Kincony A16 - PIR motion sensor

With the 868-A6 can you extend the number of relays through the I2C bus or by some other means? If it can be expanded what do I need? Is there a limit of sensors on the I2C? I read somewhere that with the RF module there is no limit if one is using that option. Can you explain how the RF module provides sensor expansion please?
Given the A6 has not wired Ethernet, is there any options to power it from an injector or should we consider the A4 instead?
If in our project we wish to run two A6 units can they be linked (master/slave) or are they separate? We are creating an automated garden and greenhouse system including irrigation management and monitoring, vent control, multiple water and air temps, soil moisture and acidic levels, sunlight and baro pressures. We wish to be sure the A6 relay control can be expanded and sensors quantities are not limited.

We are also trying to determine if a closed loop system with rules and thresholds can me met with Tasmota or if we need to write our own code, any advice would be greatly appreciated.

Regarding the RF module option on the A6, when its installed, how is the plastic cover meant to be installed since the RF module protrudes outside the case? It would seem I either bought the wrong case or we are expected to cut out part of the case....please advise.

KC868-AP ESP32 PWM Dimmer Released

Posted by: admin - 12-30-2022, 08:31 AM - Forum: News - No Replies

	We have designed KC868-AP. It is a ESP32 16 channel PWM dimmer board. It use PCA9685. The PCA9685 component represents a PCA9685 12-bit PWM driver. It uses I²C Bus for communication. every channel output have MAX 3A driver chip. KC868-AP support use by ESPHome in home assistant. It also have digital input and relay output.

Upcoming house build

Posted by: bluepr0 - 12-29-2022, 01:48 PM - Forum: DIY Project - Replies (10)

Hi!

I'm in the process of researching to build a house and have a centralised place to control lights, blinds, etc.

Needs & Goals

Have ESPHome Ethernet boards with relays I can control using regular light switches (momentary switches too) or through home assistants automation. This could be used for lights, blind motors, etc. Won’t need more than 16A per relay
Have ESPHome Ethernet boards with PWM dimming capability for 24V analog LEDs with 3/4A Per channel. I created 1 channel mosfet board as a proof of concept dimmer with LEDC component from ESPHome and it works okay.

Questions

As I understand relay boards will work with switches, but Would relay boards work also with temporary switches / push button?
Are these board 0 delay when activating the relays? My main goal is to have an immediate response from the moment the switch or the command is triggered to when the relay turns on. I have seen some videos where a lot of relays are turned on at the same time and they seem slow.
Is there any video of relay and dimmer board using ESPHome to see the speed? What’s the max Amp per mosfet channel?
I’m honestly VERY lost on the product line. I have seen KC868-A8 could be a good fit (at least to do an initial test). A 16 relay version doesn’t seem to exist?. KC868-E16S seems another interesting one but it goes really high on price so I will need to be 100% sure about speed
I’m still in research phase but I’m assuming a house will need at least 32 relays, and might or might not be all boards in the same placement. So I’m thinking it might not be a good idea to pick one big board but maybe several smaller ones?
What products do you guys would recommend?

Thanks!
