PWM to 0-10v analog converters need 24v input

[ledgardeneruk]

As above, it works with 12v but it's way off on the ratios. With 24v it's as good as I mentioned in a post, about 15% accuracy across the range and no wander after 12 hours so far. Im going to start an automation dimming it up and down etc so see if it starts to go off track and needs the pot adjusting.

In your diagram it shows 12-30v. It needs to be 24v min. Will try and test with 30v soon also.

If you really think that the voltage will “wander” over time, you could track it with one of these https://www.instructables.com/Arduino-Voltage-Sensor-0-25V/

I'm going to get myself a couple of these converters with a couple voltage sensors. I will setup a automation and run it for a month or two and see what happens. I'll also test it out with 12 and 24v power supplies and see what kind of results I see and let you know.

I picked up a couple of these about a month ago and just arrived from AliExpress. £6ish each.

No idea if they are Zigbee or WiFi on the box or manual but I did order Wi-Fi.

I do have a Zigbee 3.0 dongle for the Pi if needed though. Although I'm using Unraid in my server as my main Home Assistant can use Home Assistant Remote which creates a master and slave type setup so I could have 3+ houses or linked etc under one instance. It's good for redundancy and also spreading Zigbee in my case as Pi is closer to LEDs.

These are meant to give out a true 0-10v like the DAC. Designed for exactly what we need.

If you look at the tiny manual below you will see it's for dimming drivers.

Be sure to give us an update how it goes configuring it.

No idea what's inside it till I Google but think it's Zigbee.

Edit: just googled it and it's a eWeLight Model ZYZB010 and supported by most! https://zigbee.blakadder.com/eWeLight_ZYZB010.html

Got some photos of the insides, not much really:

Suspect that this is the Zigbee module

No doubt - Like that it is all self contained including the power supply!
