Lamp control via WiFi, without N wire - which module?

Question

Hey I need control of the lamp via WiFi Connection without neutral wire . The module should fit in an electrical box. Fine if: - popular/easily available/inexpensive - simple operation Would the following relay be good? ZigBee relay OXT 2CH TUYA 2CH ZigBee Inductive Relay without N . . . . (I...

You suggested a link to the ZigBee version. This will only work with a ZigBee gateway (ZigBee-Ethernet/WiFi adapter). Look for the WiFi version.

freebsd · Answer

Will the maximum allowable current load of the above relay be sufficient?

Matheu · Answer

Lamp I will install:
- if LED then max 30W
- if ordinary (i.e. traditional light bulb, i.e. resistive load) then 200W - I give a large margin.

(the load capacity of the relay according to the manufacturer is max 2x100W LED, or max 5A )

Matheu · Answer

Maybe I am looking wrong? - but I have not seen that at the same time the module has:
- a WiFi version
- and at the same time the possibility of connecting without a neutral cable

I do not know if it is possible without buying an additional module - a separate WiFi gateway.... ?

See for example Allegro auction number: - 15037745739 - 15113316446 - 14229536137

Thanks a lot, Freebsd - I have looked at these auctions! 1) I understand that if the module has a WiFi connection it no longer needs to use an additional ZigBee gateway, right? 2) The following modules (Forta) should be compatible with popular software? 1) Forta P2N-.W WiF Load range: 10-100W per circuit Wifi standard: 2.4 GHz 802.11 b/g/n Compatible with: Tuya Smart / Smart Life / Google Home / SmartThings transmitters: 2 TRIAC BTA16-800 thyristors capacitor included: module - 2 CBB22 205J400V capacitors, total capacitance 4uF Module dimensions: 39 x 39 x 19 mm Capacitor module dimensions: 40 x 30 x 22.4 mm (can be exchanged for a smaller one) This module has an N connector, but I guess it can work with and without the Neutral wire attached: - When pairing with the TUYA app - the load is to be at least 10W. - In an installation without a neutral wire, a capacitor is to be connected in parallel to the load (capacitor is included). - In case of blinking light, it is recommended to replace the existing capacitor with a stronger one (e.g. 10uF) 2) ZanderParts TUYA WiFi Relay 4x150W, 4x2,5A from the auction description- Requires a full power supply in the box - L and N -> at my place, unfortunately, it falls off... 3) Forta PBN-.W WiFi Power max. 400W Storage after power failure Wifi standard: 2.4 GHz (only) 802.11 b / g / n Compatible: Tuya Smart / Smart Life / Google Home / SmartThings Size: 47 x 47 x 20 mm In an installation without a neutral wire, connect the capacitor in parallel to the load (capacitor included).

You do not need a ZigBee gateway connected to the internet. You need a WiFi router with internet connection. In the description it has compatibility with Tuya. According to the description, it works without N. By default it requires current flow to have energy to operate. Therefore the pairing of the device is best done with the light (relay) switched on You should also immediately add a capacitor at the light source if the lighting is e.g. LED type.
