Fast delivery and well made item

For AC MAINS Dimmer - MPDMv7.5

I haven't quite got round to using this yet as it is going to be used as part of a university project. The board is very well made and arrived well packaged. I look forward to using this and will post further info when i have completed my project.

Relay Impressed,

For AC MAINS Dimmer - MPDMv7.5

If you have purchased an ESP8266 equipped device you should have some idea around how to flash it, so didn't relay need much in the way of documentation.
it came preloaded with firmware than enabled you to connect to it via wifi and control the Dimmer module, i decided to flash it with a custom version of Tasmota that supported the DAC.

the DAC provided me with smooth dimming. only 1 or 2 slider positions led to a momentary flicker, i used a couple of LED dimmable bulbs, the cheep ones seem to buzz and flicker more so its worth spending the money on that side of things,

Currently have my MPDM setup with Tasmota as an MQTT device on my network, and have Node red switching it on at 1% dim level and increase to 100% over 30 minutes every morning to act as a SAD alarm clock, (Artificial Sunrise Lamp).

Cost wise i think the unit was a little on the high side but i'm happy to pay for the convenience of it being all ready assembled and ready to use. it arrived within 3 days. The build quality looks good and the end results have been worth the investment. still cheaper than buying a off the shelf SAD lamp and with a lot more functionality and control.

Pro's
The power supply is on board
has a mains side fuse.
has pin out locations on the board to aid in adding things to the 8266.

Room for improvement:
Could be worth having a link to the shipped firmware just in case people wanted to go back.
could also be worth a link to custom "DAC compatible tasmota firmware" as could be a time saver for people.
no connector for mains side earth pass though.

Would buy again,

Thanks,

Awesome product, awesome team

For Universal AC MAINS Dimmer - MPDMv4.1

I have bought some (8pcs) of MPDM4 and I can't tell how awesome they are, how smooth the dimming is and how easy is to integrate them in any IoT automation.
More than that, the NextEvo team is amazingly fast in providing any help/documentation/support needed for their customers. Well done, way to go.
Congratulation and thank you for everything.

Device awesome, documentation missing

For AC MAINS Dimmer - MPDMv7.5

I am using the device in a Home Assistant setup, so I wanted to flash Sonoff-Tasmota on it.
The non-DAC version should probably be supported out of the box, by using the "Generic Device"
I ordered the version with the DAC, so that was a bit more difficult to get running.

I implemented a first try at:
https://github.com/arendst/Sonoff-Tasmota/pull/3015

This enables dimming with the DAC using the Tasmota firmware, MQTT and webinterface.

Very good product build

For AC MAINS Dimmer - MPDMv7.5

Using the ESP + i2c DAC combo, getting fast and *clean* results when used as a light dimmer, even with the ESP8266 busy irregularly (running complex servers on the chip: web, udp osc, UI, ...).
Documentation needs some improvement, diagrams missing, but other then that - it's a safe and well done product !
