several emails, there was no real solution. As a “compensation,” they suggested returning everything, which is not very realistic. This could have been resolved much more simply and customer-friendly, for example, with a quick phone call. What a shame.

Dear Tim, Thank you for your review. We are sorry to hear that you found this situation disappointing. Your order included a note stating that the motors needed to be pre-programmed. However, in our ordering system, pre-programming is processed as a separate option, as clearly indicated on the product pages. Since this option was not checked and no charge was applied for it, the motors were automatically shipped without pre-programming. This has caused confusion afterward, and we regret that. When you contacted us about this, the goods had already been picked up by the carrier. At that point, we could no longer adjust the shipment. Therefore, we immediately offered to have the order returned at no cost, to program the motors according to your specified configuration, and then to send everything back to you at no charge. The UPS return label was provided by us, and there were no additional costs for you. To minimize any time on site, we also sent an instructional video along with the order, explaining step by step how to program the Somfy RS100 IO. This allowed you to assess whether it was possible to perform the programming yourself without returning the items. We understand that a return may not always be desirable when installation is already scheduled. At the same time, this was our way of ensuring that the pre-programming was carried out correctly and completely according to your wishes. We take your comment that this could have been resolved more simply or personally to heart. Feedback like this helps us to further improve our communication and processes. Best regards, Team Tromm

Help with installation leaves much to be desired.

Dear Jackie, Thank you for your revised review and your feedback. In your situation, there was a technical incompatibility between the Sonesse Ultra 30 WF RTS Li-ion motor you purchased and the existing IO control. The motor in question operates on the RTS protocol and therefore cannot be paired with a Situo 5 IO transmitter. RTS and IO are two different systems that are not interchangeable. Following your report, we explained via email that you need a Situo 5 RTS for this motor to connect and adjust it correctly. With this, the motor can be operated and integrated within the RTS system. When working with TaHoma, it is important to use the correct protocol or to work with compatible products. We understand that this can be confusing in practice, especially when multiple roller blinds in a home operate on different protocols. At the same time, this is not an installation issue with the motor itself, but rather a matter of product compatibility. If you would still like us to assist you in finding a suitable solution within your existing TaHoma configuration, we would be happy to help. Best regards, Team Tromm
