12V AC dimming

peerkersezuuker 26 Dec 2016, 14:32 last edited by

Hello, i have looked arround but i cant seem to find any examples.
I want to dim 3 x 12v AC ledbulbs in my kitchen seiling, and i was wondering how to build one with Mysensor controll.
So input is 12v AC, wich should feed the mysensor node (converting ac-> dc) and dim my 12V AC led bulbs.
Any suggestions on this ?

With regard's

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Hi, I'm glad CodeGarage is taking over! Please are there any updates since January what's happening? The GitHub repo hasn't gotten commits for over a year. Thanks!

It looks like duplicate email notifications may be linked to system settings or preferences. Have you noticed if the issue happens after specific actions or changes? Investigating your notification settings might shed some light

Well, my network with two handfulls of nodes in three different locations is still live and kicking! I agree that there does not seem to be a lot happening in the community. I'm running 2.4.0- alpha since this gives support for MQTT over TLS. Just managed today to create one more MQTT GW after reading a lot about support for ESP8266. You know, these things you do once per year and have to learn new each time. MySensors is the cheapest way I have found to create small sensor nodes etc. But now slowly running out of my supply of hardware. Well, time will tell...

Hey! If you're using ESP32 with LoRa (RFM95) and a Raspberry Pi gateway, here are some quick tips: Hardware: Heltec ESP32 + LoRa boards work great with MySensors. Power: ESP32 (~600mA) + LoRa (~120mA) can drain batteries fast—Arduino might be better. Software: Use Arduino IDE for ESP32 (try EnergyMeterPulseSensor), and set up an MQTT gateway on the RPi. Home Assistant works well for data visualization. Real-World Tips: MySensors + LoRa is great for farm/weather monitoring—checking similar projects can help.
