I’m very happy with my Shelly devices (Shelly1s, PM, EM). You need a good wifi network though.

Looks like there is a serial connection between the esp board and the board in photo 3. (See connector cn2). It probably has a tuya serial chip, which means you need to figure out the serial commands to send and listen to. There are some similar setups: Alfawise Air Purifier (P2 (Wi-fi Version)) Configuration for Tasmota and Kogan 500ml Aroma Diffuser (KASHSMARDFA) Configuration for Tasmota
esphome supports tuya serial too Tuya MCU — ESPHome and the links there.

G’day HA enthusiast,
I just wanted to report that “Arlec Grid Connect Smart Outdoor Timer”
($25 in Bunnings) works fine with LocalTuya integration, including power monitoring.
I’ll be using it to turn on pool chlorinator (which results in turning on a pool pump) and potentially also use second one to do power monitoring for a pool heat pump (Madimack Elite V3 which I successfully integrated with HA by adding a support for it to Tuya Local).
I was previously using Kogan plug with Tasmota (inside of Excalibur 6 Outlet Outdoor Safety Box) to control the pool pump/chlorinator, but after about 10 months, it finally failed - I’m hoping to have more success with this one since it’ supposed to be suitable for “spa pumps or other heavy duty devices” (“Total load must not exceed 2400W”).
I added more info to [Home Assistant] Australia - Electrically Certified Hardware (tinyurl.com/ha-aus) - Google Docs.

Hi Australian HA folks,
if anyone is interested in buying OpenSprinkler (irrigation / sprinkler etc controller - works with 24VAC valves from Bunnings) or OpenGarage (controller for your existing garage opener), let me know. I ordered more than I needed (when buying it from the US) so if you want some, please message me & we can share the shipping cost (and you’ll get it faster than from the US as I already received the delivery).

Thank you. I’ll take a look at those links.
jesserockz gave me some similar pointers on the Discord thread.
No luck with tuya-convert so I’ll try serial soonish.
I was thinking this or rain machine? Did you look into that?
I could be interested, I’m in brissy
Hey guys.
I had an update in ESP home this morning, did the upgrade and now my brillant PM switch is dead
Maybe not connected, I have had another one die as well.
What’s been peoples experience with these?
I live nearby to the seller so just picked up from their warehouse, seem like a distributer of some sort. Accepted my offer of $12 for one. Connected first time no problem to my zigbee2mqtt cc2531 setup and also does energy monitoring. Will definitely buy more from them if I need more smart plugs.
That’s a big discount from the listed $40 plus delivery!
Haha i wish! That listing is for three, they have another listing for $15 each
Nice work.
I did very similar but used the arlec outdoor smart double plug, which also has energy monitoring. One for my chlorinator/ filter pump and one for my heater pump. My actual heat pump is a big 3 phase 30 kW (5 kW input), so I’m going to use a Shelly to measure it’s power/ energy.
I have an old VX salt chlorinator and it took a while to work out the best option. If I switched the pump on/ off the chlorinator would switch to standby with low flow alert but wouldn’t switch back on. If I switched the chlorinator on/ off it would restart in auto mode but wouldn’t switch on the pump until the timer was correct. But the clock would reset to 00:00 every per cycle. I finally got the second option working correctly by setting the start time to 00:00 and run for 6 hours. Now when the power cycles it thinks it is midnight and starts the pump for 6 hours, so success.
I haven’t got to local_tuya yet, but it is on the cards.
The sockets work fine with the core tuya integration, but reported power is out by factor of 10, which I fix with a template. The tuya integration doesn’t report energy, so I use the integration function to calculate. The tuya app does report daily energy do it is something to look at for the HA integration. I believe the data stream reports add_elec, which is just the delta on energy consumption, not running total. I find I need to manually reload the integration a lot to get regular updates, so I’m hopeful local_tuya will improve this for me.
Trying to get a consensus as I’ve seen a few different opinions, do you have to have a light switch for a light in Aus, or can it be ‘hardwired’ on?
Reason I ask is (an electrician will be doing all the work) I bought these Philips hue wall switch modules as I hate the remote style option.
Basically they’re small zigbee modules that have a 5yr replaceable battery that you wire to the light switch after connecting the existing wires together to be ‘always on’
The idea is 1 - a nicer / normal style light switch
2 - stopping people from accidentally turning mains power off to the hue lights.
I’d be swapping to ‘doorbell’ style mechanisms so the switch is always in a default position.
Ideally I do get them hardwired as if I have an issue with a bulb (which I never have) I could just unscrew it to reset it.
The alternative is to take the faceplate off the existing light switches and replace it with a blanking plate, which could just pop off to access the switches if need be, and then install another mounting block and switches next to it.
Id prefer not to do this for space and looks, but I can’t find a definitive answer if switches are needed just for sockets, sockets and lights or sockets, lights, fans

Can I check with the Shelly (I have read through their manual) - if you use it as a manual switch, rather than via the app or HA, can it still operate as an auto-off?
What I am looking at is the boost switch on my solar hot water heater. If I set up auto-off in the app, can I walk over to the switch, flick it on (momentary switch) and have it auto-off in say an hour?
yes. I use it this way for my garage door. I set the timer however for 1 second, to ensure the shelly switches itself off after triggering the door.
so yes.

I haven’t looked into Rain Machine - i wasn’t even aware of that one.
I was tempted by the fact that the OpenSprinkler is open-source & works with HA straight out of the box.
My heat pump actually has 15A plug (I completely forgot), so I can’t use the smart plug for that either. Sound like it’s time for me to try out Shelly or IoTaWatt.
Oh interesting, so you have 2 separate pool pumps? My heat pump installers re-used the existing pump & added a controller which turns on the pool pump when either chlorinator is on or heat pump is on (or both obviously). This makes the automation super simple - I only control chlorinator (smart plug) or heat pump (LocalTuya) and the pool pump is automatic.

I did research before looked pretty good.
Read a long whirlpool thread on it after seeing this, it’s pretty much 50/50 between the two.
If you prefer open source or if you want easy out of the box. Nowerdays I prefer out of the box ease.
Maybe when the kids are older I can go back to fiddling with these things
Anyone here got a pool heat pump that connects into HASS?
Yes, I got Madimack Elite V3 (very new model from late last year - pretty silent & efficient) working using tuya-local. The setup is not trivial as you need to retrieve Tuya’s “localKey” (needs e.g. rooted Android phone; there are a lot of how-tos, but often outdated, so in my experience, it can be a bit of a pain to figure out a way which works for you).
Anyway, now it works well & locally - it works as a Climate - can control mode (off/heat/cool/auto), target temperature, power mode (low/medium/high), read current power level (%) all the temperature sensors:
(I also had to create new mapping for it - https://github.com/make-all/tuya-local/pull/77 - but that’s now reusable for everyone 
)

@PetrK you legend!
That’s amazing, I got a Tuya fan so I know the challenge of getting that local key.
Great to know these are on the market!
