Is there any relatively cheap zigbee hardware with PWM?

[Leopard]

Hi, is there any wireless IO like shelly relays, but so it would have transistor output to run Omron Solid state relays?

Would be nice just to able set pvm lenght from 100ms to 1s and then control on/off state just 0-100% value.

Idea it to reduce patio IR -heater power ~40% when sauna is running, as cabling to outhouse is done with 5x2,5mm2 witch (legally) allow max 16A fuses (~11kW) and stove is 6,9kW and IR heaters 6kW, so if all of them are running same time, it blows the fuse and sauna gets cold

Its hard to find anything for home and I don’t have money for simatic et200

Zigbee would be optimal as my garden lights are already those (from lidl, havn’t tested yet as I didn’t get my usb - zigbee adapter)

I’ve used ESPhome to write custom firmware for a resistive heater using Slow PWM and Shelly hardware…

Continuously toggling a GPIO pin?

Hi, I’ve a fully worked ESPhome example of a slow_pwm driving a towel radiator (resistive heater via a Shelly relay), which does have both period (period: 300s) and duty-cycle (level: 40%) control. The function of the output was checked via an oscilloscope, and the simple hack of defining a separate output pin mirroring the PWM relay - meaning the HASS History showed the exact timing of a Slow_PWM output directly (HASS as the worlds slowest logic analyser!). The code is complicated by my use …

I guess you could tack a SSR onto a Shelly for more current drive - some of these load type might offer closer temperature regulation with burst or “standard” PWM.

If this helps, this post!
