Their gates are pushed by using connections to tp3 and tp2. For the redbear ble nano (v1.5), proven within the pictures, there are connected to d7 and d5. The redbear ble nano v2 has a distinct board layout and for that module they're connected to d9 and d8. This task lets in current houses to be without problems retrofitted with remote controlled lighting fixtures. The prevailing wall switches preserve to paintings although the far off manipulate circuit must fail. No addition wiring desires to be run and the mild can nonetheless be remotely turn on after it's been grew to become off with the aid of the wall switch.
Going ahead, retrofitting your home light switches with ble nano v2 manipulate modules that supports bluetooth v5 manner in the future you could installation a house extensive automation community the usage of a bluetooth v5 mesh. Above is the wiring diagram for connecting the ble far flung manipulate light switch to the present wall switch in order that each the wall transfer and the ble far off control can operate the light. A pdf version is right here.
The present wall light transfer continues to work even if the faraway control circuit fails. In case you can not discover your cellular, or if the far flung manipulate circuit stops running, you can still use the wall mild switch to show the light on and stale. Because all the light bulb modern has to waft via the zener energy supply when the switch if closed (and the mild on), the zener must be deal with this current. For a 5w 5.6v zener the most theoretical modern-day is 0.9a. In exercise to run this zener at 5w requires a big warmth sink and your wall transfer might be distinctly warm. So i advise restricting the zener wattage to approximately 2.5w or about 0.45a. With a 240v mains this boundaries the lamp to approximately 100w. For 110v mains the limit is about 50w (say 60w == zero.55a == 3w inside the zener). Given the increasing use of led lighting fixtures i think this problem on lamp wattage is acceptable.
