Review: Topens Gate Opener System (dual opener, wired switches, remotes, etc.) - I purchased a complete Topens Dual Gate Opener setup (A La Carte) including: PW502 Opener, TC196 WiFi Remote, ERM12 Remote, TC175P Wired Keypad, TEW3 Vehicle Sensor Wand, and ET24 Gate Lock. After setting up and adjusting the gate travel, everything works as expected. One significant issue I had to work thru with the support staff at Topens was the inconsistent operation of the TC196 WiFi Remote that works via your smartphone. Although my indoor setup is well within the 230 meters from the gate controls (mine is about 50 meters at the most), the operation was inconsistent. It may work one day and not that afternoon. After several exchanges with Topens support, they suggested an external antenna ( https://www.desertcart.com/dp/B094MW1YMV/) that has fixed the issue. One additional tip I would offer is when you are setting up the TC196, the "paring" sequence MUST be done as fast as possible. It appears the main board only has a few seconds to press the momentary switch on the main board, then press "A" on phone, have lights flash and press "A" on phone again. It took me multiple tries to get it programmed. Again, after solving the issues with the TC196, all the operations of the gate and related components appear to be working as expected. Thanks again to the support at Topens for assistance in getting everything working!
Review: Extender needed for my application - After installing the Topens RK 1200T sliding gate opener, I couldn't program the 6 remotes I needed to operate the gate. I contacted customer support via their portal and explained the problem. They had me do a number of tests and send some photos. They decided that I needed this Topens ERM12 Universal External Receiver for my application. The sent me one free of charge. I installed it and the remotes programed easily. I can operate the gate from 100+ feet from our house. Very good product and excellent customer service. The entire gate system works well and is of good quality.

### ⭐⭐⭐⭐⭐ Topens Gate Opener System (dual opener, wired switches, remotes, etc.)

### ⭐⭐⭐⭐⭐ Extender needed for my application

### ⭐⭐⭐⭐⭐ Extended range, works great with some undocumented setup
*by C***Y on October 10, 2024*

I installed this range extender on a Topens gate opener. After installation, which was easy to wire into the control board using the gate opener instructions. After installing, however, the gate wouldn't open and close each time the button was pressed. After talking with their support, they sent the attached instructions for erasing the codes on the control board and learning them only on the extender. With both the control board receiver and the range extender receiver accepting remote signals, duplicate signals were getting to the control board. The gate opener now works with a much better range. Hopefully these instructions help someone else.
