Tasmota DevGroups Wiring Diagrams

We want the smart bulb to always have power allowing full control through home automation software and wall switches. Adds functionality without having to teach yourself and house guests how to turn a light on and off.

TASMOTA Device Groups allow multiple tasmota devices to sync changes to each other. Click your light switch and it sends off or on to the members of the device group.

Push the dimmer down on a dimmer light switch and have the smart bulbs dim as well. This page won't go into how awesome devgroups are but just shows how to wire things up physically to allow the software to sing.

Single switch

Scenario 1

In this scenario there is a single pole switch that we don't want to have the relay turn off and on the lights. We want the smart bulb to always have power and through software tell it to turn off and on.

We have one wifi smart switch or dimmer running tasmota and one wifi smart bulb running tasmota using devgroups to control each other.

3-Way method with single pole / dimmer switches

There are times we don't need to use a full three way switch to have three way functionality. We can use the software to emulate a 3 way setup and using tasmota devgroups

Scenario 1

In this scenario we want to allow single pole switches or dimmers control standard bulbs in a three way configuration. Because we are using single pole switches we won't need to use all the traveler wires that a typical hard wired three way switch requires and so we will cap one of the traveler wires off in each box. In this scenario one of the switches will actually use it's relay to turn power off and on to the standard light bulbs.

Scenario 2

In this scenario we want to allow single pole switches or dimmers control wifi smart bulbs running Tasmota in a three way configuration. Because we are using single pole switches we won't need to use all the traveler wires that a typical hard wired three way switch requires and so we will cap one of the traveler wires off in each box.

We will want to give continous power to the light bulbs and turn them off and on with software. Because the switches / dimmers won't need to use their relays to power off and on the lights they will just use devgroups to keep in sync with the bulbs.

Sonoff iFan03/iFan04 with Smart Bulbs

In this scenario there is a single pole dimmer switch that we don't want to control the lights or fan. Instead we'll utilize it's buttons to control the remote smart fan controller (IFAN03) and smart bulbs both running Tasmota. The iFan04 is the same product as the iFan03 except the change to accomodate US 120V fans. We will want to give continous power to the light bulbs and turn them off and on with software. Because the dimmer fan controller won't need to use their relays to power off and on the lights they will just use devgroups to keep in sync with the bulbs. The output of the dimmer switch will be capped off and the output of the IFAN03 for lights will be capped off.
