Wifi-enabled GU10 dimmer switch - simple as possible!

[trebnamo]

For about ten years I've had one of these running the two sets of six GU10 downlighters in our kitchen: https://www.ebay.co.uk/itm/257296291840

I don't use the lightwave hub or app, I have a mixture of domoticz and HA-Bridge making everything appear to be a Philips hue bulb to smart assistants and other stuff. All other devices controlled by this setup are almost all plug sockets or similar. They all just patch on to my wifi and get predictable addresses filtered by MAC. Which is hacky and horrible but works for me. The lightwave dimmer is the odd one out because it will only speak 433MHz, so I have to have an RFXCOM USB adaptor hanging off the device running domoticz. I now want to make everything wifi.

The difficulty I'm having is finding something that will control twelve GU10 bulbs with a physical switch OR a command over wifi. I've seen several choices, brands like Wiz Ive had success with as they need activating via the Wiz app but can then just be devices on the network listening for multicast. Other choices seem to be Varilight and Tuya, but the Tuya app seems to want cloud access, which the Wiz stuff doesn't - it still works even if I trap it in a very locked-down VLAN.

Can anyone suggest a simple wifi-enabled, two gang GU10 control for the wall that has a physical switch as well as non-cloud wifi control?

I thought Tapo had something- or get the bulbs, set them up as a group ?

I had thought of getting smart GU10s and this does work elsewhere in the house like on the landing, but the issue is a physical switch that can work as well. Any dimmer has to speak wifi otherwise a physical switch off at the wall requires a physical switch back on, at the moment you can do voice command or send multicast no matter what state it's on. I want to be able to do this and have a physical switch as well.

I'll check out Tapo, cheers for the recommendation!

I use sonoff mini behind the switch plate (needs a decent size back box). Makes it into a two way system so the physical switch can be in the on position with the lights on and vice versa but works well

This sounds perfect, cheers, will check it out.

Do the Sonoff need a neutral wire? That was the stumbling block for me when I looked a while back.

If so, Shelley do a range of "no neutral" wifi switches that work with a normal switch as well.

Right, I have received two Sonoff MINIR2 and I've hit a wall (not the one with the light switch in it). Would appreciate any pointers.

I ran through the DIY mode detailed at https://sonoff.tech/en-uk/blogs/news/no-tasmota-an...

Device presented an access point, I connected and opened 10.10.7.1, then got the prompt to put in SSID and password. The device then rebooted and asked my router for DHCP, which I then added to MAC address list to make it predictable. So far, so good. Sonoff is now 192.168.1.234 and visible on the router across multiple power cycles. According to the docs I should be able to POST to 192.168.1.234:8081/zeroconf/info with an empty JSON and get back information about the device, but it just hangs:

My terminal said:

% curl -X POST http://192.168.1.234:8081/zeroconf/info -H "Content-Type: application/json" -d '{}'
^C

Telnet and ping both answer, so it's not network or firewall stuff I don't think:

My terminal said:

% telnet 192.168.1.234 8081

Frustrating as it feels like it's 99% there. What have I missed?

Cracked it. JSON was malformed. Now all working

My terminal said:

% curl -X POST http://192.168.1.234:8081/zeroconf/info -H "Content-Type: application/json" -d '{"data":{}}'
{"seq":2,"error":0,"data":{"switch":"off","startup":"off","pulse":"off","pulseWidth":500,"ssid":"ap","otaUnlock":false,"fwVersion":"3.7.3","deviceid":"1001xxxxxx","bssid":","signalStrength":-73}}

I'll now be able to attach this to the GU10s and then get everything working with HA-Bridge, and everything will be wifi. Cheers again for the recommendation

Glad you got it all sorted, not least as mine was all very simple and I have no idea what you did to revtify the issue!
