ChacOn RSL366 switch	Works	Works via ESPiLight with arctech_switch_old type Saved copy … deprecated and you don't give support anymore. Thus, I have a big problem and maybe you have a short advice to point me in the right direction. I have a ChacOn switch that identifies itself as a RSL366. Even on the back of the plug this information is given. If I analyze the code sent by the remote I get the following Information: Valid message: [rsl366] {"systemcode":4,"programcode":3,"state":"on"} Valid message: [rsl366] {"systemcode":4,"programcode":3,"state":"off"} But the JSON file in Homebridge fails to send code.

Elro sockets and remote	Partly works	Control works; remote press switches all sockets Saved copy Hi, thanks for that nice integration. First of all, the code is working fine to control 5 different elro sockets from Homebrige UI and Homekit. But there is an issue when receiving a signal from the elro remote control: No matter which "on" or "off" button is pressed (unitcode), homebridge always set on ALL switches to on, or all to off. The log clearly reports the correct systemcode and unitcode, which correspond to the configured switches. I am using ESPILight. this is my switches config: [code] and an example from the log: [code] What is wrong here? thanks, Hendrik Excerpt saved from GitHub on 2026-10-22.	Issue #30 · 2023-01
433 MHz dimmers	Requested	No dimmer support; user prototype Saved copy I might me missing something, but I do not see any support for dimmers. This should be possible using the ESPiLight protocol, but I am unsure how to add them in the configuration. Excerpt saved from GitHub on 2026-10-22.	Issue #19 · 2020-05
