Hi
I would like to control the humidity inside a outbuilding in our garden. Plan A was to use a Meross humidity sensor (MS130) plus Meross Matter hub (MSH450) and Meross Smart plugs (MSS315) hooked up to a Smartthings automation. Having finally succeeded in adding the Meross hub and sensor to Smartthings, the distance between the hub and sensor is too great and/or too many walls in the way. I should perhaps have realised before but hey ho …
I can think of 3 possible solutions
(a) link home and outbuilding via WiFi, install an internet switch in the outbuilding and connect the Meross hub plus sensor and plugs to it (would need to buy a new WAP and switch)
(b) use an existing Zigbee humidity sensor and install a Zigbee extender in the house to connect the outbuilding an existing Aeotec hub. The smart plugs seem to work in the outbuilding already so would just need to buy a Zigbee extender
(c) reading other posts on this forum, it seems like Tapo might be another alternative. (I think) I would need to buy a Tapo humidity sensor plus hub and smart plug (if I were unable to add the Tapo service to ST).
Option (b) would be the cheapest but prefer simplicity of set-up and robustnessover cost. Or maybe there are other options to consider? Would appreciate some guidance - thanks in advance!
Your b solution looks good. If your existing sensor already works into SmartThings and reports timely (look in HISTORY to find reporting frequency) all you need to do is add a recent issue plugged in Zigbee device such as a Sonoff ZBMINIR2 (about $15) installed into SmartThings and it will act as a zigbee extender/amplifier. You can check the routing in the SmartThings app under the sensor tile. The rooting will appear a few hours later.
Meross: The MSH450 hub works great when hard wired, but I find it unreliable on WIFI. The MS130 reporting interval on humidity is way too long to be useful (few hours). I use MS100f sensors which report at 20 minutes interval and when paired with the MS450 hub instead of the MS300 (recommended for the MS100f sensors) become fully Matter compatible and automatically transfer to SmartThings. I have 2 MS450 hubs and after attemps to use it on WIFI as an extender, I simply keep it in its box as a spare for now…
Hi @murvic thanks for your comments.Bizarrely, the MS310 has just showed up in ST around 48 hrs after adding it to the Meross hub. Readings seem to be every 10 mins or so. Might get a Zigbee extender anyway in case the MS310 decides to go AWOL
Great!
I have noticed that Meross WIFI devices no longer show up in the transfer link… Then they show up in SmartThings completely out of the blue. This is recent. Once they appear, they work.
Best of luck
Hi @Andreas_Roedl - thanks! I have the Sonoff SNZB-02P sensor but couldn’t see it on ST (there are two brick walls and a steel fridge between sensor and hub) hence my thought about getting a Zigbee range extender
